The popularity of fantasy sub-genres, particularly those like Sarah J. Maas’s ‘A Court of Thorn and Roses’, has sparked debate over the appropriation of Welsh culture. While some celebrate the spread of Welsh influences, critics argue that it risks misrepresenting the complexity of Wales. Bookseller Bethan Hindmarch and professor Dimitra Fimi emphasize the importance of authenticity and the need for sensitivity in depicting Welsh culture in fantasy literature, cautioning against a homogenized view of Celtic traditions.
