Samantha is a stranger in her own life. Until the night she disappeared with her best friend Cassie, everyone said Sam had it all: popularity, wealth and a dream boyfriend. Sam has resurfaced, but he doesn't remember who he was or what happened to him that night. As he tries to rebuild his old life, he realizes that he no longer wants to be a part of it. Old Sam took "bad girl" to a whole new level, and it's clear that she and Cassie were more like the best of enemies. Sam is pretty sure that losing her memories is like winning the lottery. She has a second chance to be a better daughter, sister, and friend, and she's falling in love with Carson Ortiz, a boy who has always cared for her, even if old Sam treated him like trash. But Cassie is still missing, and the facts about what happened to her that night aren't just buried deep in Sam's memory; someone else knows, someone who wants to make sure Sam stays quiet. All Sam wants is the truth, and if he can unlock his cloudy memories of that fateful night, he can finally move on. But what if not remembering is the only thing keeping Sam alive?
