To Kill a Ghost

Who knew vampires were ghost repellent?
Arawn Sage has a ghost problem. The warden of the facility where he once was held captive has come back to haunt him, and Arawn has no idea what to do about it. There is no way to keep a ghost out, and the warden is preventing Arawn from sleeping while trying to persuade him to do things he doesn't want to do. It isn't until he accidentally touches a vampire and the ghost momentarily disappears, he feels a sliver of hope. Maybe there is a way out of this torture.
Zidane Dodd has been staked in the basement of a castle for close to a year. He can't move. He can't breathe. He can't talk. And he's bored out of his mind. But one night, Arawn comes down there to hold his hand. He can't feel it, but since he has nothing better to do, he doesn't mind playing safety blanket for a scared little ghost whisperer.
There has to be a way to get rid of a ghost. Arawn has no idea how, but he can't walk around touching vampires whenever he needs a break, can he?
