Revenge of the Witch (Joseph Delaney)

Summary: For years, Old Gregory has been the Spook for the country, ridding the local villages of evil.  Now his time is coming to an end.  But who will take over for him?  Twenty-nine apprentices have tried--some floundered, some fled, some failed to stay alive.

Only Thomas Ward is left.  He's the last hope, the last apprentice. (from amazon.com)
