Accepting their company's assignment as medic and nurse on Glacialis, Shae and Bless find their welcome as frigid as the planet itself. Neither Adair, the mine's foreman nor Merag, his head of security make the men feel welcome or wanted.

When one of the miners seeks medical attention for an injury he doesn't want Adair to know about, Shae and Bless quickly find themselves investigating illegal activity at the mine, and embroiled in danger.

Shae finds himself falling in love with an undercover Ranger sent to investigate the mine, and he and Bless choose to help him.

Peril takes three forms, each different, but as deadly as the other.
