Jody Burns borrows her brother Peter's silvery bracelet because it looks good with her outfit. She doesn't remember it's the key to another world—until a green-haired girl steps out of nowhere in the mall and asks Jody's help rescuing her grandmother from a great evil.
Jody ignores Peter's warning about the land on the other side of the Watcher—until the haunted tree pulls her inside. Suddenly, she's trapped in a place where no one listens to her. And then her jacket starts sprouting leaves.
Return to the world where horses can be wizards, and trees talk, and an ancient evil is planning to destroy every last living thing.
