Shadow Kiss by Alyssa Rose Ivy

Gabriella can talk to ghosts, but that isn’t her biggest problem. That would be Rexton, the sexy as sin incubus she can’t seem to stay away from. He’s offering her a chance to learn about her gift as well as a job, but she knows there’s a lot more on the table.
Rexton hasn’t been able to get Gabriella out of his head since he met her months before. He’s an incubus, he’s supposed to make people obsessed not the other way around, but it seems the tables are turned.
Both Gabriella and Rexton know the dangers of mixing business with pleasure, but some desires can’t be ignored.
