Oh Mesmerist From Mimas!

Blaster Bill Bailey has prospected asteroid belts and survived more close calls than any spacer ought to. But nothing in his years among the rocks prepared him for Mimas. The moon's native creatures possess a talent that's both terrifying and irresistible: they can reshape human behavior with a thought, turning the most hardened prospectors into trembling servants or fearless berserkers. When Bill stumbles into their territory, he becomes a pawn in a game played across the solar system, where interplanetary commerce and alien psychology collide. The creatures of Mimas don't want gold or territory. They want something far more strange: they want to understand humanity, even if understanding means control. Bill must find a way to broker peace between human greed and alien curiosity before his own mind becomes a weapon pointed at everything he's ever cared about. This is classic golden age SF at its most inventive, where the real frontier isn't space but the boundaries of consciousness itself.
