Written in 1976, many of the correlations between the Book of Revelations and the state of the world are no longer immediately identifiable or as relevant which affects the overall feel and tone of the story, however, this slow-burn horror is still a decent read.

Religious horror has never been a preferred sub-genre of mine, with the exception of The Exorcist, so I wasn't sure how much I'd enjoy this book.

In the end, I found the plot intriguing, and I enjoyed the overall story, but I did feel that the atmosphere suffered on multiple occasions due to pacing issues. I also kept wanting there to be more to the themes that were touched on but never really developed and I think there needed to be more ambiguity in regards to what was occurring in order to really draw the reader in.

While it doesn't invite a reread, I would still recommend this book to fans of the genre.
