The Wolf at the Door

Cooper Dayton is an ex-FBI agent who never planned to hunt werewolves. After a werewolf attack, he ends up in the Bureau of Special Investigations, a closely guarded unit that deals with them.

His first case there comes with a new partner, Oliver Park, a werewolf who works for The Trust. That organization exists to ease rising tensions between werewolves and the BSI, though Cooper considers it a failure. Together they look into a run of strange deaths unlike any either has handled.

Cooper distrusts Park from the start, and Park's skill on the case does nothing to settle that. More people go missing, and the pressure to close the case grows. Cooper intends to keep the partnership strictly professional, but the friction between the two men turns into a physical attraction neither can easily control.

This is a paranormal thriller with a romance between two men running through the investigation, a slow-burning suspicion alongside a rising body count. Both humans and werewolves are at risk, and if the killer is not caught, Cooper or Park could be the next victim. It is the first book in the Big Bad Wolf series.
