Willa Parker, 646th and least popular resident of What Cheer, Iowa, is headed east to start a new life. Did she choose this new life? No, because that would be too easy--and nothing in Willa's life is easy. It's her famous genius mother's idea to send her to ultra-expensive, ultra-exclusive Pembroke Prep, and it's only the strength of her name that got Willa accepted in the first place. But Willa has no intentions of fitting in at Pembroke. She's not staying long, she decides. Not at this school--and not on this planet. But when she meets peculiar, glittering Remy Taft, the richest, most mysterious girl on campus, she starts to see a foothold in this foreign world--a place where she could maybe, possibly, sort of fit. When Willa looks at Remy, she sees a girl who has everything. But for Remy, having everything comes at a price. And as she spirals out of control, Willa can feel her spinning right out of her grasp. In Willa's secret heart, all she's ever wanted is to belong. But if Remy, the girl who gave her this world, is slip-sliding away, is Willa meant to follow her down?
