As a girl in Indiana, Rosemary, Fowler’s breathtakingly droll 22-year-old narrator, felt that she and Fern were not only sisters but also twins. So she was devastated when Fern disappeared. Then her older brother, Lowell, also vanished. Rosemary is now prolonging her college studies in California, unsure of what to make of her life. Enter tempestuous and sexy Harlow, a very dangerous friend who forces Rosemary to confront her past. We then learn that Rosemary’s father is a psychology professor, her mother a nonpracticing scientist, and Fern a chimpanzee. Fowler, author of the best-selling The Jane Austen Book Club (2004), vigorously and astutely explores the profound consequences of this unusual family configuration in sustained flashbacks. Smart and frolicsome Fern believes she is human, while Rosemary, unconsciously mirroring Fern, is instantly tagged “monkey girl” at school. Fern, Rosemary, and Lowell all end up traumatized after they are abruptly separated. As Rosemary—lonely, unmoored, and caustically funny—ponders the mutability of memories, the similarities and differences between the minds of humans and chimps, and the treatment of research animals, Fowler slowly and dramatically reveals Fern and Lowell’s heartbreaking yet instructive fates. Piquant humor, refulgent language, a canny plot rooted in real-life experiences, an irresistible narrator, threshing insights, and tender emotions—Fowler has outdone herself in this deeply inquisitive, cage-rattling novel. --Donna Seaman
