Bridget Sinclair, new Special Agent with the Cougar Special Forces Division that takes down rogue cougars, has a mission-permanently stop two shifters from distributing a new drug in Cheyenne, Wyoming. While investigating, she rescues a man they've tranquilized and learns Travis MacKay is a cougar shifter with the same law enforcement agency. Winter advisories are in effect for the Christmas holidays, but that doesn't cool off the sizzling heat spiraling out of control between the two agents as they covertly team up to take down the drug-runners.
