Liam by Kathi S. Barton

Emma Hudson wanted to get this over with. Her father had left her in a jam, and the sooner she dropped off his duplicate trucker log books to the Harrisons, the sooner she could get back to work and try to clear her name. Trucking was all she knew, and she was tired of it.
Liam Harrison watched the pretty little thing climb into her truck to get the books, but when she slipped and fell back into his arms with a life-threatening cut on her arm, he knew two things: she was his mate, and she would die if he didn’t convert her right now.
And when a string of rest stop murders brings an old vampire friend back into the family’s fold, he informs them Emma was next. It was time to park the truck.

They all knew that Emma’s father would come sniffing around to try to swindle her out of more money, it was just a matter of time. But how far would he go to get what he wanted?
