The story transitions to a pure quest.
Betrayed by a fool, Sarah is marooned in space. The excitement and wonder of her first voyage turn into terror, depression, and hopelessness as she scrabbles and scrapes to survive the trip and return her ship and crew to civilization. Jimmy expands his reach and continues to search for her. His obsession becomes his job, then his career, then his life.
He rescues many people from gruesome, implacable death in the frozen vacuum of the Black - but not Sarah.
