Another book recommendation for Eclipse Phase: Pink Noise by Leonid Korogodski.
This is a gold mine for EP concepts and descriptions. The protagonist is an infomorph psychosurgeon, and the descriptions of him dancing his way around the damaged brain of a young girl provide great imagery of what might be involved. Plenty of other interesting ideas, from the mythology of the Martian blueberries, the roleplaying game themed technocratic caste societies that emerged from the singularity (not a bad description of how a hypercorp might work from the perspective of indentures), ZuluZionist Mars colonists, shapechanging warships, plasma going wild, the witchunts before the Fall, the wish virus and the Fairy...
In a way it almost feels like it is located in the same universe as Hannu Rajaniemi's "The Quantum Thief", but a few centuries earlier.
It also has lengthy endnotes where the author explains some of the science and linguistics he bases the story on. I don't buy all his interpretations of it, but it is interesting anyway. It is rare to find a poetic novel that also teaches you a bit about plasma physics and African mythology.
