Sin at Sea by Emma Nichols

When Alysin decided to surprise her boyfriend at work with dinner, the surprise was on her. Since he was going at it with his secretary on the conference table, she packed a bag and called her BFF. Jolie and Alysin had been traveling the country, working as digital nomads for ten years ever since graduation. Taking this as a sign it was time for a new move, they decided to take a cruise, regroup, and make a plan.

Then she meets Mr. Bedroom Eyes. Following her lead, they pretend to be married so that she can rid herself of the guy who started hitting on her before the boat left the dock. Though it was supposed to be a momentary arrangement, he asks her to take it one step farther. Then another and another. The cruise promises to be memorable in every way that matters.

Along the way, Alysin learns that she won't have to fake an orgasm if she's with someone who knows what to do, that not all men suck, but the best ones suck really well, and that sometimes what starts out as something pretend, can fast become something completely real. Will the woman who lives life with no regrets, regret that she made that stupid rule about not exchanging names and contact info?
