Four years have passed since the clash between people and the Deep Kings. Valengrad, a city on the border with Morok, a vast desert where nightmares reign, remains uneasy. Now the night sky is illuminated by lights that bring death to all living things, and a power-hungry religious cult is gaining strength in the streets. These are followers of the Light Lady, a ghost woven from light who appears to people every now and then. Rihalt Galharrow's life has not changed for the better, but working for Crowfoot, a powerful sorcerer, has become even more difficult, because lately his orders have been either completely incomprehensible or downright insane. When an artifact of terrifying power is stolen from the Crow's Foot vault, Galharrow must figure out which of Valengrad's many enemies is responsible for this crime before it's too late. To do this, he and his squad will have to go to a place much darker and more dangerous than all those they have visited - to the very heart of Morok.
