In the last few decades a revolution has been brewing in zoology and evolutionary biology. Lucy Cooke introduces us to a riotous cast of animals, and the scientists studying them, that are redefining the female of the species.

The bitches in her book titled "Bitch" overturn outdated binary expectations of bodies, brains, biology and behaviour. Lucy Cooke's brilliant new book will change how you think - about sex, sexual identity and sexuality in animals and also the very forces that shape evolution.
