I remember seeing this in a book shop with a shiny silver highlight on the cover, and recognisng the name of the author of "The Wasp Factory", which I had read and really enjoyed. But what was he doing in the SF section, and what was the "M" all about? I guessed correctly that here was an author living a double life in so-called literature AND my home base of genre fiction, especially SF. And I found his SF was far superior to his realistic fiction or whatever you call that rubbish :-).

On early readings I didn't quite absorb the brilliant creation of Banks' future utopia the Culture, partly because this first novel highlights a character who has turned against this pan-galactic anarchist society, and worked for a religious extremist society sworn to destroy it. It's like Banks wanted to stress-test his perfect society by portraying one of its apostates first up.

Anyway, it's a great book, as the horrible Idirans and the Culture operatives race to rescue a stranded "mind" one of the super-powerful artificial intelligences which are at the core of the Culture.
