A Christian Science Monitor Best Book of the Year Lilian Shang, a history professor in Maryland, knew that her father, Gary, had been the most important Chinese spy ever caught in the United States. But when she discovers his diary after the death of her parents, its pages reveal the full pain and longing that his double life entailed-and point to a hidden second family that he'd left behind in China. As Lilian follows her father's trail back into the Chinese provinces, she begins to grasp the extent of her father's dilemma-torn between loyalty to his motherland and the love he came to feel for his adopted country. As she starts to understand that Gary, too, had been betrayed, she finds that it is up to her to prevent his tragedy from endangering yet another generation of the Shangs. A stunning portrait of a multinational family, an unflinching inquiry into the meaning of patriotism, A Map of Betrayal is a spy novel that only Ha Jin could write.
