The New York Times bestselling author of The Jane Austen Book Club introduces a middle-class American family that is ordinary in every way but one in this award-winning novel.

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.

"A gripping, big-hearted book...through the tender voice of her protagonist, Fowler has a lot to say about family, memory, language, science, and indeed the question of what constitutes a human being."--Khaled Hosseini
