Jessian Urania Darger is a kick-ass take-no-shit foul-mouthed too-smart-for-her-own-good sixteen-year-old girl with a chip on her shoulder. She and her daddy have been grifting their way across the verse for years. But when her daddy gets arrested for running crypto-credit scams, Jess is forced to get a job on Chadeisson Station as a roachrunner, fixing starships to survive.

She dreams of a better life, away from her corrupt daddy, so she's been saving up to buy a Spark Megahauler, a huge cargo ship, ever since she saw one in a printer catalog. She wants to run the long hauls, to sail alone into the black and never look back.

But when her daddy goes missing from prison, Jess realizes she just can't let him go, and she makes it her life's mission to find out where he's gone. In an odyssey that takes her across the galaxy, Jess encounters vanished planets, strange societies, inscrutable alien gods, and mind-bending secrets that may change humanity's path forever.
