The Raven Hills forest. Rumor has it that a werewolf roams among the woods day and night, searching for victims. Students at Raven Hills Junior High believe that a kid from their school became a victim of the werewolf after he vanished…without a trace.

Connor and Emily Graham, thirteen-year-old twins from Kansas, are having a hard time adjusting to life in Raven Hills, Pennsylvania—where they have gone to live after the tragic death of their parents. They're misfits in their new town, not able to relate to anyone but each other. They especially don't believe the crazy story about a werewolf.

In fact, Connor often seeks solace in the woods. And that's what he does after he has a horrible fight with his sister. He goes into the woods as he always has, needing some alone time to think.

Only he doesn’t come out.

Emily, determined to find her brother, searches the woods day after day. Haunting dreams seem to give her an ominous message, however—that her brother is no longer who he was. That he has been turned—into a werewolf.

However, nothing will stop Emily from looking for her brother. But she will soon learn that the Raven Hills forest holds deep and dark secrets. Secrets that will change their lives forever.
