Fortune of the Witch by Deanna Chase

Medium Harlow Thane has given up her life as a celebrity paranormal investigator. After her life was turned upside down by a devious and illusive ghost, all she wants is to settle down in Keating Hollow, running the new pub in town. Unfortunately for her, no matter how much she wants to give up ghost hunting, the ghosts won’t quit her. Neither will her ex Cash Moses. With a ghost she just can’t seem to banish and her ex hell-bent on righting the past, it looks like Harlow’s plan for a quiet life isn’t in the cards.

Cash Moses wants two things: revenge against the ghost who stole everything from him and Harlow Thane. In order to track down and eradicate the ghost, he needs Harlow’s help, except she’s not interested. Not in the ghost and not in him… or so she says. Somehow, he needs to find a way to get past her defenses so they can move on from their past and finally get their happily-ever-after.
