Decoding Andean Mythology analyzes native Andean oral traditions spanning five centuries. Based on twenty years of research and a wide range of scholarship, this book departs from the Cuzco-centered focus of many published Andean narratives and includes myths, stories, and folktales from diverse regions and ethnic groups. Among them are full translations of thirty-two ancient and modern Native Andean stories. Colorful illustrations and a comprehensive glossary of Quechua, Aymara, and Spanish loan words supplement the text.

In an accessible and engaging discussion suitable for students, the author explores a number of recurring themes and characters in Andean stories. These include shape-shifting animals, the inversion of time-space (pachacuti), anthropomorphic and supernatural beings, and conflicting attitudes toward sexuality. The text also presents a fresh perspective on traditional, non-Western concepts such as huacas (sacred objects and places), suggesting that some serve as portals between the natural and supernatural worlds. A lengthy chapter on social protest that explains the rise of indigenous movements in the Andes and highlights the contemporary use of Native Andean folktales as an avenue for social and political dissent.
