The Wolf at the Door: The Big Bad Wolf Series

A former FBI agent is partnered with the enemy in this suspenseful male/male shifter romance from debut author Charlie Adhara.
Hunting for big bad wolves was never part of Agent Cooper Dayton's plan, but a werewolf attack lands him in the carefully guarded Bureau of Special Investigations. A new case comes with a new partner: ruggedly sexy werewolf Oliver Park.
Park is an agent of The Trust, a werewolf oversight organization working to ease escalating tensions with the BSI. But as far as Cooper's concerned, it's failing. As they investigate a series of mysterious deaths unlike anything they've seen, every bone in Cooper's body is suspicious of his new partner - even when Park proves himself as competent as he is utterly captivating.
When more people vanish, pressure to solve the case skyrockets. And though he'd resolved to keep things professional, Cooper's friction with Park soon erupts…into a physical need that can't be contained or controlled. But with a body count that's rising by the day, werewolves and humans are in equal danger. If Cooper and Park don't catch the killer soon, one - or both - of them could be the next to go.
Contains mature themes.
