Academy Award-winner director Guillermo del Toro teams up again with acclaimed thriller writer Chuck Hogan in this blood-chilling novel about an ancient secret that was never meant to be unleashed. This Deluxe Edition will have full color endpapers and black and white illustrations, with bespoke designed edges. Film Adaptation Coming Soon From Netflix! A group of mercenaries on an unsanctioned mission survives a plane crash in whiteout conditions in the Tian Shan mountains. The men are accustomed to danger. Now they're growing accustomed to fear. Team leader Liev and his band of survivors are stranded in the bitter winds with little hope of rescue--or outlasting the wolves that have scented blood. In the distance is the apparent sanctuary of an abandoned stone fortress. That an ancient bulwark even exists on this forsaken summit is beyond comprehension.

So is what lies on the other side of its walls.
