Necroscope: The Plague-Bearer (Necroscope #15)

Harry Keogh is moving on. Though the search for his missing wife and child continues, his heart now lies in Edinburgh with Bonnie Jean--a beautiful Scottish werewolf whose friendly pack and flourishing pub have given him a place he can almost call home.

But from the rocky heights of Sicily, the diabolical Francezci brothers plot the wolf-pack's destruction; and down in the terrible Pit beneath Le Manse Madonie, an ancient evil schemes.

The vampires conspire. They reach a decision. They choose a vector. Mafia thug Mike Milazzo is no good to anyone, anytime, anywhere…which makes him perfect. Disposable.

The brothers infect him with a deadly poison--an engineered plague that even a werewolf could never survive--and they offer him a terrible bargain: successfully contaminate the wolf-pack, and receive the antidote. Fail, and die!

Mike has everything to lose. So does Harry Keogh. But the Necroscope lost everything once before, and he isn't about to do it again...
