The Comet Harvester's Daughter

About this book:

On the rust-bucket harvester *Cetus-Four*, seventeen-year-old Mara Vance has spent her life calculating trajectories through the dark while her father, Tark, chases the deuterium hauls that keep their ship from the scrapyard. When they anchor onto comet 88P/Howell for a routine seventy-five-day harvest, Mara’s sensors find something that shouldn’t exist: a localized heat source forty meters down, perfectly symmetrical, venting a vapor that moves like smoke instead of gas. The third anchor strikes black ice that fractures like blown glass—and reveals a straight, deliberate line cutting through four-billion-year-old strata.

With the company threatening foreclosure and the comet waking up around them, the crew drills deeper. What they uncover isn't fuel. It's a structure vast enough to dwarf their ship, sealed in the heart of a wandering mountain of ice. As the nucleus heats toward perihelion, venting toxic plumes and shifting its spin, Mara and her father must navigate mutinous crewmates, failing hardware, and the terrifying realization that they have breached a containment that has held since before humans walked upright. Something is waking up in the dark—and it has been waiting for the thaw.

*The Comet Harvester's Daughter* is hard science fiction at its most visceral: a blue-collar space opera where every bolt, every burn of hydrazine, and every fraction of a degree on a spectrograph matters. For readers who love the industrial grit of *The Expanse* and the ancient mystery of *Rendezvous with Rama*, this is a debut that plunges you into the cold, the dark, and the weight of discovery.
