The Summer Palace: Volume Three of the Annals of the Chosen / Lawrence Watt-Evans,

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 now changed the playing field by neutralizing all magic in his domain, both his own and that of the Chosen, and he has successfully killed his adversaries or blocked their challenges to his omnipotence. Now on the run, Sword must work alone to restore order to their fair land and unravel the mystery of the Ninth Talisman―which might be the salvation or downfall of all that is good in their well-ordered land.
The Summer Palace is the conclusion of TheAnnals of the Chosen, an epic fantasy trilogy of duty, honor, and abuse of power by the award-winning author Lawrence Watt-Evans.
