A ten-day Caribbean cruise might sound like a fabulous way to spend the holidays, but Liz would rather be anywhere than stranded on a ship with her estranged father for his high school reunion. While an anonymous note, an onboard mystery, and a cute boy help turn the tide on the unwanted trip, Liz and her father drift even further apart. However, when Liz's reckless actions create a tsunami of unintended consequences, she recognizes that she's drowning in pent-up hurt and anger. As her carefully created façade begins to ebb away, she turns to her faith and sets off to chart a new course for her life.
