She's smart, vulnerable, innocent, and culpable. Over the years, she's managed to block a lot of memories. Rosemary was not yet six when Fern was removed.


She was my twin, my funhouse mirror, my whirlwind other half, and I loved her as a sister." But until Fern's expulsion, I'd scarcely known a moment alone. I tell you Fern was a chimp and already you aren't thinking of her as my sister. "It's never going to be the first thing I share with someone. "I spent the first eighteen years of my life defined by this one fact: that I was raised with a chimpanzee," she tells us. Meet the Cooke family: Mother and Dad, brother Lowell, sister Fern, and our narrator, Rosemary, who begins her story in the middle. But that exception is the beating heart of this extraordinary novel.

From the New York Timesbestselling author of The Jane Austen Book Club, the story of an American family, middle class in middle America, ordinary in every way but one.
