Saturn's Children by Charles Stross

A Space Opera

In a future where humanity has become extinct, the universe is populated by sentient robots who were once created to serve their human masters. The story follows Freya Nakamichi-47, a gynoid designed for companionship, as she navigates a complex interplanetary society filled with political intrigue, espionage, and existential dilemmas. As Freya embarks on a perilous journey across the solar system, she grapples with her own identity and purpose in a world where the absence of humans has left a void in the lives of their mechanical successors.
