Twelve-year-old Moll Pecksniff wakes one night in the middle of the forest, lured there by a recurring nightmare - the one with the drums and the rattles and the masks. The Dreamsnatcher is waiting. He has already taken her dreams and now he wants her life.

Because Moll is more important than she knows... The Oracle Bones foretold that she and Gryff, a wildcat that has always been by her side, are the only ones who can fight back against the Dreamsnatcher's dark magic. Suddenly everything is at stake, and Moll is drawn into a world full of secrets, magic and adventure.
