Reading Revelation Space on my Kindle and The Divine Comedy in hard copy.
I will probably go on to read Dark Places and Horns next, as those are the only books by those two authors that I have not read yet.
I'm just finishing up Pushing Ice, it was weird at first but I'm really enjoying it now. I guess you could say a lot of his books are weird at first in a way though...
I read Chasm City before that. Now I'll probably do Revelation Space since I have the series already and you've reminded me of it.
