Tasker House - Unquiet Magic, #2

A year ago Jack Belamit and Carlos Colosio went in search of Jack's father, the incubus Belamit. With the aid of Belamit's beautiful and terrifying business rival, the sorceress Anaksut, their mission was a success, and now a detente of sorts prevails between Anaksut and the Belamit family. Jack's brother Rafe has gone into the real estate business with the witch, and the future looks bright. When Rafe and Anaksut buy a romantic resort hotel on the shores of Canada's Georgian Bay, however, they discover that the hotel is haunted by a naked ghost who roams the halls apparently searching for something or someone.
Rafe hires Jack and Carlos to deal with the ghost, accompanied by one of Anaksut's employees, a cheerful young man called Bob who previously spent a hundred years and a day in the form of a pig on Anaksut's Mediterranean island. While he and Carlos are investigating the mysterious tower that stands at the center of the hotel, Jack is snatched away through time by the ghost. Dragged into the past to serve as a slave to the unbalanced Adrian Tasker and his Brotherhood, Jack must overcome Tasker and find a way back to his own time before Tasker seals off the pathway to the future forever.
