Citizen of the Galaxy

SLAVE: Brought to Sargon in chains as a child -- unwanted by all save a one-legged beggar -- Thorby learned well the wiles of the street people and the mysterious ways of his crippled
master . . .
OUTLAW: Hunted by the police for some unknown treasonous acts committed by his beloved owner, Thorby risked his life to deliver a dead man's message and found himself both guest and prisoner aboard an alien spaceship . . .
CITIZEN: Unaware of his role in an ongoing intrigue, Thorby became one of the freest of the free in the entire galaxy as the adopted son of a noble space captain . . . until he became a captive in an interstellar prison that offered everything but the hope of escape!
