The battle for control over the Order of Alhazred mounts as Nicodemus's only heir, Cassandra, is challenged over her right to be grandmaster. But then Timothy discovers that the evil ancient sorceror, Alhazred is still alive - and has gathered nearly enough dark power to take back control of his order. Timothy and Cassandra must become reluctant allies in their battle to stop Alhazred regaining power. But are they strong enough to fight his magic?
