Olivia plans to achieve a perfect SAT score, attend a prestigious college, and become a doctor. The last thing she wants to do this summer is go on a cruise with her parents, younger brothers, and the weight that hangs over the family since her older brother's death. Sebastian isn't part of her plan: he's charming, exciting, and reckless. He's also fun. When past secrets begin to come to light, Olivia begins to question the past she thought she understood- and the future she's always planned.
