Unholy Passion by Nicola C. Priest

Sometimes, it’s our inexperience that’s sexiest.

When Charlie Miller decides she’s had enough of University, going back home is the only plan she has. An independent woman, men have never been important to Charlie, but when she first sees Isaac, the too good-looking manager of the venue where her brother will perform his first gig, she can’t get him out of her head.
Charlie intrigues Isaac Hamilton from the first moment he meets her. Despite their age difference, he makes it his mission to get to know her better, but there’s a dark side to him that he only shows to a few people, and he wants to show it to Charlie.
The passion they share is explosive, but will Charlie be on board with Isaac’s darkest desires, or will his urges prove too much for her to handle?
