The Covenant

To the students of the Spencer's academy, the daughter and the sons of Ipswich are the baddest girl and boys on campus. But that's not all they share. The five friends also share a 300-year-old secret: they're warlocks and a witch, the teenage descendants of a 17-century coven of witches. So when the long-banished sixth member suddenly appears and threatens to kill their loved ones, they realize they must face their enemy in order to prevent him from stealing their powers and shattering THE COVENANT forever.
