In 1967, after a session with a psychiatrist she'd never seen before, 18-year-old Susanna Kaysen was put in a taxi and sent to McLean Hospital to be treated for depression. She spent most of the next two years on the ward for teenage girls in a psychiatric hospital renowned for its famous clientele - Sylvia Plath, Robert Lowell, James Taylor and Ray Charles. An unflinching work that asks questions about our definitions of sane and insane, Kaysen's memoir encompasses horror and razor-edged perception while providing vivid portraits of her fellow patients and their keepers.
