Via just about everyone else , here'sLocus Online: 2004 Recommended Reading.
The problem with a lot of these lists is that the books are only out in hardback. And I just can't afford to buy everything in hardback. So what I'd like to read when they're out in paperback (some of them may be now?)...
# The Algebraist, Iain M. Banks (Orbit)
# Stamping Butterflies, Jon Courtenay Grimwood (Gollancz)
# Newton's Wake, Ken MacLeod (Orbit; Tor)
# White Devils, Paul McAuley (Simon & Schuster UK; Tor)
# Century Rain, Alastair Reynolds (Gollancz; Ace 2005)
# Forty Signs of Rain, Kim Stanley Robinson (HarperCollins UK; Bantam)
# Air, Geoff Ryman (St. Martin’s)
# The Baroque Cycle: The Confusion; The System of the World, Neal Stephenson (Morrow)
# The Zenith Angle, Bruce Sterling (Del Rey)
# Iron Sunrise, Charles Stross (Ace)
and I really should finish reading Eastern Standard Tribe, Cory Doctorow (Tor) but I have it on my computer in pdf and so never get around to it.
Of course, that will take me all year to read those. So little time...
