The Roots of the Mountains [EPUB ebook] 

The story is set in Burgdale, a small Germanic settlement in a valley at the foot of a mountain range, and the neighbouring woodlands, pastures and dales. The area is inhabited by the interdependent Dalemen, who are weavers, smiths, and traders, the Woodlanders, who are hunters and carpenters, and the Shepherds. Their society is challenged by disruptions from the outside world in the form of the Sons of the Wolf, the descendants of the Wolfings, and the invading Dusky Men (the Huns).
