In his undead quest for justice, Felix Gomez-detective vampire extraordinaire-has traveled from dusty desert battlefields, to gritty urban barrios, to the deepest corners of outer space. Now he's about to embark on his wildest adventure yet: back to an alternative past of steam-powered technology, telepathic magic, and intrigue more deadly and unforgiving than any he has ever encountered. There, he's a renowned pistolero hired to find the missing daughter of notorious Chinese gangster Wu-Fei. Accompanied by philosopher-gunfighter Malachi Hunter and mercenary femme fatale Hermosa Singer, Felix follows clues through the reimagined Southwest of Aztlan to the Gulf of California. The fate of Wu Fei's daughter is known only to the sex slaves imprisoned on Isla Tiburón-Shark Island-the fortress home of a mad scientist whose ambitions are as twisted as her evil genius. Getting on the island proves tough. Getting off the island proves impossible. But to learn what happened to Wu Fei's daughter, Felix must brave a gauntlet of murderous henchmen, infernal machines, and ferocious prehistoric monsters. And don't forget the sharks.
