Seventeen-year-old Grace Flynn can't remember anything from the night her best friend Jennifer died in a terrible car accident. Not even if she was the one behind the wheel. On the day before she is supposed to go to jail for a crime she may or may not have committed, Grace decides to retrace her steps from that fateful night and jog her own memory. Tagging along for the ride is Jennifer herself… or rather Grace's memory of her… back from the grave to help Grace discover the truth. Even as a mere reflection of her former self, Jennifer is a force to be reckoned with; a gorgeous, wild creature with a taste for danger. Jennifer pushes Grace to the edge and forces her to remember what she has been trying to forget. Together the girls navigate ex-boyfriends, parents, foes and friends who all have their own secrets from that dark night. In the end, only Jennifer can help Grace face not only the events of the past, but the hope for her future.
