The Glass Castle is a remarkable memoir of resilience and redemption, and a penetrating look into a family at once deeply dysfunctional and uniquely vibrant. When sober, Jeannette's brilliant father captured his children's imagination, teaching them physics, geology, and how to embrace life fearlessly. But when he drank, he was dishonest and destructive. Her mother was a free spirit who hated anything to do with domesticity. The Walls children learned to take care of themselves. They fed, clothed, and protected one another, and eventually found their way to New York. Their parents followed them, choosing to be homeless even as their children prospered.
