"The Horse Goddess" starts with young Epona coming to age in her tribe in ancient Ireland. Epona is, in Celtic mythology, the horse goddess. Morgan Llywelyn takes the story of Epona and expands it and tells the story of how a regular young woman could come to be revered as a goddess. The story isn't written in the traditional sweeping fantasy manner. Rather, "The Horse Goddess" reads like listening to a story. I can just imagine sitting around a fire listening to the village wise woman telling this story and the children sitting at her feet, listening with wide eyes. Epona has begun to exhibit magical abilities and the village's Druid priest, Kernunnos, desires to teach her. But something in Epona makes her rebel against Kernunnos and his unnatural ability for shape-changing. Kernunnos is obsessed with Epona and her powers, and when she flees her tribe rather than submit to becoming a Druid, he follows her all the way to the Scythians, which is where she finally ends. She exhibits an unusual ability of being able to communicate with animals, notable horses. The Scythians are a very horse-centered tribe, and Epona creates a place for herself in a society where women are little more than property.
Llywelyn's story of Epona is a must read for people that are interested in Celtic mythology and ancient Ireland. Llywelyn is an amazing talent, and being interested in the ancient Celts and Ireland, I plan on reading many more of her books. She brings ancient Ireland to life, and adds depth and detail to Celtic myths.
