"Maura is doomed to starve. She's grown too tall. Her space station has no further use for her. Abandoned. Outcast. Crudrat. With only her crud-eating murmel and a fuzzy alien stranger to help, Maura must find a way to survive, before they catch her and blow what's left of her life into space. In the far future, on a space-port the size of a city, crudrats scrape out a meager living cleaning the great machines that generate usable power. Only children can safely traverse the cramped tunnels and the massive blades that harvest crud. But one misstep and a crudrat gets caught on a blade edge and killed. Like rats, they scurry through the bulkheads duty-bound to clean the air ducts so everyone else can breathe. But they become outcasts when they grow too big to be useful. Now one of the forgotten, Maura might just be able to turn rejection into escape--if she's resourceful enough."--Back cover.
