Shanna is positive high school will be no better. But when she meets Jonah Leighton, everything changes. Though most other kids make fun of and even fear Jonah, Shanna finds him to be kind and thoughtful, and he amazes her with the things he knows. Even more amazing, he wants to teach her what he’s learned, and he wants to be her friend.

Only Jonah seems to know what’s going on, and he persuades Shanna to work with him to help Kaylie. But can the two of them rid Kaylie of the entity that wants to take over? And can Shanna trust herself enough to do what Jonah needs her to?
