The Watcher’s Mask by Laurie J. Marks Book

    A two-souled person, Jamil the Watcher/Alasil the Executioner, has been the most loyal of the emperor’s minions. But time “blackouts” – periods when neither of her personalities can account for the actions of her body – cause her to fear she is succumbing to madness. Little does she realize she is beginning a journey of self-awareness that will lead her to discover the true nature of her race, and in so doing, to overturn the destiny of her world.
