Everything Stross gets an automatic 4 stars for me. The creeping dread of the Laundry Files is a much enjoyed setting for me. That being said, this one only gets the base 4 stars. I just get the feeling that when he moves the story to an American setting the books are just a little weaker (the same feeling I got with the Apocalypse Codex). Still, this was a rollicking read and moved the overall story along nicely.

Upping to 4.5 stars. Seems when I read this before I may have missed a bit of nuance or something because I definitely underrated it slightly.
