‘She’s gone, that’s all, and though there’s no retrieving her I’d like to make sense of who she was and what she became. It wasn’t just that she changed over time. She could change from day to day. Drink made it worse but the origins went deeper. You never knew which you’d get, the kind and loving Gill or her doppelgänger. Two sisters.’ Blake Morrison has lost a sister and a half-sister in recent years. Both are the subjects of this remarkable and heart-breaking memoir, along with a forensic examination of sibling relationships in history and literature. Blake’s sister Gill struggled with alcoholism for a large part of her life, and her shocking death is the starting point for Two Sisters. Blake returns to their childhood to search for the origins of her later difficulties, and in doing so unearths the story behind his half-sister, Josie. As he unravels these narratives, Blake deals movingly in the guilt and shame that will be familiar to every person who has struggled with addiction in their family. He is unflinching in doing so, and the result is a book which provides testament to that common struggle, as well as acknowledging the complex, hidden forces on which all our lives are based. Two Sisters is the extraordinary new memoir from the chronicler of human frailty, Blake Morrison.
