This is an enjoyable book to read, on par with work by Tom Clancy, Ralph Peters, and Harold Coyl. Revelation ignores much of the global powerplays of WWIII (set in 1985) in favor of an "in the trenches" viewpoint with a handful of characters, not all of whom are soldiers. As a fan of war fiction and horror fiction, this is a good blend of both in genres that don't always work well together. The characters are well written and develop as the novel progresses.
There is a heavy supernatural influence in the plot, with several main characters of supernatural orgin. It reminds me of games such as Wierd War and some Call of Cthulhu supplements. The fact that the story goes back and forth in time is a little jarring, and had me flipping back through the pages to remind myself of the timeline of major events, but anyone with any experience with war fiction won't be put off.
