I'm looking for sci-fi novel title, hopefully someone has better memory than me.
A female protagonist in a world (all is actually set in Solar System) where humans are nearly/extinct (I recall 'pink goo' as a term for human flesh) and the remaining beings (created by copying/cloning humans hundred of years ago) live in feudal hierarchy with slave labour etc. She is travelling through Solar system adapting her body as needed in different environments (low temperatures on dark side of Mercury). Soul/memory chips. Arbeiters.
