How about this sentence, lifted from the back cover, which perfectly summarises the opening scene: 'A man, once called Jimmy, now calls himself Snowman and lives in a tree, wrapped in old bed sheets, eating mangoes'. Awesome. Jimmy lives in some kind of post-apocalyptic world, although the exact nature of the apocalypse is revealed tantalisingly slowly throughout the story. Really, in Oryx and Crake you get a double dyslit: you get Jimmy now as Snowman, in the wastelands of earth, and you get Jimmy as Jimmy, growing up in a strange, strange society. Genetic modification not only takes place, but it essentially rules society. Get a job working for OrganInc or HelthWyzer and you are set for life. (OrganInc - the guys that brought you the pigoon - kind of like a pig, but fatter to allow space for the 4 or 5 human kidneys they've got growing inside them). Hungry? Try a bucket of chickie-nubs - kind of like chicken nuggets, except the thing they came from looks nothing like a chicken as we know it.
The great thing about this dyslit is that none of the technology is really out-there fantastic. Instead, what has changed (and messed up society a lot) is genetic modification. This is the first book I ever read and thought 'That was a ten out of ten.' While opinions about Margaret Atwood can be polarising, I think everyone who want a fascinating book to start (or just develop) a dyslit obsession needs to read this one. And just to tantalize you a little bit more - I think Oryx and Crake has THE best ending of a book I have ever read.
