A collection of traditional Welsh tales centers on the legendary Eagle of Gwernabwy and other figures from ancient folklore. These stories follow various protagonists navigating a landscape defined by mythic creatures, ancient kings, and the shifting boundaries between the mortal and supernatural realms. The narrative framework utilizes a series of episodic accounts, drawing upon the oral traditions of Wales to explore themes of wisdom, hubris, and the passage of time. Each tale presents distinct logical constraints rooted in the specific rules of Welsh mythology, where natural elements often possess agency and ancient pacts dictate the fates of men.

Readers often note the collection's success in preserving the distinct flavor of Welsh oral tradition through accessible prose. Discussion frequently centers on the atmospheric quality of the settings, which effectively grounds the more fantastical elements of the myths. Critics highlight the balance between the brevity of the individual tales and the depth of the cultural history they represent. Many readers appreciate how the book serves as an introduction to regional folklore without requiring prior knowledge of the subject matter. The pacing remains consistent throughout, allowing for a steady engagement with the various legends presented in the volume.
