House of Suns by Alastair Reynolds

My Santa must have noticed that I'm into sci-fi as he/she sent me this awesome book. The concept sounds really cool and I can't wait to get stuck into it.

UPDATE:

Two more books just arrived:

A Deepness in the Sky by Vernor Vinge Spin by Robert Charles Wilson

All new to me but all award winners with intriguing concepts. Thanks, santa! :)
