Four years after their bitter divorce, Claire and Aaron Litvak get a phone call no parent is prepared for: their 22-year-old daughter Lindsey, teaching English in China during a college gap year, has been critically injured in a hit and run accident. At a Shanghai hospital they wait at her bedside, hoping for the best and preparing for the worst. The accident unearths a deeper fissure in the family: the shocking event that ended the Litvaks' marriage and turned Lindsey against them. Estranged from her parents, she has confided only in her younger sister, Grace, adopted as an infant from China. As Claire and Aaron struggle to get their bearings in bustling, cosmopolitan Shanghai, the newly prosperous "miracle city," they face troubling questions about Lindsey's life there, in which nothing is quite as it seems.
