The acclaimed author Wally Lamb is the author of I Know This Much Is True. In this story an unmarried woman with a cleft lip has a pair of identical twins after her father has died. One of the twins grows up to have paranoid schizophrenia. His brother tries to help him. His mother marries a man who abuses all three of them. In 1990 the brother with mental illness takes a military knife to the library and cuts off one hand. He gets sent to a forensic hospital for a year. Eventually he gets released and goes to a group home. This was a long book. I spent over 13 hours reading it on my phone. Excellent story though.
