Exploring a range of international works such as films, streaming television series, a graphic novel, and a picture book, this open access book interrogates how, and to what extent, fairy tales are put to work for justice in the areas of environment and ecology, kinship and family, ability and disability, and sex and gender. As Bacchilega and Greenhill demonstrate, some 21st-century fairy tales channel the genre's wonder to offer otherwise possibilities for being and acting in the world that are not confined to socially sanctioned paths. Drawing on visual and audio-visual case studies of texts such as The Magic Fish, Julian Is A Mermaid, Pokot [Spoor], Graens [Border], The Dragon Prince, Gatta Cenerentola [Cinderella the Cat], and Sweet Tooth, they examine how the wonder and preternatural of fairy tales model a sustained desire to believe in and realize new ways of existence that have often been too easily dismissed. Guided by theories in fields including ecological, gender, disability, critical race, Indigenous, fantasy, posthuman, and adaptation studies as they intersect with folklore and fairy tale studies, this book examines how creators of wonder tales since the beginning of the new millenium have presented provocations around humans' political and social relations with nature and culture. Analyzing justice from a variety of positions and establishing how tales of the otherwise can develop optative thinking, Justice in 21st-Century Fairy Tales and the Power of Wonder refutes the conservative, patriarchal, and merely nostalgic Disnified narrative of the genre and insists on the power of wonder within and beyond fairy tales.
