So in the pub last night a friend was telling me about the most amazing sci fi book by a Japanese author. Having had one too many all I can remember is a brief synopsis of the story. I hope that someone can help a newbie!!! The story is told in alternative chapters. The odd chapters concern a world where two companies rule everything, making information the most powerful thing to own. The only way to protect their information is by hiring people who have managed to train their brains to take in the information sub-conciously and then transfer it from their left side of their brain to their right side. Once scrambled on their right side they come out of the fugue like state and find that they have a sheet of writing/drawings in front of them, obviously the only person capable of deciphering this is the guy who has 'encrypted' it. The even chapters concern a city that is surrounded by the highest inpenatrable(?) wall that can not be scaled or destroyed. When the 'gate keepers' open the doors of the city for you they cut off your 'shadow' that leaves you (Pullman anyone?) and in turn you are imprisoned in the city. The city contains unicorns. Thats it guys!! Thats all I can remember, but it sounds great and I would love to read it. Thanks in advance.
