Cassie Palmer is in trouble. She recently became the Pythia, the most powerful psychic in the world. Unfortunately, she is bound by a spell to a vampire named Mircea. If she completes the spell, she will end up being under his control for the rest of her life. Her only hope is a book named the Codex: a spell book written by Merlin himself that contains the only spell that can release her from Mircea's control. There are only two problems with retrieving the book: The Dark Circle (The bad people) want the book and the book had disappeared in the seventeenth century. With the help of her friend, Pritkin, can Cassie break the spell and eventually save the world?
