This is the second time I'll be reading the Laundry Files to get to the new stuff I haven't. It has so many great aspects that bring those big smiles on my face, namely: Cthulhu hacking spy comedy. The first time I read it, I didn't realize these novels were all based individually on the style of different spy fiction authors, which will end soon and be based solely upon Charles Stross's style. It is an easy and fun read and tickles all my genre bones, so it therefore qualifies in some of very top lists for must-reads. That isn't to say the novel doesn't have it's dry spots, either in the admittedly authentic sounding military jargon or the specialized mathematical humor that may or may not be lost upon many readers; even so, the voice never falters and the humorous parts are definitely humorous. I will admit that I am a fanboy of his works and will always be skewed in his favor. Guilty pleasures, and all that.
