In the Second Starfaring Age, humans travel the universe via a technology they barely understand, propelled by a space drive consisting of mysteriously complex mechanisms and, symbiotically linked to it, a living woman, the Void Pilot.

Pilots are rare, and the ability to be a Pilot also entails physical wasting and a shortened life. But Pilots live only for the timeless moments of Transition, when their ships cross the emptiness of space in an instant. Now Void Pilot Dominique Alia Wu has begun to catch a glimpse of something more, something transcendent in that eternal moment... and she needs the cooperation of her Captain to achieve it permanently. Even at risk to the survival of the Ship.
