- Three loosely linked hard science fiction novels by Greg Egan, connected by ideas rather than characters: what observation, identity and consciousness mean if physics is taken seriously.
- Each stands alone.
- Permutation City, about people who live on as computer simulations, is the most read and the best rated, and the usual way in.
- Expect real physics and mathematics on the page.
