A landmark 1970s experiment becomes a real-life thriller in Susannah Cahalan's The Great Pretender. Stanford psychologist David Rosenhan and seven other well-adjusted people had themselves committed to psychiatric institutions in order to investigate the care that patients received. Their findings changed the field of psychiatry, but it's the story of what happened behind closed doors that adds an extra layer of intensity to this already edge-of-your-seat read.
