This novel is the second Christian thriller by Frank Peretti, and sort of a sequel to This Present Darkness. It portrays problems in small-town America which are mirrored in the spiritual realm with angels and demons battling for lives and souls. It's exciting enough that it would probably be enjoyed by anyone who likes action-packed thrilling novels although it probably makes more sense to Christians.

As encouragement for Christians to stand up for what they believe, and to keep praying, it's probably quite successful. However the book IS fiction, and it's important to remember that Peretti's spiritual battles are only his interpretation of a possible scenario. Some critics complain that his theology is off-beam, but I don't think that's really fair: he's not teaching theology, he's writing a novel.

It's a good read which was almost as gripping the third time I read it as it was the first time, about 12 years previously.
