If I Stay meets One of Us is Lying in this gripping contemporary thriller.

When band-geek Ivy and her friends get together, things start with a rousing board game and end with arguments about Star Wars.

Her older sister Autumn is a different story. Enigmatic, aloof, and tough as nails, Autumn hasn't had real friends--or trusted anyone--in years. Even Ivy.

But Autumn might not be tough enough. After a drug deal gone wrong, Autumn is beaten, bound, and held hostage. Now, trapped between life and death, she leaves her body, seeking help. No one can sense her presence--except her sister.

When Autumn doesn't come home, Ivy just knows she's in trouble. Unable to escape the chilling feeling that something isn't right, Ivy follows a string of clues that bring her closer to rescuing her sister... and closer to danger.

Autumn needs Ivy to find her before time runs out. But soon, both sisters realize that finding her also means untangling the secrets that lead to the truth--about where they're hiding Autumn, and what Autumn has been hiding.
