More groups join in: the London Knights, the Ghost Finders, the Spawn of Frankenstein, Shadows Fall, and the Soulhunters. Science and magic are running wild, there's blood running in the gutters, and the bodies are piling up.Is anyone going to get out of this alive?“A splendid riddle wrapped in a mystery inside an enigma, conveyed with trademark wisecracking humor, and carried out with maximum bloodshed and mayhem. In a word, irresistible.”-Kirkus Reviews, starred review
