Fern Schumer Chapman understands the pain of sibling estrangement firsthand. For the better part of forty years, she had nearly no relationship with her only brother. Her grief and shame were devastating and isolating. But when she tried to turn to others for help, she found that a profound stigma still surrounded estrangement, and that very little statistical and psychological research existed to help her better understand the rift that had broken up her family. Brothers, Sisters, Strangers is a thoughtfully researched memoir that illuminates both the author’s own story and the greater phenomenon of estrangement. Chapman helps readers work through the challenges of rebuilding a sibling relationship that seems damaged beyond repair. It is at once a detailed framework for understanding sibling estrangement, a beacon of solidarity and comfort for the estranged, and a moving memoir about family trauma, addiction, grief, and recovery.
