Apparently, this sat unread on my shelf for the past 15 years, because I didn't recognize anything about it (I know it's 15 years old, but when I've reread any of the other books from my CBA shelf, they've been familiar to me, even if I didn't remember the details). I wonder what stopped me.
Anyway, reading it now, I wasn't as impressed as I might have been then. OTOH, even then, I was tired of the CBA trope that all scifi has to tie in to the End Times. But it was well written, with an engaging story. If you haven't tired of the trope, and you enjoy an x-filish conspiracy, you'll probably enjoy it more tham I did.
