Xin Tian quietly glanced at her family. Her father, the factory director, was packing for a training course at school. Her mother, celebrated by the public as a shining example of revolutionary opera, was working on a new book. Her older brother, a company commander home on leave from the army, was unpacking local specialties he'd brought back from his post. Her sister... Her sister wasn't home. She was in the capital, representing the school's outstanding students at an exchange program. Xin Tian: So the novels really are all lies.
