Will Kingdom: The Cold Calling (UK 1998)
From the Publisher:
When Bobby Maiden is revived after dying in an accident, his memories are of a harsh place he doesn't wish to revisit. But his experience means that he may be able to reach a serial murderer who returns to stone circles, burial mounds, and churches in the belief that he is defending Britain's heritage.
