Catherine Ling: raised on the streets of Hong Kong, she has been a shadowy CIA operative since she was fourteen years old. There are only a few things in life she cares for. One is her son, kidnapped when he was two. Catherine has only recently been reunited with him and the vow of her heart is never to let him face danger again. The other is her mentor, Hu Chang. Mysterious, brilliant, and deadly, Hu Chang taught Catherine everything she knows and she is loyal to him. Now Hu Chang is calling Catherine to a new task: rescue an imprisoned journalist in Tibet -- a woman who has been subjected to unspeakable horrors. Her connection to Hu Chang is unknown. What's also unknown is that Catherine will be going up against a man whose crimes have stretched back into this area for forty years. Is Catherine being used as a pawn by Hu Chang? Can she save a woman she's never even met? And will either of them live to see tomorrow?
