From back of book: All of the world is kept in a delicate balance under the supervision of the Wizard Lord. It is his duty to govern lightly and protect his domain...but if he should stray from the way of the just then it is up to the Chosen to intercede. The Chosen are the Leader, the Seer, the Swordsman, the Beauty, the Thief, the Scholar, the Archer, and the Speaker, magically infused mortal individuals who for the term of their service have only one function--to remove an errant Wizard Lord.

But the new Wizard Lord has changed the playing field by neutralizing all magic in his domain (both his own and that of the Chosen) and has successfully killed and/or blocked his adversaries and their challenges to his omnipotence. Sward (now on the run) must work alone to restore order to the land and unravel the mystery of the Ninth Talisman--which might be the salvation or downfall of all that is good.
