Big, Bad Gruff - Eve Langlais

This detective is bringing the handcuffs—and the bite.
When Brandy finds herself accidentally mated to a werewolf, she's totally cool with it. If only Detective Gruff felt the same way. The man is so darned scared he runs away to a remote cabin in the woods.
Lucky for him, Brandy isn't about to give up.
Billy never wanted to get hitched. He'd seen firsthand with his parents how ugly it could get. He never counted on meeting Brandy, a feisty nurse with a bubbly outlook on life who looks past his grumpy facade.
It isn't just danger that brings them together. She is temptation itself.
When she's taken from him, he realizes he'll do anything, even unleash the big bad wolf, to save her.
