Now Ganymede Deep Resources needs a crew for the first return descent into Jupiter's crushing depths, chasing a signal that has just started counting down for the first time in sixty years. Mireille takes the seat no sane person would want, falling through ammonia clouds, standing lightning, and an ocean of metallic hydrogen toward whatever took her brother's twelve-person crew — and gave nothing back but an empty room.
What waits at the bottom of the largest storm in the solar system isn't a grave. It's a question, asked patiently by something that has been watching this solar system since before her species learned to walk upright, waiting to see if anyone would finally arrive asking instead of taking.
But Mireille's own ship is carrying a weapon she doesn't know about. A second crew, blind to everything hers has learned the hard way, is descending right behind them. And somewhere below, an ancient patience is running out of time.
THE HOLLOW GIANT is a 56,000-word epic of first contact, institutional negligence, and the discipline of choosing to ask instead of take — for readers of The Expanse, Project Hail Mary, and Children of Time.
