Query: Dull.

I've never been a huge fan of O'Brien and his dreary end-of-the-world books, but I thought I'd give this one a shot.Not for the first time with O'Brien's novels, I found myself putting it down with a yawn, and never picking it up again. This has also been the experience of two friends of mine, who (unlike myself) are HUGE fans of O'Brien's previous apocalyptic novels, and who have absolutely devoured his other works. This, however, they couldn't even bring themselves to finish... "No, really," they tell me, "his OTHER books are great." I'm sorry, but there are too many authentically and consistently good authors in the world for me to waste any more time on this one. Life's too short... especially if you believe, like O'Brien, that we are in the End Times right now.
