We Are All Completely Beside Ourselves

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 is a chimp and, already, you aren't thinking of her as my sister. . . . Until Fern's expulsion . . . she was my twin, my fun-house mirror, my whirlwind other half. . . . 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.
