Sci-fi novels

Recommend me some sci-fi novels, you puny faggots.

What are some? Please try to only name books with AT LEAST SOMEWHAT decent prose. (That completely excludes Clarke and Douglas Adams, obviously.)

Any of Stephen Baxter's works. I started off with Manifold: Space, part of a trilogy of novels that each occur in their own universe and attempt to answer the Fermi Paradox. Other awesome works are the Xeelee Sequence, which covers a vast war throughout time and space with the highly misunderstood Xeelee, and a currently unnamed disaster series which covers the end of the world and what happens after. Hit his wiki entry for the proper order of most of his works--though for the Manifold trilogy, order isn't important, and the Xeelee Sequence covers such vast tracts of time that you may as well hit in whatever order you can find them.
He also wrote, with Arthur C. Clarke, A Time Odyssey, three books that are a kind of alternate universe Space Odyssey--they were the very last things Clarke wrote before his death.
Oh, and he wrote an authorized sequel to The Time Machine, called The Time Ships, which was epic. So--let's face it, authorized to write a sequel to one of the greatest time travel stories of all time, worked with one of the biggest names in science fiction. He's worth your time.
