Emily Devenport’s Medusa Uploaded is the first volume in her generation ship series, the Medusa Cycle.
Olympia and Titania are two vast generation ships, dispatched on a long, slow journey to another star system. This was lifetimes ago. Olympia is still functioning, but poor Titania is lifeless wreckage tumbling across the stars, the victim of an act of sabotage. Oichi was born on Titania but was fortunate enough to emigrate to Olympia before Titania’s destruction. The rest of her family was not so lucky.
Oichi isn’t one of the ruling Executives; she’s a so-called worm. Her lot is to work hard for her whole life, hoping that no Executive will order her tossed out an airlock. Oichi’s fortune turns sour. Suspected as a potential dissident, she is cast out into the interstellar cold.
This is not the end of her story.
