In a world where a werecat virus has changed society, Roan McKichan, a born infected and ex-cop, works as a private detective trying to solve crimes involving other infecteds. The murder of a former cop draws Roan into an odd case where an unidentifiable species of cat appears to be showing an unusual level of intelligence. He juggles that with trying to find a missing teenage boy, who, unbeknownst to his parents, was "cat" obsessed. And when someone is brutally murdering infecteds, Eli Winters, leader of the Church of the Divine Transformation, hires Roan to find the killer before he closes in on Eli. Working the crimes will lead Roan through a maze of hate, personal grudges, and mortal danger. With help from his tiger-strain infected partner, Paris Lehane, he does his best to survive in a world that hates and fears their kind... and occasionally worships them.
