This book goes through the events of what seems to be six months or so in the life of a teenaged girl who has just moved across town. Sadie is normal enough. She's got a good set of friends, a life you might say. But even though its just an hour away the move is more influential than you might think at first. A new school means new friends. And new friends means a chance to be a whole new you. Or at least that's Sadie's philosophy. Her mistake, not thinking through the implications of having a new face ... That's a lie.

When Sadie moves to Plainfield Community High School, she wants to change herself and be interesting . . . even if that means lying. After meeting a girl that has a deathly allergy to peanuts, Sadie knows exactly how she will become different. At her new school, she tells everybody she has an allergy to peanuts and if she eats anything containing peanuts, she could potentially die. This white lie keeps growing and growing and she starts to wonder how much longer she can keep doing it. Will it affect her relationship with not only her new friends but also her new boyfriend?
