Maiden Voyage by Jamie K. Schmidt

Former Coast Guard captain, Meryl Sinclair is excited for the first voyage of Castellon Cruise’s newest ship, Heart of the Sea.
However when her second in command gets thrown in jail the night before they set sail, the company sends a replacement.
Rafael Castellon is the owner’s son and he’s pissed that he wasn’t promoted to captain of the new ship.
Rafael and she have a past. A sun-drenched past of sex and debauchery. And he had no idea that she worked for his father. Surprise!
When their passion takes over, a week-long fling seems like a good idea. Except there are people who don’t think a woman should be captain of a cruise line. And Meryl’s not sure if her lover is one of them or not.
Meanwhile, a passenger looks to say goodbye to an old friend, and perhaps find a deeper relationship with a kind stranger.
