Vee Bell is certain of one unshakeable truth. Sophie was murdered. But how can she prove it? Everyone thinks Vee is narcoleptic, but her secret condition is far more terrifying. When Vee passes out she slides into other people's minds and can see the world through their eyes. She's seen her sister cheat on an exam and a frenemy do the unthinkable at prom, leaving Vee at the mercy of a cruel jock. But nothing prepares her for sliding into someone holding a bloody knife, standing over Sophie's body. Vee wishes she could share her secret, but who would believe her? She can't bring herself to tell her best friend, let alone the police. But when another cheerleader ends up dead, Vee knows she must find a way to unmask the killer before they strike again.
