In this contemporary murder mystery/romance novel, werewolves exist and have always lived in small numbers around the world. A few years before this story starts werewolves outed themselves to the US government in order to better liaison with law enforcement to address werewolf-human crimes, but the general public still does not know werewolves exist. Cooper Dayton survived a werewolf attack, and is subsequently transferred from his former job at the FBI into the BSI, the Bureau of Special Investigation. When two bodies turn up in the woods in rural Maine, Agent Dayton is chosen for a trial program, and he is paired up with an agent from The Trust, the werewolf government. Dayton is attracted to his new partner, Agent Park, immediately- but when it turns out Park's family is active in the area of the murder, Dayton realizes he can't rule out the possibility that his co-worker might be actively covering for the criminal. This book starts an enjoyable paranormal romance series complete with plenty of spice but also very solid procedural mysteries. I was glad to be able to guess some parts of, but not all of, the mystery as it unfolded and I also thought the romance novel beats hit well!
