The Little Girl on the Ice Floe author Adélaïde Bon explores a topic that has long fascinated her: the history of witches. Beginning with the witch-hunts of the Renaissance, she considers how depictions of witches have evolved, examining nasty archetypes portrayed by writers like Roald Dahl, and their counterparts as imagined by the likes of Babette Cole. Adélaïde explains how witches have empowered her, and how writing itself is like brewing potions with words.
