Easton Crawford put his modeling career and good looks before his marriage until it was over. Years later, he is finally learning how to be the father his daughter needed him to be. He's not looking for a new mom for his daughter—just nightly casual hook-ups. When his best friend, Avery, convinces him that a good way to meet a lot of single women is to go on a single's cruise, Easton finds more than just a hook-up when he meets a fellow cruiser, Brooke.

Brooke Bradley has taken care of her younger sister, Bailee, for most of their lives. While their mother was enjoying not being a mother, Brooke became the adult in the household at thirteen. She had always taken care of the people in her life, especially her boyfriend, Jared. If it wasn't for Brooke, Jared wouldn't know how to function throughout the day.

When Brooke's best friend, Nicole, gives her a gift of going on a cruise without telling her that it's a single's cruise, will Brooke find someone willing to be her constant and finally leave Jared?

Brooke and Easton learn that people are brought into their lives for many reasons. Over time, they find out what those reasons are. Some are to be a temporary acquaintance while others are there for life.
