Terminal World is the latest book by Alastair Reynolds. The book is set some time in the future in a time when humans are struggling to survive on a cooling planet where zones restrict where advanced technology or even biological life can survive. The main human city is located on the surface of a large spiralling spire reaching out into space. Both the zones and the spire are remnants of earlier times when humans were more technologically advanced. That time is gone, and little knowledge remains of this time. Most of humanity live in primitive zones where only primitive machinery can function.
The main character of the book, Quillon, is an angel. Angels are descendants of some modified and enhanced part of the human race. They can only survive in the zones that allow the highest level of technology. Quillon has been modified to serve as an infiltrator in the lower level zones, and now someone is out to kill him. The story first takes us through his flight, and then we follow him as he learns about the story of humanity and the remnants of ancient technology.
As usual, Reynolds has written a magnificent story. Very imaginative. However as too often with his books, the ending feels a bit rushed and too much left to be explained. Still, a very good read.
