A map of betrayal

"A spare, haunting tale of espionage and conflicted loyalties that spans half a century in the entwined histories of two countries--China and the United States--and two families as it explores the complicated terrain of love and honor. When Lilian Shang, born and raised in America, discovers her father's diary after the death of her parents, she is shocked by the secrets it contains. She knew that her father, Gary, convicted decades ago of being a mole in the CIA, was the most important Chinese spy ever caught. But hisdiary--an astonishing chronicle of his journey from 1949 Shanghai to Okinawa to Langley, Virginia--reveals the pain and longing that his double life entailed."--Provided by publisher.
