Terminal World is a sci-fi novel by author Alastair Reynolds. It's a stand-alone story, distinct from his usual Revelation Space universe. Taking place thousands of years into a bleak future, the novel concerns the last remaining city of mankind, the strange reality warps around it that limit the level of technology people can build, and a doctor's exile from that city into the wastelands outside. Then one day another Angel falls to the Neon Heights. Mistaken for dead, it's taken to Quillon whereupon the "dead" angel wakes up and delivers a warning: get out of Spearpoint while you still can.
