Cash Fraser is planning revenge and to get it he needs the perfect woman. So he hires her. Abigail Butler has lost nearly everything in her life and she's about to lose the home she loves.

Cash meets Abby, who is posing as a paid escort, and the minute he does he knows he's willing to pay for more than Abby being his pretend girlfriend. A lot more. Abby needs the money or the last thing that links her to her dead family and husband will be gone. The deal is struck but both Cash and Abby get more than they bargained for.

Cash realises very quickly that Abby isn't what she seems and while he changes strategies, Abby discovers that Cash's legacy, Penmort Castle, is like all the tales say – very, very haunted. Making matters worse, the ghost in residence wants her dead.

Abby's found herself in the battle of her life so she enlists Mrs. Truman, her nosy neighbour; Jenny, her no-nonsense friend; Cassandra McNabb, white witch and clairvoyant with a penchant for wearing scarves (and lots of them); and Angus McPherson, dyed-in-the-wool Scot (which means he hunts ghosts in a kilt) to fight the vicious ghost who has vowed that she will rest at nothing to kill the true, abiding love of the master of Penmort.
