Young Rue Cassels of the Cycler Compact- a civilisation based around remote brown dwarf stars - is running for her life from her bullying brother, Jentry. Fleeing in a single person spacecraft, she spots a distant, approaching object, and stakes a legal claim to it. It is not the valuable comet she has hoped for, but something even more wonderful, a billion year-old alien starship. Permanence is the story of Rue's quest to visit and claim this ship and its treasures, set against a backdrop of interstellar intrigue and warring empires.
