Starlight by Terry Bolryder

Theo Lancaster isn’t just the world’s best surgeon. He’s also a night-stalking monster, a creature of darkness. At least, some of the time. Thanks to his best nurse, Theo has had an ace in the hole for several years now. That is, until she threatens to leave. Only then does he realize she’s much more than just another coworker, and the only human his heart could want.

Ada has had the hots for Dr. Lancaster for a very long time. And who wouldn’t, with his perfect body, striking features and incredible talents? Maybe some people, given his arrogant, aloof personality that pushes everyone away. Which is why she’s leaving before heartache gets the best of her. But to her surprise, Theo seems to have other plans in store. What starts as a desperate bid to keep his best nurse at his side quickly becomes much more for Theo and Ada as repressed feelings held back for years come rushing out between them, igniting sparks inside the bedroom and out. But foul forces hidden away from humanity are about to break free, offering answers to the Lancasters’ questions about their existence, and endangering everything Theo has ever held dear.
