Kade Whitehawk had two strikes against him in the Space Service. First, he had bungled his assignment on the planet Lodi. Second, he believed all creatures had a right to freedom and dignity - and having such opinions was strictly against the rules.
But when he ws assigned to Khot, he found the Ikkinni there - tortured yet defiant slaves of a vicious tyrant race.
