Sequel to Hambly's Windrose Series. Exiled wizard Antryg Windrose and his partner, computer programmer Joanna Sheraton, discover that a trans-dimensional monster is hiding somewhere in the vicinity of Los Angeles. They track it down to the now-deserted luxury "ranch" of a deceased 1970s glam-rock star known as The Daemon (real name Harold Nedwick), only to discover that the creature has been there much longer than anyone suspected, hidden in the maze at the center of the property – and that it is about to spawn.
