Charles Stross. One of the main authors in the hard sci-fi genre. Felt it I should check him out. Unfortunately, unlike Alastair Reynolds or Iain Banks, Stross seems to utterly lack the ability to make you care about the people in his books. Read about half-way through and just realized "I don't care how this ends..." and put it down.
