Baltimore, before the stars. Amos Burton - then still going by a different name - is a young man surviving in a city where the basic income has made unskilled labour worthless and crime is one of the few remaining economies. The story of how Amos became Amos, and why he left Earth and never looked back. Technically a prequel but best read after Nemesis Games, when you already know who Amos is and what this backstory costs him.
