I'd love to read Pump Six (the collection - I've read the excellent title story) but it's an expensive hardcover not published in the UK (so I can't get it out of the library), and I'm on book-buying budget this year. If people want to go ahead with this, just ignore me - I won't be able to take part, that's all.
As it's just come up in the cantina, though I know it's been a possible before - how about Stanislaw Lem's Solaris? ETA: Just seen that Fenika's already nominated it!
