Hammer Down by A.J. Downey

Fish is still pretty new to his patch and has those moments where he still wants to respond to the odd bellowed ‘prospect!’ but he’s damn sure coming into his own. Great job, fully patched, decent apartment, and all his goals have been reached… all except one. A love of his own. He figured that would come in time but when he saw the scared and injured kitten dart into the roadway, he had no idea that time was now.
Kinzleigh Johnson had no idea what to make of the biker that brought an injured kitty cat into the twenty-four-hour animal hospital she worked at. She made out pretty quick that he was hot, and the fact that he was willing to throwdown his credit card and see to the poor fur baby without a second thought? Well, that told her he was at least good enough for a ride.
Save a horse, ride a biker?
Why she didn’t mind if she did. She had no idea it would end up more than she bargained for. A whole lot more.
