The Armies of Memory (SciFi)

Giraut Leones, special agent for the human Thousand Cultures’ shadowy Office of Special Plans, is turning fifty--and someone is trying to kill him. Giraut’s had a long career; the number of entities that might want him dead is effectively limitless. But recently Giraut was approached by the Lost Legion, an Occitan underground linked to an alliance of illegally human-settled worlds beyond the frontier.
