Marcus Barber is a two thousand-year-old immortal who works as a bounty hunter for powerful entities of the ancient world. When not pounding the pavement as a private investigator for mortal clients, Marcus chases down missing mythological creatures for the Ancients. In the heat of San Antonio, Marcus must search for Nemesis’s missing griffin while trying to rescue a melting ice pixie from an eccentric collector. His adventures put him on the trail of a cult of Ereshkigal who have kidnapped a Daughter of Freyja. While roaming the sprawling metroplex, Marcus gets tasked with obtaining Chaac’s lightning axe from the grasp of Tawhaki. Given tight deadlines by all of the Ancients who treat Marcus as a pawn in their games, he enlists a friend’s help but must hide the strange events and creatures from his mortal friend’s awareness. On top of the Ancients’ requirements, Marcus gets a call from an assistant district attorney who wants him to track down a missing mistress … who Marcus has his own, very distant past with. By leveraging his stubbornness and honed skills, Marcus must accomplish everything in twenty-four hours to keep his immortal soul away from the Ancients.
