I am the in the main audience for this book. I enjoy spiritual thrillers. I love the Exorcist, Dan Brown's books, you name it. If it's got elements of the Devil, or questioning religion, or bigger spiritual themes I'm your huckleberry. So what did I think?
The Goods - As a conclusion to the trilogy, this was fairly satisfactory. I really can't think of any other way this would have ended given how Harbron set up God and the Devil. Banbury was given a Choice to judge of how things were to be moving forward and I see why he made the choice he did. It was an interesting read and honestly, all that kept me moving forward was to see how Banbury and Satan would interact.
The Bads - As the trilogy proceeded the typos and grammatical errors got worse. Harbron used words that I'm not entirely sure he knew the meanings of. He really needed an editor for all three books. Ordinarily, I don't make a big deal out of this, but it happened enough to take me out of the story several times. I'm also not a big fan of how he used God in the story. That's not to say he was "unfair" to God. It's his universe. I just think it would have been more interesting if God had been more of a character in this series than they were. The God in this universe was about a half inch deep. There were also some theological errors in the story, ones that showed either Banbury or the author weren't the studied person in this area that they needed to be. Again, Christianity has its issues, certainly. But if someone like Banbury is going to write a take down of a major world religion and it's going to be a best seller, he needs to be shown to be more knowledgeable than your average Reddit poster.
The Verdict - In spite of my lengthy list of "Bads", I did enjoy reading this series. I enjoyed the first book the most and the last book the least. If you're looking for a fun read that's occasionally interesting, and what I've posted above doesn't turn you off give it a chance.
