Penelope Yeager is like a lot of sixteen-year-olds--she wants more independence from her crazy mother; she wants to get her driver's license; and she wants to get out of high school, away from her town. More than anything, Lopi wants to find someone to really connect with, someone to love-- but short of that, she wants to have sex. She's already figured out how to graduate a year early, but the rest isn't so easy. For one thing, her mother, Vivian, isn't just crazy: she's young, vivacious, and beautiful. No one can resist Viv's charms, but Lopi knows it's all just an act. Viv is only pretending to be happy, trying to ignore Lopi and the horrible accident that changed everything between them. Lopi tries to pretend too, as she navigates the murky waters of sex and love and growing up, but she can't fool herself-- Lopi has a secret that sets her apart: the accident was her fault, she is evil . . .
