Declan McGillis has spent the last four years working on high end yachts, catering to the needs of rich people. Currently, he is the bosun on the Helios, in charge of maintaining the ship while it's at sea. In that time, he has formed some pretty negative impressions of the wealthy people who spend time on the ship. He is happy on the sea, and happier when clients aren't snapping demands left and right, but he'll put up with the demands in order to get a fat tip at the end of the trip. He also sets strict rules: no hooking up with the other crew, and no hooking up with the clients. 
 Mackenzie Armstrong is on the Helios in an attempt to relax away from work for a couple weeks, reconnect with her father, and maybe find a way to live in peace, if not harmony, with her spoiled, pampered stepmother and stepsister. 
 Declan and Mackenzie catch each other's eye early in the trip, but a few rocky missteps mean their interactions are antagonistic in the beginning. But despite the anger simmering between them, there is also attraction and they can't deny that there is definite chemistry swirling at sea. 
 I felt for Mackenzie through the whole book. She was in a rough place with her family, and saw things her father didn't want to see, which kept things tense between them when they used to be so close. At the same time she was also dealing with the back and forth from Declan while she just wanted to relax for a bit. 
 Declan was often frustrating with his self-sabotage and flip-flopping decisions. He had the making for a full on swoony hero, and he did eventually redeem himself, but during the time they were on the ship, he was epically frustrating to read. 
 This was a fun, summery read that left me wishing I was on a cruise ship myself, on a beach somewhere, or at least poolside with the sun shining down. The side characters kept things grounded while adding humor to the situations these two find themselves. I loved both Ben and Brooke and the support they offered to Declan and Mackenzie. The epilogue had me smiling at how far this couple had come over the course of the book, and wrapped things up nicely while giving readers a glimpse at what had happened after the main plot was over. 
 I was gifted a copy in exchange for an honest review.
