Stephen Neilson, shape-shifter and Tracker, polices the hidden supernatural world. Sometimes, his job makes him think he’s little more than a paid killer. This belief is tested to the limit when Miranda Winter arrives at his door, asking him to look for her missing sister, Amy. She definitely is a killer, one who specialises in non-human targets.
That search leads to York, following the only piece of information he has: that Amy Winter was working for vampire and old friend Evan Philips. He reveals Winter was helping him catch a shadowy figure who had managed both to band together the local werewolves and to do the unthinkable: corrupt a Tracker.
Neilson must confront the side of himself that he despises as he continues to search and faces a much larger threat, one that could potentially reveal the supernatural world to the human population.
