The New York Times bestselling author of The Jane Austen Book Club introduces a middle-class American family, ordinary in every way but one.

Meet the Cooke family: Mother and Dad, brother Lowell, sister Fern, and Rosemary, who begins her story in the middle. She has her reasons. “I was raised with a chimpanzee,” she explains. “I tell you Fern was a chimp and already you aren’t thinking of her as my sister. But until Fern’s expulsion … she was my twin, my funhouse mirror, my whirlwind other half and I loved her as a sister.” As a child, Rosemary never stopped talking. Then, something happened, and Rosemary wrapped herself in silence.

In We Are All Completely beside Ourselves, Karen Joy Fowler weaves her most accomplished work to date—a tale of loving but fallible people whose well-intentioned actions lead to heartbreaking consequences.
