A collection of chilling narratives rooted in the dark folklore and atmospheric landscapes of Wales, this anthology explores the thin boundary between the mundane and the supernatural. The stories follow various protagonists who encounter inexplicable phenomena, ancient curses, and malevolent entities lurking within the rugged terrain. These characters must navigate psychological dread and physical peril as they confront forces that defy rational explanation. The narrative framework shifts between traditional oral storytelling styles and more structured, suspenseful prose to heighten the sense of unease.

This anthology is regarded as a significant contribution to the regional horror genre, effectively capturing the specific flavor of Welsh gothic literature. Readers often note the collection's ability to balance traditional folklore with modern narrative sensibilities, creating a cohesive yet varied reading experience. The editorial selection by John Christophe and Glyn Jones is frequently praised for its curation of stories that prioritize mood and setting. The work serves as a primary reference for those interested in the intersection of Celtic mythology and the horror tradition.
