Reading Permutation City changed the way I think, and I’ve been loving working my way through everything Greg Egan. It’s almost as if its a new literary genre - Computer Science Fiction.
I was on this exact same journey, so our taste must be similar. Love his stuff.
Just in case our taste is VERY similar, I have really enjoyed every book I've read so far except the middle book in the Orthogonal series.
The first was great, third was back in form. I would recommend, if you are reading the second one, and start to wonder why you should press through, just skip to the third one.
I'm not really qualified to make any judgements about the overall quality of it, but it's moreso the tone of it that I am talking about. I wonder if he was going through something when he wrote that one or something.
