I’m a Greg Egan fan. Schild’s Ladder and Teranesia are top of mind at the moment. 

Vacuum Diagrams by Stephen Baxter. It’s linked short stories set in a larger collection I haven’t read, but which sounds promising. 

I’ll post more if I think of more, but it’s been way too long since I read a sci fi book… I have been missing it!

All these Nostr folks loving TBP makes me think about rereading the first and reading the sequels as well… 

 Seconding Greg Egan. For the cypherpunk (like calle) I'd particularly recommend Permutation City. Diaspora is also a favourite. Agree on Schild's ladder also. 

 Egan is absolutely amazing. 

 Came here to say Greg Egan.
