A gritty sci-fi story about genetic tyranny and family secrets, from the author of acclaimed true crime thriller Operation Devil Horns.

Eric Keller is a rising-star special agent with the federal Department of Human Genome, but his life isn't as perfect as it seems. The genetic edits that Keller's ultrarich mother performed on him as a child (but never told him about) are wearing off, and his body is undergoing strange changes.

Compounding his troubles, Keller's new girlfriend thinks he's a rat, and his partner at DHG is a dirty backstabbing cop. In discovering the true nature of the system that he serves, Keller must confront shocking facts about the evolution of modern humans, as well as face his own troubled family's origins.
