Brothers of the Fang

Detective Mike Bane is a shape shifter with two beasts:  a 300-lb black jaguar with a taste for turtle meat, and a psychotic Olmec shaman named Tehuantl with a taste for blood. 

When Mike accepts a security job at Mythica, America’s only supernatural theme park, he discovers an unexpected kinship with the park’s werewolf pack.  But when his curiosity gets the best of him, he's ensnared in a centuries-old feud between Mythica’s vampires and the fae of the neighboring High Tor clan.  Only Tehuantl's magic can save Mike’s brothers of the fang; in return, Tehuantl wants permanent possession of Mike’s body, mind, and soul.
