Walker, an earth shaman, has dedicated his life to the annihilation of the demon warriors who destroyed his desert tribe. As the lone survivor of the massacre, he atones by wreaking vengeance as a lethal mercenary. But his latest captive is a daring and new kind of challenge. She is the assassin Mehcredi, forced to work alongside Walker as penance for her crimes. Abandoned as a child, Mehcredi has no concept of human relationships, no reserve, no fears, and she boldly walks through Walker’s barriers as if they were mist.
