The book introduces us to a riotous cast of animals, and the scientists studying them, who are redefining the female of the species. Meet the female lemurs of Madagascar, our ancient primate cousins that dominate the males of their species physically and politically, the female albatross couples, hooking up together to raise their chicks in Hawaii or the meerkat mothers of the Kalahari Desert - the most murderous mammals on the planet. The bitches in the book overturn outdated binary expectations of bodies, brains, biology and behavior. The book will change how you think - about sex, sexual identity and sexuality in animals and the very forces that shape evolution
