Septimus Heap was born the seventh son of the seventh son, only to be immediately kidnapped and presumed dead by his parents. The same day, Silas Heap discovers a baby in the woods and, together with his wife, decide to raise the baby as their own.  Years pass and identities are discovered - and the chase is on between the killers of the queen and the family who raised her daughter.
