Eighteen months have passed since the rebellion escaped certain defeat at the hands of the Masters of the Conclave. Mathis has finally rejoined his rebel companions, as has Alia, a former Adept of the Conclave who still retains her psychic powers. The two are eager to continue the fight for the future of their country, Corinas. As the rebellion's influence grows, however, Headmaster Gersemi is willing to do whatever it takes to secure her authority, no matter the consequences. But when the Conclave's powerful child Adepts begin to disappear, both the Masters and the rebels must make difficult choices-and their decisions will determine who will control Corinas for good.
