Grey, by Jon Armstrong. This is a damned fine debut novel. Set in a satircal, class-striated future in which those who have it all are slaves to the need to be constantly fashionable (or die trying), it features romance, corporate warfare, drugs, and some great characters.
Grey defies easy description, but it's fun and highly recommended.

Blindsight, by Peter Watts. Watts continues to blow me away. I adored the
Rifters saga, and
Blindsight contains much of what makes that series good: phenomenal scientific ideas, great characters, and some amazing twists. In the first 100 pages, Watts introduces deliberately-induced MPD, an earth in which interest in "real" sex has faded as virtualized sex has taken over (with the resultant decrease in population growth), a protagonist missing half his brain, a resurrected (and largely scientifically-sound) vampire, and a first contact mission. Throw in major explorations of neurological functions (the title refers to a condition in which the brain can see something and might even react to it, but the person is not consciously aware of their ability to see it) and evolutionary strengths and weaknesses (for humans and aliens alike), and you've got a book that's nothing short of brilliant. I haven't read the Flynn or Vinge books yet (both are on order at my library), so I won't say that it would be a crime if this didn't win the Hugo, but I'd be happy to see it get the recognition it deserves. This is an amazing work. Highly, highly recommended.
