She sees through the eyes of a killer ...
Sylvia "Vee" Bell hates that, like her deceased mother, she has narcolepsy. But this embarrassing condition is nowhere near as bad as what happens during these episodes: when Vee passes out she actually slides into somebody else's conciousness and experiences the world through that person's eyes. This is how Vee finds herself in the head of a killer, standing over a classmate's slashed and murdered body.
When another cheerleader turns up dead, Vee realizes that someone is killing off her sister's friends. Suddenly everyone is a suspect, and Vee finds herself enmeshed in a terrifying web of secrets, lies and danger. She must face up to the fact that she can trust no one-not even the family and friends she thought she knew.
