To the students of the Spenser Academy; the Sons of Ipswich are the baddest boys on campus. But that's not all they share. The four friends also share a 300-year-old secret: they're warlocks; the teenage descendants of a 17th-century coven of witches. So when the long-banished fifth son 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.
