With the help of their new friend Misty, Topher James and his friends must fight a force of darkness. But is Misty really on their side?

When Topher James and Blake Walker receive an email from a girl named Misty saying that "something dark" has taken her sister, they know they will have to once again fight the force of darkness they've fought before. The nightmares Topher's girlfriend Callie Monroe is having confirm that, and also warn against becoming involved with Misty. But something about Misty sucks Topher in, and he's unable to resist her.

Alienated from Callie and his friends because of Misty, Topher still intends to fight the darkness. But it---and Misty---have other plans, and only Faith Carlisle can make Topher see the light before it's too late.
