A massive fantasy omnibus containing all three novels in the Obsidian and Blood series: SERVANT OF THE UNDERWORLD The end of the world is kept at bay only by the magic of human sacrifice. A priestess disappears from an empty room drenched in blood. Acatl, high priest, must find her, or break the boundaries between the worlds of the living and the dead. HARBINGER OF THE STORM The Mexica Empire lies vulnerable to the flesh-eating star-demons. When a councilman is found dead, only Acatl, High Priest of the Dead, can solve the mystery. MASTER OF THE HOUSE OF DARTS The armies of the new Emperor retreat with a mere forty prisoners of war – not near enough sacrifices to ensure the favor of the gods. When one dies of a magical illness, Acatl is summoned to investigate.
