The Wicked Sister by Karen Dionne
Two generations of sisters. An unthinkable crime. A secret that could ruin a family. Most of us have read about or known of people who have been imprisoned unjustly for years or even decades.
But what if you discovered that you had unjustly imprisoned yourself? After spending 15 years in a mental hospital as a self-inflicted punishment for her childhood crime, a young woman learns that she might not have killed her mother as she has always believed.
