This is yet another volume in Stross' "Laundry" series, and while I did like it and would certainly recommend it to other folks who have been following along with his Cthulhuey goodness, it didn't bowl me over the way most of his other Laundry books have. And I'm beginning to worry that our boy Bob is beginning to inch towards being a superhero, where each book has him sprouting a new mystical abilities like his player is spending XP on them. It's not as bad as I've seen it happen (the Anita Blake books being just about the worst example of protagonist power creep I can think of, and there are few authors indeed who can aspire to *that* lofty goal), but it's still a little distressing. And I certainly don't mind Bob getting better at what he does, but I kinda liked him as the somewhat nebbishy nerd, always just barely on the ragged edge of his own abilities and terrified the entire time. In this book (SPOILER ALERT TO END OF PARAGRAPH) he runs up against the undead wardens around a sleeping god (which often have a starring role in his nightmares) and, hey, lookit that, he can order them around because of his newfound ability to eat souls and recently-acquired knack for free-form magic. I fully expect him to be tossing lightning bolts around in the next book.
All in all, though, it's a good book, and despite my fears of what Bob "Mordenkanen" Howard might get up to in the next installment, I'm still looking forward to it.
