Wanted: Demon assistant for incubus genius. Personal services required…
Nobody ever expected to find a secret cave protected by a giant puzzle door in the mountains near our village. Even more surprising was the knowledge that it’s been there for thousands of years and was created by a dragon. I’m not the only one who’s dying to find out what’s inside.
It’s no hardship to assist the puzzle expert who’s coming to solve the door. That thing is an incredible feat of engineering, and the man who’ll solve it is bound to be intelligent and interesting. But from the moment I meet Camden Torrence, I’m forced to reassess… everything.
He’s intelligent and interesting, sure. But he’s also scattered. Clumsy. And I want to bury my face in his mop of curls and stay there forever.
A relationship wasn’t on my agenda, no matter what my matchmaking family wants. But as the weeks go by and we get closer to discovering what the secret treasure is, Cam becomes an integral, undeniable part of my life. How can I not fall for a man who, despite past hurts, is the living embodiment of sunshine in our snow-laden village?
I never thought the love of my life would turn out to be an adorable, absent-minded incubus, but now I can’t imagine existing without him. The challenge? Convincing him to stay even after the puzzle is solved.
