Rules for Throuples #4

Rebound Rules: An MMF Vacation Romance

Rate this book
No matter how tempting they are, Gemma can’t possibly give in… Can she?
You might be wondering how a smart, professional woman could accidentally end up stuck on a cruise with her ex-fiancé’s brother and best friend.
I know what you’re thinking, but it wasn’t about revenge. All it took was one case of non-returnable custom-labeled champagne, two well-meaning guys, and a bridesmaid who approved of their hijinks.
And before I knew it, I was sharing the most romantic luxury suite I’ve ever seen aboard an upscale Medeterranian cruise liner with two devastatingly sexy, completely off-limits guys.
But are they really off limits? I mean, my fiancé ditched me on a plane to Bali the night before our wedding. I don’t owe him any loyalty.
Nope, no. Not giving in to temptation.
Even if our suite has no walls and a see-through shower.
Even if the guys keep doing things that threaten to bring my filthiest fantasies to life.

Rebound Rules is Book 4 in the Husband’s Best Friend series. It's a steamy, MMF, rebound, Vacation erotic romance. Gemma is a smart and sassy girl who's fiancé, Jake, leaves her two days before her wedding. He sends his brother, Brian, to deliver the bad new. He, along with his friend Enzo, convince her to go on her honeymoon with them after she tries to give them the tickets. This was a completely over the top read with hot chemistry, lots of laughs, and a happy ending. Kristin always delivers a sexy read and this did not dissapoint. I loved it.

I adore this Rules series. This author writes characters who are completely lovable, interesting, humorous, and hot AF.

This book is no different. The 3 characters each have a broken place inside that they were either not aware of or had misidentified. Their shifting relationship leads to self-exploration and healing without getting bogged down in too much negativity.

It is a quick read that brings joy (and some intense steam in an ancient alley). The first kiss...fire.

I loved the depth of the characters.
It amazed me that so much of their personalities and backstories were able to be revealed.
Now, I want to date two wonderful guys! 🥰

'His proximity was making it hard to think, hard to remember why I was supposed to be the responsible one. The scent of his skin was intoxicating, warm and masculine and overwhelming. I found myself wondering what he'd taste like, whether his mouth would be as soft as it looked.
The thought spurred a surge of panic. This was exactly the kind of thinking that got me into trouble, the kind of impulse that led to bad decisions and complicated situations. I'd learned years ago that mixing attraction with friendship was a recipe for disaster. And Enzo was a walking disaster.'

I loved this book. The premise was a throupling I had to read. I loved Gemma, Enzo, and Brian. The story was fascinating from the start. Gemma was a sensible, calm, rational? minded person who did not react how anyone would imagine when she found out his brother and best friend that her fiancé ditched her two days before her wedding. She gave them the tickets to her Mediterranean cruise as she certainly wasn't going now and essentially shooed them away. While Brian wanted to help her and felt compelled to fix what his brother had done, Enzo recognized that the two of them would never be able to afford a three-week luxury cruise to all these amazing places and shouldn't let it go to waste. So they tried the next best thing- convince her to go with them. Gemma was surprised herself she didn't feel the devastation she should have- or much of anything.

This was such a fun read. Though they weren't a couple, you could feel the chemistry between Brian and Enzo in the way they bickered. Both attracted to the other- though don't admit it to themselves- and attracted to her. I liked the dynamic between them. Their chemistry together was fire! I also liked the banter. I loved the way feelings got involved and their relationship developed.

"But this... what we have... it's not casual. It's the most important thing that's ever happened to me."

I was so hooked to the story! A beautiful romance and now my favorite from Kristin Lance! 5 stars

Three people. One ruined wedding. A cruise that changes everything.

When Gemma’s fiancé Jake bails two days before their wedding, she doesn’t cry. She doesn’t scream. She hands the honeymoon tickets to his brother and best friend, telling them to go without her. But in a last-minute twist, she ends up on the ship with them, one suitcase, zero expectations, and no plan for what comes next.

Brian is the responsible older brother, all structure and self-control. Enzo is the reckless best friend, chaos in tattoos and charm. Gemma holds it all together, or at least pretends to. What begins as awkward politeness spirals into something else. Long looks. Confessions. Touches that linger. Secrets that surface. None of them are looking for more, but more is exactly what they find.

As the ship sails through Spain, Italy, and Morocco, boundaries start to bend. Brian’s quiet need meets Enzo’s restless craving for connection. Gemma lets herself feel. What starts as sexual exploration becomes something deeper, harder to define. They lean into each other and start to build something real, flawed, tender, and messy.

But as the cruise ends, choices have to be made, fears confronted, and they must claim the life they want.

Gemma evolves from a controlled, guarded woman into one who embraces vulnerability, pleasure, and connection. Enzo moves past his fear of rejection and embraces his bisexuality. Brian lets go of his rigid control and accepts his need for love and emotional safety. Their relationship grows into one of deep commitment, trust, and shared purpose.

A steamy, MMF, ménage, vacation romance exploring love, desire, healing, self-discovery, vulnerability, sexual exploration, polyamory, trust, chosen family, identity, and growth. It’s about rewriting what relationships look like and healing through intimacy. It’s about letting go of what should have been and holding on to what is.

REVIEW:

I liked this one. The travel vibe was really fun and laid back. I loved the atmosphere of adventure and relaxation.

All three characters were good too. Likable and sexy and they all had good chemistry together.

I can't say I'm wowed by it. It was good and I liked it, but I wasn't blown away or anything. I went into this series hoping for the stories to be mostly situations where the two guys were already best friends (like the first book in the series). So I'm kind of disappointed that's not the case.

Still, overall I did like it. It was fun and adventurous and sexy. I still plan to read on in the series.

4.5 stars. This story is triple POV, well written, and a sweet and spicy, contemporary, ménage a trois romance, featuring a jilted fiancée, Gemma, and her ex’s brother, Brian, and best friend, Enzo, who came to break the news her ex had run away. I enjoyed the contrast between Enzo’s charming, carefree presentation and his deeper anxieties and reservations contrasted with Brian’s stern, uptight presentation and his significant experience. I enjoyed Gemma’s willingness to take a chance. I enjoyed the way each character’s concerns and uncertainties were addressed with gentleness and consideration by the other partners. I especially enjoyed that this was a whole new relationship forming (others in the series have been a married couple adding a third partner). I enjoyed the erotic intimate scenes and the way those contributed to relationship development. I enjoyed the community that is forming in Gemma’s family with the triad relationships.

Author Kristin Lance usually warns readers that her books are high heat and “mostly smut,” and I think that sadly might keep some people away. Yes, her books are spicy, but despite the barely-there plots, I have always found her books to be extremely well written. The characters are always multi-layered and her writing style is so wonderful. Her books always move so smoothly from start to finish. Her latest, “Rebound Rules”, is no exception. Gemma is jilted by her no-good fiancé and ends up on a cruise with his brother and his brother’s best friend. I liked all three characters and thought they made a great triad. There was more than just “smut” to this story of three people finding each other and a love that lasts. Recommended.

This was a well written, sweet and spicy romance that brings our gal, Gemma, out of shock at being abandoned by her fiancé the night before her wedding, and puts her in the path of her ex's brother, Brian, and his bestie, Enzo. Sadly, these two were the ones that broke the news of her broken engagement to Gemma but their chemistry was hot and their connection instant and strong. I loved how Enzo was more on the playful side and Brian contrasted completely to him by being rather uptight and stern. There is some angst but there's also definitely a ton of hot spice ;P Of course, I love that the author gave Gemma the HEA she never expected but was thrilled to have. Good fun!

Gemma, it turns out, is even more controlled and workaholic than her cousin Tristan. When her fiancé bails out on her days before their wedding, she decides to gift their honeymoon cruise to her ex-fiancé’s brother (Brian) and best friend (Enzo). When they, with the help of Gemma’s bridesmaid and a case of champagne, ‘kidnap’ her, the simmering looks between them turns into some very hot, and sometimes public action. This centred more on Brian, who despite his boring name and boring profession turns out to have a very hight sex drive with the long list of faceless encounters to match. He was maybe a bit too dominating for me but still loving this series.

Yes, I love this book. Granted, it's incredibly steamy and entirely out of the box, but it's a fantastic escape. Gemma is dumped two days before her wedding. Brian, the brother of the groom, accompanied by Enzo, breaks the news to her and convinces her to take the honeymoon trip with them. And this is the perfect storm coming together. These three — Brian, Enzo, and Gemma — fit together so perfectly. I love their story and the happy ending that they get. Excellent book!

Seductive and steamy and set against some gorgeous backdrops as this throuple travel around the Mediterranean. I loved how the stereotypical personalities were thrown away in this story and how these three came to love one another deeply and passionately in three short weeks given the circumstances of how they are thrown together. I also adored the epilogue where you see where the three throuple's from this series all end up and how they've all flourished.

One Steamy Cruise

Two days before her wedding, Gemma is stood up. The non-groom’s brother Brian and best friend Enzo break the news … and then they all end up on the cruise together, where lingering glances become steamy looks. Wooo-wee this book is red hot and steamy! Beautiful Mediterranean backdrops make for the perfect places to get up close and personal…a fan and a cool drink are highly recommended! I loved this book, really this whole series, and these three were something special. A magnificent read.

I love the books in this series by Kristin Lance and I swear they just get better and better. This one find Gemma, Enzo, and Brian on a un-honeymoon cruise where secrets are revealed, swords cross, and Gemma finds her first "O". I love how they find their HEA where 3 is better than 2. What a wonderful read!.

Rebound Rules: An MMF Vacation Romance is Book 4 of the Husband’s Best Friend series by Kristin Lance. This was a seriously heavily spiced book that might have used some ghost peppers. Plot? Not so much, but it does have a happy ending.

I received a free copy of this book via Booksprout and am voluntarily leaving a review. I liked how Enzo and Brian help Gemma enjoy the cruise. Gemma was dumped just before her wedding but I don't think she cared too much. I liked how the three developed a relationship and fell in love. I'm glad they found a way to continue after the cruise.

Gemma's ex-fiance may be Enzo's best friend and Brian's brother but they had no idea he was ditching his bride-to-be mere days before their wedding. A sexy and sizzling read as the three get to know each other intimately on the cruise of a lifetime.

✨✨✨Unconventional love for the win✨✨✨

What happens when 3 completely different people meet and uncover connections they never thought were possible. Gemma who appeared like a cold statue to Brian who was closed off from any love to Enzo who was never serious about anything. Read this to find out how they turn everything into the best love story of modern times.

She got caught up in a cruise romance with her ex-fiancé’s brother and his best friend. The night. Before her wedding her man takes off. Now she is a free woman, so why not have a lot of rebound fun.

I stumbled across this series and I’m so glad I did! Sweet and very steamy with likeable characters and a solid and heartwarming plot line. Notably, the story doesn’t feel repetitive and doesn’t drag, which are so common in this genre.
