Mages and demons. Their confrontation is as old as time. Many years ago, hellish creatures, sorcerers and people entered into an agreement that prohibits interfering in each other's affairs unless one faction poses a danger to the other. But today the days of demons are numbered, and Fabian will have to investigate the murder of one of them. The half-blood demoness North Tsirano turned to him for help when her brother, a pureblood demon, was killed, preventing his soul from returning to hell and being reborn. An undercover magician infiltrates the mercenaries' lair to prevent a bloody ritual and find out who is responsible for the brutal revenge. But with each discovery, the unwitting savior of the world is one step closer to death.
