I rather enjoyed this book, although as the previous poster said, it’s not great literature (although almost anything is better written than the “Left Behind” series). There are lots of interesting characters, some fictional some based on historical figures, but the dialgue is stilted in some places and the expository sections where characters spend several paragraphs explaining salvation history and theology are so contrived as to make me audibly sigh. The theology as it addresses the Book of Revelation is definitely not of the deeply flawed “Left Behind”/Pre-Trib variety and is, so far, indeed closer to the Catholic view in that the Book of Revelation is primarily referring to events that occured in the first century.
I say “so far” since this book is the first in a series (two more expected, I believe). Because of that, I would hesitate to recommend it to other Catholics until I see how the other books come out. Plus the book concludes with a plug for CRI, the co-author’s organization that promotes some erroneous ideas of Catholic teaching.
