Published by Gollancz (London) in 2002, this is a confirmed first edition hardcover, signed by the author on the title page. Reynolds’ work is widely recognized for its combination of hard science fiction and large-scale space opera, and signed first editions from this series are collected as a cohesive set, particularly alongside Revelation Space and Chasm City.
