The year is 2578 and immortals control the world. Brutal wars and endless genocide have reduced mankind to a handful of mountain tribes. In order to survive, humans infiltrate the eternal society as transient spies, hoping to uncover a means to regain control of the planet.
Jonas is a young transient deep undercover in downtown Seattle. He lives underground, works at night, and drinks his daily blood rations, just like any normal eternal. He is a model spy, but also an apostate among extremists, torn between ideologies (as well as lovers) from either side.
Allegiances are strained to the breaking point when Jonas bears witness to a violent death that rocks the eternal civilization to its core.
