Purgatory Mount (2021)

Purgatory Mount unfolds across two seemingly unconnected timelines a near future United States in turmoil sounds familiar and a deep future setting aboard the forward a Starship crewed by near Immortal post-humans

I really enjoy Purgatory Mount I think Richard at vintage SF dnf did I re enjoyed it I thought it was very accessible as a young female protagonist bags of ideas and it's a good entry point if you're not used to the sort of high concept thing that he does but I thought it was excellent
