THIS IS A WORK OF NONFICTION, AND I HAVE USED REAL NAMES WITH one exception: Polat. The pseudonym is used at his request, because of political sensitivities in the People’s Republic of China. This book was researched from 1999 to 2004, a period whose events are still resonating. I expect that in the future we will learn more about these occurrences, and my depiction is not intended to be comprehensive or definitive. My goal has been to follow certain individuals across this period, recording how their lives were shaped by a changing world.
