The Vulfan’s Dark Desires by Georgette St. Clair

Alien wolf shifter Treffon Thorolf has given up on finding his True Mate – after all, he’s only been searching for a century. Before the Darkness can consume him, he’ll go out his own way – in glorious battle against the cyborgs. That is the plan right up to the moment when curvy, clumsy Violet Dufresne literally stumbles into his life and spills a drink down his pants.
The awkward little Earth woman stirs strange feelings in him – but unfortunately, she’s got a price on her head, and no idea why. So what if she’s not his True Mate? He’ll fight off the entire Galactic Federation to protect Violet from the dark forces that pursue her. He’d give his life for her – too bad he can’t offer his heart.
