A Helium-3 miner named Crater makes a treacherous journey through space to find a mysterious and priceless treasure.
It's the 22nd Century and a tough, pioneering people are mining the moon to produce energy for a desperate, war-torn Earth. Crater, an orphan, loves his life in Moontown, a frontier mining settlement. Not quite sixteen-years-old, he is already a seasoned Helium-3 miner with hopes to be a foreman on the scrapes someday.
But the man who owns the mine has a different plan for Crater and another orphan, a young girl with a violent past named Souza. With Souza and his gillie-a sentient and sometimes insubordinate clump of slime-mold cells-Crater must venture forth on a forbidding river of dust. Together, they'll cross the hostile Lunar terrain before vaulting in to the far reaches of space.
Danger, adventure, and discovery await them as Crater, the gillie, and Souza use their wits and courage to find a mysterious treasure.
