Larkin and Reagan have always been at odds, competing for everything Larkin lost two years of her life to post-concussion syndrome. As she stands at the beginning of her new life, she wonders if she's even the same person she once was. Abandoned by friends when she was injured, she takes her first step toward her future: alone. Was it a mistake for her to go back to school for her senior year? Will they laugh at her panic attacks? Will they notice she isn't eating? Will she even make it through the first day? Beautiful, tough, popular . . . cunning, Reagan puts on a good show. No one notices the pain she holds deep within and she prefers it that way. Her life is nothing, just like her mother says, but it looks perfect. When Larkin went down, Reagan stepped into her shoes. Two years later, Reagan has her senior year all planned out. One perfect year leading to the day she can finally escape her mother's grasp and leave for college. Her nightmare over. Or is it? When Reagan and Larkin find themselves face to face on the first day of their senior year, lightning strikes.
