Billionaire Collection #4

The Billionaire's Forbidden Little Sister

Rate this book
Theo Cruz, a New York man known for his family’s billion-dollar empire, Cruz Enterprises, has been indicted this afternoon in the Court of Public Opinion on charges of Bro-Code Conspiracy.

Chief counsel for the prosecution, Caplin Hawkins, spoke candidly about the accusation. “Once thought of as a best friend to many—including myself—Theo Cruz has officially turned his back on human decency. He’s conniving and dishonest, and a habitual offender of Bro-Code Law 676. He’ll rue the day he forgot that you never—under any circumstances—get involved with your best friend’s little sister.”


Fact: I haven’t actually been arrested or indicted.
More important fact: I inadvertently messed up—big-time.

Two strangers in a foreign country, we said hello.
Hello turned into a kiss.
A kiss turned into a rendezvous.
And a rendezvous turned into more than I’d ever imagined.

But her unruly golden curls and beautiful body hid an important detail—She’s my mouthiest billionaire best friend’s forbidden little sister.

Fact: I knew not of my crimes.
More important fact: I know now, but even though I know I’m playing with fire, there’s no way I’m stopping. I can’t leave her alone.

Question: What do you do when you fall for your best friend’s little sister?
More important question: How long can you keep it a secret before it all goes up in flames?

Disclaimer: The Billionaire’s Forbidden Little Sister is a romantic comedy, NOT a taboo romance. We repeat: It is NOT about a billionaire canoodling with his own sister. However, if you find yourself wishing it were, we suggest switching around some names to make it so. We can’t guarantee it won’t be confusing at times, but who knows? It could be just what your doctor ordered.

Lena and Theo.

Theo is one of the guys from the hilarious Billionaire Book Club!
(You know the one? Cap and Kline and THATCH are other members you might know! LOL)

Theo is a kid from a rich hotel family, but he made his own empire - he's running super successful clubs worldwide. He's just now on his way to Italy for another grand opening.

description

Lena is the sister of ... CAP!

She's in Milan for the year to study fashion. And this weekend she's celebrating with a few friends at this club on the italian Amalfi coast.

Obviously they will be in Theo's club. And of course our two darlings will meet.
It's insta über-attraction on both sides.

But can it be more than an amazingly sexy & fun week-long fling?

Theo doesn't date and Lena is kind of on a man ban.

Plus also - no one yet knows that Cap is the big brother in this scenario - and you know you never start something with your buddy's little sis!

LET THE FUN TIMES BEGIN!

ADORABLE!!!


I just adored this story!

The first half is this hilarious and sexy and sunny vacation fling adventure in Italy. And then we go back home to New York, where we're trying to keep everything from poor Cap.

I loved reading this.

I adored Theo and Lena! And Theo's asisstant and Theo's grandpa and Lena's british friend are so effing über-hilarious! I need a spin-off with ALLL the people! LOL!

And of course we get lots of Cap and Thatch et cetera. How can you not love such a book!?
(P.S. should you not know who Thatch is - you've obviously been asleep these last few years and need to hurry to amazon and get started with Max Monroe's first amazing Billionaire Bad Boy series!)

AMAZING ROMANTIC COMEDY!

How is it possible that none of Max Monroe's books are streaming their behinds off on Netflix yet??? The world is weird!

I didn't love-love the way Lena reacts after Italy and towards the end of the book to what her mother says. All a bit immature and silly - but also a little understandable.

THE BILLIONAIRE'S FORBIDDEN LITTLE SISTER was such a hilarious & adorable & sunny & sexy Italy & New York Rom-Com! Hurry to your nearest amazon for your own Theo - he'll be sold out in no time!

Cute.

Cute fling to lovers romance. It’s also clearly best friend’s little sister romance as well, but that felt like a blip in this story. It’s more about two people who aren’t looking for strings, have a fling, and then unexpectedly want some strings. But then the strings get string-y and they have some bumps in the road. That was probably all confusing, but I enjoyed Theo & Lena’s story. It was steamy, fun, and honestly an easy read.

Five rendezvous stars Lena and Theo 💖!!!

🌟🌟🌟🌟🌟

Max Monroe never disappoints!

I was waiting for Lena's story since I've read The Billionaire Best Friend.

And it was worth waiting.

"The Billionaire's Forbidden Little Sister" is a witty romance story that will make you laugh on every single page.

Lena and Theo's relationship started as secret rendezvous but what it became was one explosive, beautiful and sweet love story.

If you're looking for a fun romantic comedy book that will make to enjoy trough the whole book, then this one is definitely for you!

I really don't know how to rate this. On the one hand, I enjoyed it a lot and I really liked the main characters (especially Lena, I loved how confident she was) and their story so I'm tempted to give it 4 stars.

On the other hand, I still can't figure out how many friends Theo had and how everyone was related to each other, I just got lost. Also, I probably couldn't remember half of the side characters' names because they were so many of them.

And I kinda hate the cover 😬

I don't use .5 stars but this is one of the cases that make me think I should. Mostly 3.5 stars rounded down.

Reading The Billionaire's Forbidden Little Sister was like watching a TV with a bored panda sitting on you with a remote control. There was some shitshow on and you couldn't do anything about it, unless you dared to enrage the panda.

It is clear to see by all my highlights that I liked this book. I have said it before and I am sure I will continue to say it……Max Monroe books are written for me. They really are the perfect SEXY RomComs.

I loved that these two characters did not know who they were spending time with when they hooked up.

Lena is on vacation with her classmates celebrating the end of design school before starting her internship. She has been on a sabbatical from men for like 8 to 9 months…..the entire time she has been in designer school. She wants nothing to distract her from her goals but decides maybe a vacation fling before she gets down to business is just what she needs.

Theo runs the family business, which is high end resorts and night clubs and he is a workaholic. His Billionaire Book Club buddies are pressuring him to live a little by hooking up with anyone while in Italy on business. Little does he know the American beauty he meets is none other than Caplin Hawkins little sister.

The supporting characters as always are fabulous. Carey is the best, Pippa is hilarious and of course all the previous characters from the other books in this series.

The book is funny, interesting, frustrating (mainly because of Lena’s mother) and Sensual!

4 Mr. Serious Stars

This book was a light hearted, OTT, charmer! I really liked both MC’s, and the laughs were a plenty! There were also many scenes with some old favorite characters from the “Billionaire Bad Boys,” series. Despite some of the silliness, and predictability, the hilarity won me over! This one has been my favorite in the series, thus far!

The Billionaire's Forbidden Little Sister is seriously one of the most funniest books I have read thus year. When I say I was die hard laughing from the Prologue until the Epilogue, I mean that with every fiber of my being. It has the perfect blend of, fine a** billionaires, sassy as all get out heroines, a book club to beat all book clubs, and a story line that goes unmatched. This sinfully sweet, hilarious Rom-Com is nothing but a good time.

This duo of authors and their wicked writing skills, kept me under their spell when it came to Lena and Theo's story. From the blistering chemistry, that could easily set the sheets aflame, to the hysterical references that only Max and Monroe could conjure, I just could NOT get enough. It was amazing to see these main characters open their wings and fly, to learn not to be so strapped by their professional lives, and for them to experience a personal life with amazingly supportive friends and family. It made the progression of their story fly by to me. The Billionaire's Forbidden Little Sister flowed so naturally, that when the ending came I was like, " Wait, how did that happen''? Ladies and gentlemen, that is perfection at it's finest, two characters at their finest. Lena and Theo's story goes down in the record books as one of my top two favorite books by these authors.

* I RECOMMEND THIS BOOK

I haven’t laughed that hard in a LONG time. Those book club scenes had me almost peeing my pants. And the scenes with Theo and his gay and fabulous assistant Carey, were the BEST.

Some other new great characters....Pippa (Lena’s English friend from Italy) and Brogan (Theo’s eccentric older brother). They were a part of the scenes that contributed to all the LOL moments.

Now the H/h. I honestly don’t remember Theo from the other books. I do remember Lena. She’s Cap’s little sister and Maybe’s bff. She’s a free spirit with a bohemian vibe (or that’s how she was described in Maybe’s book. Here not so much). She’s wild and crazy. Free of inhibitions. The complete opposite of Theo. Who’s “Mr. Serious” and works too much. He has a few women he rotates in his calendar for booty calls and he doesn’t have time for a relationship. Until he meets Lena of course.

I have to be honest, I didn’t expect Lena’s character to be so cowardly and annoying. There are 2 times in the book where I wanted to slap her upside the head. Theo is steadfast the entire time. Never wavering in his feelings.

Super funny, LOTS of hot sexy times, and great characters.

I’m realllllllllly hoping we get a novella for Cap and Ruby’s wedding.

What happens when one sassy, sweet woman meets a gorgeous billionaire while in a foreign country? Why, a hot little romp of course! Then what happens when that woman turns out to be said billionaire's best friend's little sister? Some definite oops!

TBFLS - Teaser 5 AN

I swear, Max Monroes' rom-coms keep getting funnier and sexier and even better with every release because Theo and Lena are FIRE!! I loved everything about these two together. And did I mention the cameos by Cap and gang? Yep. And they made the story that much better because everything is better when this crew is together.

Holy hotness people..... this was one book filled with explosive chemistry from beginning to end. Theo and Lena were two people not looking for anything long term. What happens when you find something so unexpected in the one person you shouldn't? This book was equal parts hilarious, sexy, fun and flirty that I devoured the story in a day. I have fallen in love with these characters and you will too!

5 SMOOCHES!

I absolutely love romantic comedies, they’re at the top of the list of my favorite things to read, and a Max Monroe romantic comedy is a special kind of reading experience for me. What makes their romcoms stand outs in the genre is that while they are wildly hilarious, if the authors were to strip the humor from the story, there would still be a solidly engaging, steamy romance there that could stand on its own. That is a testament to the creativity of this author duo, and speaks volumes about the quality of their writing. I truly hope the authors don’t do that, though, because I really fluffing love their uniquely comical sense of humor. Imaginative plots coupled with endearing characters embroiled in these deliciously sexy romances that are heart-tugging and heart-warming, and this is romantic comedy perfection on the page. I can always count on Max Monroe to give me an unputdownable, audible-laugh-inducing, feel-good romance, and it’s what drives me to pick up their books time and time again.

The Billionaire’s Forbidden Little Sister was totally up my alley—I loved everything about it. The brother’s best friend/best friend’s little sister trope is a personal favorite of mine, and Max Monroe penned an absolute winner here. Theo and Lena were magic together. She breathed life into this incredibly focused, schedule-driven billionaire, and he was the steadying, stable force she needed. Their relationship was all about the balance, and shenanigans aside, these two were perfectly paired. Add in a splash of drama that only Caplin Hawkins, Lena’s big brother and one of Theo’s billionaire best buddies, and this story was an entertaining, amusing, passionate page-turner.

An utterly charming blend of sweet, sexy romance and laugh-out-loud humor, The Billionaire’s Forbidden Little Sister is exactly what readers crave from this author. Fantastically well executed, light-hearted and fun, I smiled from ear-to-ear the whole way through as I practically inhaled this book. Five smooches from me for The Billionaire’s Forbidden Little Sister by Max Monroe!

5 star review The Billionaires Forbidden Little Sister by Max Monroe

What happens when a smoking hot rendezvous with a beautiful stranger turns out that the woman in question is the little sister of one of your closest friends Caplin Hawkins. This is the position that Theo Cruz finds himself in when he falls for Lena.

The Billionaires Forbidden Little Sister brought a much needed smile and laugh to me this week. From the first to the last page I was totally invested in Theo and Lena’s story. The chemistry between them is intense and so smoking hot I almost needed a fan.

The appearance of some familiar faces is always fun and in this case made for complications. I loved the predicament that Theo is in when he tries to keep his blossoming relationship with Lena a secret. Oh what a tangles web we weave…

I absolutely loved everything about Theo and Lena, both separately and especially together, what a terrific pairing they make. I particularly enjoyed how work focused Theo, slowly realized that there was so much more to life and that the feisty and sassy Lena was able to show him the light. The fact that neither Theo or Lena ever had the time to fall in love just added to my satisfaction when they did.

This was a laugh out loud, hilarious read that had me receiving many funny looks as I was reading; in fact I was actually snort laughing which made it even worse. It was non stop fun and all I can say is please write more stories with these amazing characters.

Another fabulous book Max Monroe, you two nail the RomCom genre and set a very high bar for others. The Billionaires Forbidden Little Sister is one of the funniest books I have read this year and I cannot wait to listen to it on audio.

Oh my gosh, this book was sooo darn good!! It’s hilarious, lighthearted, fun and charming, and exactly what I needed! This is now my favorite Max Monroe book and they’re all fantastic! It’s the fourth book in the Billionaire series, yet still a standalone. It follows Lena and Theo, who we have seen in previous books.

Theo and Lena meet in Italy in some unusual circumstances. The locations and scenes here were so detailed and amazing! Their meet cute was the best. The banter was so fun! They have a brief fling in Italy and both leave without knowing any personal information about each other. So, imagine their surprise, when it turns out she’s the little sister of his best friend, Caplin! All the characters are wonderful, even secondary ones. Get ready to laugh about Grandpa Merl and Pippa! I laughed so hard at their antics! We do see every one of our favorite Billionaire couples and the boys were at their usual shenanigans. There’s just so much to love about this book. I adored this fun romantic comedy and I highly recommend it!!

4.5 stars!

Lena is Cap’s sister and from the moment I met her in The Billionaire Book Club  I was excited for her story. She’s fun, flirty, and, sexy and has no trouble getting a guy. However, they only seem to distract her so she goes on a man ban so she can focus on her dreams. She has stuck with it for months but now that her friend wants to go out and party to celebrate the holidays, she lifts the ban for one night only.

Theo is a successful business man who is a bit of a control freak and has every minute of every day planned out. He doesn’t have time for relationships working 80+ hours a week growing his very successful business, Cruz Nightlife. He heads to the Amalfi coast for his grand opening of Club Indigo in Positano.  He wasn’t planning on hooking up with anyone but when a gorgeous woman catches his attention, he decides a little casual fun can’t hurt.
She is sex and sin and lust and seduction all rolled into one, and I have never felt more present in a moment than I do in this one.
Normally, my brain is going a mile a minute, obsessed with work, planning and plotting and always looking five steps ahead to the future.
But not right now. Not here. Not with her.
Right now, I’m a man dancing with a woman—one who screams trouble and spontaneity and wild, passionate sex.

Theo and Lena have a week long rendezvous that turns out to be the best week of their lives. They connect. They have fun. They turn up the heat and they don’t want to let go. But at the end of the week they part ways with only first names and unforgettable memories to take with them.

I love brother's best friend/forbidden romance storylines and I thought this one was really well done. Well-paced and full of humor, heart, and a whole lot of heat, it was easy to get sucked into the story. Theo and Lena clicked immediately and I felt their connection. Their easy banter is entertaining and the smoking hot chemistry is believable. I felt every heated glance, every seductive touch, and every moment that these two fell a little harder.
“You don’t ever do first and think later?”
I shake my head. “Never.”
“Really?”
I nod. “Really.”
“So, you really are Mr. Serious, huh?”
“I guess so,” I say with a shrug.
She studies me closely. “You’ve sure been smiling a lot at me, though.”
I laugh, completely entranced by just how true a statement that is. “I know.” I shake my head. “Trust me, I know.”

I loved them the first time they spent time together but I fell for them harder the second time around. It’s hilarious when these two meet again. A total surprise, they don’t know quite what to do about it.  Finding their way back to each other while navigating a forbidden relationship since Cap would never approve made things more intense and exciting. They consume each other and have no trouble taking risks to be together.
We’ve gone mad. Insane. We’re playing with fire right now, but fuck if I’m looking for water to put out the flames.

I loved how Lena and Theo's love story unfolded and I couldn't get enough of them. They are sweet characters to adore and I am so glad we got another wonderful billionaire romance!

And the rest of the billionaires who make an appearance? They are still awesome and every interaction is fantastic. I can’t even think up the stuff that comes out of their mouths and I love it all. I look forward to getting more glimpses into all of their lives when the next Billioniare Collection book releases!!

Max and Monroe can do no wrong in my eyes, especially when it comes to this series. Yes, I've rated them all 5 stars and they are all so fluffing brilliant, if someone tells you otherwise they are filthy liars.

Gosh, where to start? In the previous books, Theo was the kind of secondary character who had some witty punchlines but was in the background most of the time. Honestly, until now I could barely remember his name.
But now... Damn, ladies, you NEED to get to know him better. You know, the workaholic businessman type with the panty-melting smile and dirty mouth who's quick to fall for the crazy kind. Yep, pull the fire alarm.

Theo is in Italy on a business trip when he spots the beautiful blonde at the bar of his newest club. Very unlike him, but he makes his move and after a little persuasion and two nights of drunken cockblocking from an alcohol virgin Brit, he finally gets the mysterious Lena all to himself for a few amazing days.
Lena's been on a very strict man ban, as she calls it. She feels like she's made nothing of her life yet and wants to prove to her family that she finally found something that she's serious and passionate about. While focusing on her fashion designs and school, men weren't allowed distractions. Until she meets Theo, Mr. Serious with a rare but the best smile she's ever seen. The ban is lifted for a few days until she has to go back to the States but their Italian Rendezvous comes with a few rules.
When their days together are over though, emotions neither of them wants to acknowledge are involved so Lena does what she thinks is best and leaves without saying goodbye. Or a phone number. Or her last name.
Fast forward a few weeks, they are still on each other's minds when Cap - yes, the crazy Cap-i-tain - drags Theo to Fashion Week and introduces him to his sister, Lena. Yes, the very same.
See where I'm going with this?
Obviously the attraction is still there and they are quick to give in and act on it before they both go crazy. But of course, there's Cap and the fact that he's said a thousand times before, his little sister is forbidden. He might be a bit crazy but also a hell of a lawyer who can smell bullshit from a hundred miles.

Anyhoo, I'm sure you think the storyline is something you've read about a dozen times before, but trust me, the way Max and Monroe write a story, no one else can. It was hilarious, so witty and hot as all f#cks. Not to mention that in every book we get pieces of the whole bunch we've come to love.
I need it in writing that this series never ends, thank you very much.

3.75 stars. This was a cute and fun book! The Billionaire's Forbidden Little Sister is Lena (Caplin's little sister) and Theo's story. Lena is in Italy for fashion school when she meets Theo, who is there on work. The two have an instant connection and chemistry. They agree to no names or details between them as they have an Italian fling for a week. Lena has some insecurities about her past flightiness, so she wants to focus on finishing school and beginning her career in the fashion industry, without a relationship to complicate things. But both of them develop feelings for each other and regret leaving each other behind with no way to contact each other after their week together. When they run into each other again back home in NYC, Theo discovers that Lena is Cap's little sister. They both missed each other and want to continue their relationship, but are afraid of Cap's reaction as he is overprotective of Lena. So they have some issues to work through, but they fall for each other anyway and get their HEA.

This story was really cute. I liked Theo and Lena both. Theo was all work, no play, and Lena was the impulsive, breath of fresh air he needed to liven up his life. They made a great match and were sexy and sweet together. I did feel like the climax/conflict was a little manufactured and forced. But, besides that, I really enjoyed this book. I was glad it was not quite as silly humored as some of the other books in this series.

Overall, The Billionaire's Forbidden Little Sister is an entertaining, low angst, sweet, funny, cute, and safe rom-com. I enjoyed Theo and Lena's story and look forward to more from Max Monroe in the future!

The boys are back with their Billionaire Book Club! This book is Theo’s and Lena’s story. Lena is Cap’s little sister and a relationship between them is completely forbidden. Although the title would say otherwise the forbidden part of the storyline was a very small part as these two hook up for a week of passion in Italy and then go their separate ways. Once they return to their lives the two cannot stop thinking about another until they bump into each other again unexpectedly and realize they are only living 20 minutes apart. There was a lot of push and pull and a lot of steamy moments and scenes that will have you laughing out loud one moment and swooning the next. It is signature Max Monroe and I enjoyed it a lot. 4 STARS.

NO SPOILERS!

Max Monroe delivered all the laughs, all the feels, and pure romantic comedy PERFECTION with The Billionaire’s Forbidden Little Sister! I absolutely LOVED Theo and Lena’s sexy, hilarious, swoon-worthy, and highly entertaining story. It made me laugh, smile, and swoon like a fool, and I freaking loved every minute of it.

The storyline and characters were beyond phenomenal, and I once again loved and adored Max Monroe’s writing style and flipping hilarious sense of humor. These two ladies make romantic comedy seem effortless, and they never fail to deliver amazing, MUST READ love stories.

Theo and Lena’s story in The Billionaire’s Forbidden Little Sister has been one of my favorite standalones in the Billionaire Collection thus far, and I can’t wait to devour more romcoms from this MUST READ author duo!

Lena was raised in a privileged lifestyle but she is determined to follow her own dreams and not give into the pressure that is being levied by one parent in particular. She has been studying fashion in Italy for the last nine months and is will be heading back to the US soon. Now that her studies have come to a close her friends have convinced her to have some fun before that happens and Theo is the perfect man for the job.

Theo was attracted to Lena the moment he saw her and after a few false starts the chemistry between them ignites. They both know that this will be nothing more than a fling as they are both destined to go their own ways so sharing information about each other is off limits.

Now that Theo has returned home the surprise is on both him and Lena when they realize their fling didn’t stay in Italy as she is Cap’s little sister and Cap happens to be Theo’s best friend. They know they should stay away from each other but that is easier said than done and that is when the fun really begins!

Fun and flirty not only do we get to watch the relationship between Theo and Lena unfold but we also get to catch up with all the other characters that we know and love.

The Billionaire's Forbidden Little Sister is a stand-alone book by Max Monroe. It's connected to some of their other recent releases, but if I hadn't told you that (or you knew because you are a fan of the authors) you wouldn't have noticed.

I hate to say this, but the book didn't work for me as much as I wanted it to. I found it hard to finish for some reason, even though none of my pet peeves were included and I love Max Monroe's books. There was something that made me feel a little awkward when it came to Theo and Lena been together and they didn't click for me as a couple.

I am a little disappointed with this release and it makes me sad because I usually enjoy the books written by this duo and I have no trouble finishing them even if I find their humor a little extreme. I am looking at you, The Billionaire Book Club. Maybe it was just me and my book funk.

The Billionaire's Forbidden Little Sister by Max Monroe is the story of Theo and Lena. If you read the previous book 'The Billionaire Book Club' then you will see some of the previous characters in this book. Lena is the sister to Caplin and Theo is of course Caplin's friend. So with that said this can be a standalone book but just wanted to point that out if you enjoyed that book you might want to continue the love with this book. This is a funny romance story where Lena is in Milan for a year to study fashion and Theo is there for one of his newer clubs. That just happen to meet and of course the sparks flew through them which made it hard for them to turn away from that feeling.
Fun and easy read!

In the Billionaire’s world created by Max Monroe, the heroes are loud with no filter, with their big hearts, having now weekly book clubs sessions, working hard and finding their match in some unexpected ways.

As part of the last two bachelors of the group, Theo was having no issues to be married to his job, even with women every minute counted, no time wasted, until his trip to Italy. Until he finally met his match not really knowing who she was. Because being abroad with that tempting siren and all her rules to keep it just in the moment felt right. But not for long.

I enjoyed a lot Lena and Theo’s story. She was the wild side that made him want more things, being more spontaneous. They were a great match for sure. It was less crazier than the other books but still hilarious, swoony, smoking hot and definitely a bit naughty!

I appreciated the instant connection and chemistry between the two, how natural they were together. The built up of the relationship was great, going with the ups and downs, insecurities. I liked how work driven they were, achieving their dreams and trying to find a certain balance in their lives. 

I was curious about Theo who seemed to be more secretive than his other friends, obtrusive and a bit mysterious. Watching that man falling in love was so interesting. Especially about his best friend’s little sister. Not the guy her brother and also his best friend, Cap would have suspected.

Theo and Lena were great together, the chemistry was off the charts. The supportive and crazy characters added a bit of madness. I adored how everything melt perfectly. Somehow I felt like the issues and drama between them felt a little forced. 

But still, I enjoyed reading it! The whole thing was entertaining and hilarious with a hint of sweetness. I can’t wait for the last one to meet his match.
