Just wanted to say, for anyone who's unfamiliar with it, The Raw Shark Texts is probably one of the greatest books I've read in a long time - I read it in a day and a half because I couldn't not read it (I'd have finished sooner but I had a migraine to sleep off).
Anyway, the less you know about it the better, but I will say don't attack it unless you have the capacity for some rather abstract thinking...
