sses, elves, monsters, and goblins to giants, glass slippers, poisoned apples, magic keys, and mirrors, the characters and images of fairy tales have cast a spell over readers and audiences, both adults and children, for centuries. These fantastic stories have travelled across cultural borders and been passed on from generation to generation, ever-changing, renewed with each re-telling. Few forms of literature have greater power to enchant us and rekindle our imagination than a fairy tale.

But what is a fairy tale? Where do they come from and what do they mean? What do they try and communicate to us about morality, sexuality, and society? The range of fairy tales stretches across great distances and time; their history is entangled with folklore and myth and their inspiration draws on ideas about nature and the supernatural, imagination and fantasy, psychoanalysis, and feminism.

Marina Warner has loved fairy tales over a long writing life and in Once Upon a Time, she explores a multitude of tales through the ages, their different manifestations on the page, the stage, and the screen. From the phenomenal rise of Victorian and Edwardian literature to contemporary children's stories, Warner unfolds a glittering array of examples, from classics such as Red Riding Hood, Cinderella, and The Sleeping Beauty, the Grimm Brothers' Hansel and Gretel, and Hans Andersen's The Little Mermaid, to modern-day realizations including Walt Disney's Snow White and gothic interpretations such as Pan's Labyrinth.

In 10 succinct chapters, Marina Warner digs into a rich hoard of fairy tales in their brilliant and fantastical variations in order to define a genre and evaluate a literary form that keeps shifting through time and history. Her book makes a persuasive case for fairy tale as a crucial repository of human understanding and culture.
