Dark Stranger by Jess Holden

She doesn’t believe in vampires…
Journalist Dani Sokolov writes for science mags and has no belief in the paranormal. On her way to a getaway in the Virginian countryside, her car breaks down, and Dani becomes aware that some dark force seems to be shadowing her. A devastatingly handsome stranger appears out of nowhere and offers her a ride.
The mystery man is none other than Savitr, owner of the Montefiori Inn, and he knows the creature that hunts Dani. Despite Dani’s words to the contrary, he is well aware that she is as attracted to him as he is to her. But he made a promise to Dani’s father, that he would keep Dani safe, and that is what he intends to do, whether she likes it or not.
