Really enjoyed this. Wish Bookwyrm allowed for half stars - would be 4.5 here. So many interesting ideas, explored well. Always kept me guessing what was happening, and the story unwound at a (mostly) pleasing pace. A slow pace, mind - not one for action-science fiction fans; this is very thinky, philosophical stuff.

A couple of the chapters didn't quite work for me - more narrative background than story, they contributed to the overall understanding but I found them harder to get through than the rest - but Tchaikovsky really does explore some fascinating concepts here and I recommend this one for anyone into this slower style of science fiction.

@picard Just a quick, small note. You can get half stars by clicking star twice - it fills on first click, half on second.
