Last Resort: A billionaire, forced proximity, destination, one night stand, workplace romance (The S.I.N. Series (The Sharpe Brothers) Book 1) Kindle Edition
I was never supposed to see him again. Him being the man wearing the perfectly tailored suit who oozed an intoxicating mixture of wealth, rebellion, and sex appeal.
One night.
No strings.
No names.
Great sex.
Still riding the high from last night, I walk in to meet my new client, and he’s wearing that same dangerous smirk that reeled me in hours ago.
Yes, I’m consulting for Callahan Sharpe. And yes, he’s that Callahan Sharpe.
Billionaire heir apparent who abides by no rules, bucks convention, and is determined to complete one final project to honor his late father’s legacy before walking away from the family business for good. Luckily and unluckily for me, I’ve been tasked to go to the Virgin Islands to help accomplish his goal. Callahan has no problem breaking his company’s no fraternization rule, but not me. There’s too much at stake.
What could possibly go wrong when you’re forced to work—and live—side by side with a man you can’t resist?
Are you ready to fall for the Sharpe brothers in K. Bromberg's sexy, contemporary, billionaire romance series? These books can all be read as standalones, but can be enjoyed as a series as well . . .

About the author

New York Times Bestselling author K. Bromberg writes contemporary romance novels that contain a mixture of sweet, emotional, a whole lot of sexy, and a little bit of real. She likes to write strong heroines and damaged heroes, who we love to hate but can’t help to love.
A mom of three, she plots her novels in between school runs, sports practices, and figuring out how to navigate parenting teenagers (send more wine!). More often than not, she does all of this with her laptop in tow, and her mind daydreaming of the current hero she is writing.
Since publishing her first book on a whim in 2013, Kristy has sold over two million copies of her books across twenty different countries and has landed on the New York Times, USA Today, and Wall Street Journal Bestsellers lists over thirty times. Her Driven trilogy has been adapted for film and is available on the streaming platform Passionflix as well as Amazon.
You can find out more about Kristy, her books, or just chat with her on any of her social media accounts. The easiest way to stay up to date on new releases and upcoming novels is to sign up for her newsletter or follow her on Bookbub.

- Reviewed in the United States on April 2, 2022Format: KindleVerified Purchase"Oh fu..." (and a little gasp) was my reaction to the first chapter, and I immediately knew that I was going to be in for a devourable read, the kind where you sit back and enjoy the show. And this is definitely that. I binged this in one sitting with zero regrets - the story is tense, chemistry-filled, and like a sexy cat and mouse chase. It's a SIZZLE to slow burn, in that this couple starts with a HOT one night stand before discovering that they'll be working together. I loved that the emotional connection built slow and steady throughout the story, with our playboy hero off-balance the entire time. He's never had to work hard for a girl, but he finds himself drawn to the heroine in a way that's undeniable. It reads quickly, easily held my attention the whole way through, and has me very very excited for future interconnected standalones in the series.
The story follows Sutton, a woman who realizes that she's been putting her own needs after her boyfriend's. When she finally does one thing for herself - accept a promotion - it's the end of that relationship. On the rebound, Sutton meets a sexy stranger at a bar and soon finds herself going up to his room. They both know they'll have one night only, no names are exchanged, and the night makes Sutton feel empowered... until she walks into a meeting the next day and sees the man she just spent the night with. Well... three of him. Turns out, that sexy stranger is a triplet who runs a business with his brothers, and Sutton has just been tasked with consulting on a project. As the chemistry continues to spark between Sutton and her one night stand, she realizes that the dynamic needs to change. There's no way she'll be respected professionally if she knowingly sleeps with the boss, but denying the chemistry is impossible.
Bromberg is an easy one-click author for me, so I was excited to dig into this new series and see what it's all about. The vibe reminded me of the Wicked Ways duet (my favorite from her), with a ZAP of connection, tons of banter, a slow build in intimacy, and heated moments in nearly every interaction. Each book will follow one of the triplets, and I can't wait to get to know the other two better. This made quite the first impression, wasting zero time getting right into the action. I loved the intensity of that first steamy scene, and it certainly cemented the chemistry between these two. Our hero doesn't know how to handle what he's feeling, and watching him struggle was so much fun. He undergoes a great transformation throughout the book, making their happily ever after fulfilling. The subtle shifts in their relationship kept this feeling tense and sexy for most of the story - entirely bingeable and compelling.
Audio note: The audio was excellent! Stella Hunter and Aaron Shedlock both do a great job, with performances that showcase the chemistry and emotion. Their voices are both easy to listen to, the overall quality is solid, and the dual narration enhanced the reading experience. The runtime is under 8 hours, so it's easy to finish in one day (or one sitting, if you're like me, lol). Not necessarily a book that I would recommend for a workday listen - the heat starts quickly, and there are sexually charged interactions throughout. But this was a really good audio experience, and I wholeheartedly recommend it.
- Reviewed in the United States on July 8, 2025Format: KindleVerified PurchaseThis might have been the last resort for Callahan but I believe he found he’s true meaning of life and where he belongs within his brothers. Sutton found herself and learned how to be a strong woman with a man’s support. Great book.
- Reviewed in the United States on November 1, 2023Format: KindleVerified PurchaseI had to take a moment, to give this review the utmost respect and justice it deserves. The story too. I purchased this book on 3/29/22 and I literally could punch myself for just now reading it. And for that I apologize.
But this was THE ABSOLUTE BEST BOOK I've read in 2023. The bar is set very high. I see now the reasoning behind the book's name. I'm a sap. I lost count at how many times I either teared up or flat out cried. Especially in the last few chapters. I know Kristy's book are good like that. I cried when Johnny (Callahan) said "me". I cried when Collins (Sutton) asked to herself, to go with Callahan. I cried when Callahan said he did, dad...thought to himself about bringing someone he loved to Ocean's Edge. I cried when wishes of spreading their wings to fly. The rocks. And the reason to have Callahan grow and make something of himself. Dad believed in him and wanted to see him succeed. "What's in it for me". Sutton and Callahan were THE couple.
The things that made me smile were the box of underwear, negotiations and brownies. The Starbucks. He didn't forget.
I fell in love with both Callahan and Sutton. Their interactions were definitely sexually tormented. And I loved them both. Sutton definitely made Callahan work for it and he had no clue. Sutton was a strong h and I loved her. She really knew how to shake her hips (so to speak) to really get Callahan to notice. And to really speak to him. Callahan learned how to speak to Sutton, like the strong, fantastic woman she was. And he really made an effort. She was the "one". She made an impression on him. Clint (ex-boyfriend) made her rethink her life. I was in her position not long ago where I was drowning in a relationship of 27 years that was leaving me wanting. My divorce allowed me to find myself. Sometimes things happen in our lives that forces us to repair our selves. And sometimes we don't know it until we are faced with it.
I'll take Sutton's words to heart when she liked her new life.
I don't think I'll ever forget the way I feel right now, when I think about his book. It has left me with my heart full and I feel so utterly satisfied. I don't think I could recommend this book any more than my words speaking. Thank you. Absolute perfection.
- Reviewed in the United States on March 25, 2025Format: KindleVerified PurchaseI usually expect the "Template" with romance stories. Here's the template, you'll see it everywhere. "Buff billionaire meets poor shop girl, can't stop lusting over her. They fall in love, then out of love, and finally get back together forever."
Yeah, there was a hint of the template, the difference being that this author can really write!
I was pleasantly surprised at how great the love story was.
My other metric on 'romance novels' claims the quality of the writing is inversely proportional to the amount of "steamy scenes". The better the writing, the fewer the 'steam'. This could use more, but there was enough to keep even the most die hard erotica fan happy.
Best of it's type.
- Reviewed in the United States on May 26, 2025Format: PaperbackVerified PurchaseThis was my first K. Bromberg book and I fell hard. I absolutely loved the dynamic between Callahan and Sutton. From the moment they met, there was real chemistry. I loved how this story had the FMC leave a toxic relationship and she chose to find herself and knew she deserved so much better. She was empowered and Callahan only helped to further her self-confidence. I'm looking forward to reading the rest of the series.

5.0 out of 5 stars Chance meetings can have lifetime consequences
Format: KindleVerified PurchaseA new series written by this great author, gives us three Sharpe brothers, and an empire. However although identical triplets that’s were their likenesses stop.Callahan has always been their late dad’s favourite, but possibly the black sheep. A chance encounter with Sutton in a night club leads to a really delicious story. She has decided at long last to leave her long time boyfriend Clint, who loves to humiliate her, keep her in check, so that his own ego is boosted. Lizzy her best friend encourages her to walk away and live. Sutton is not a one night stand , butCallahan doesn’t do relationships . Just one nightstands. They both finish up at the same place. To remodel a failing new enterprise that the Sharpe’s Dad purchased before his death. Only Callahan knows why. No more details just to say it’s a wonderful story, full of emotions, uncertainty, sibling rivalry, and romantic moments that are to curling. Humour abounds as do believable characters. Ledger and Ford are the other brothers, and I’m sure with each book in this trilogy they will have the time to shine.

5.0 out of 5 stars Hot and steamy, yet strong and beautiful!
Format: KindleVerified PurchaseLoved this story so much. The dark seriousness of Callaghan to the soft yet strong demeanour of Sutton worked beautifully together. Such a beautiful loving story built from some serious and hard a life events. These two were on fire together yet so loving at the same time. The way that they complimented one another melded perfectly. Such an incredible love story! A must read! I can’t wait for the next stories ❤️❤️❤️
