Two Jeff Noon novels: Nymphomation and Automated Alice. Both rather brilliant, hard to categorise and highly recommended.
Also, The Chronoliths by Robert Charles Wilson - an excellent SF novel marred by two things: Wilson's ability to research the science aspect is sadly not matched by his research into real life cultures. A main character is one Sulamith Chopra, a scientist whose family hails from Madras, the city where I was born. Chopra is an extremely unlikely nickname for a person from Madras, and I have never, ever, met anyone with the name Sulamith. Secondly, I am just fed up of books where Asia, Africa, the Middle East are all reduced to rubble, while Europe and North America remain relatively unscathed. Gahhhhh. Nevertheless, a great read, awesome concepts and masterful prose. Sadly, for all his insight and imagination, Wilson cannot quite escape his cultural myopia. This is why I tend to prefer far-future or outer-space SF.
Now reading: Angelica Gorodischer's Kalpa Imperial, supposedly this leading Argentinian fantasist's masterpiece, translated by one Ursula Le Guin. Quite amazing so far, more magic realism than generic fantasy if you ask me, but hey, whatever.
