Roots of the Mountains [EPUB ebook] 
Wherein is Told Somewhat of the Lives of the Men of Burgdale, Their Friends, Their Neighbors, Their Foemen, and Their Fellows in Arms

Said to have been one of the source materials upon which J. R. R. Tolkien drew when creating his beloved Lord of the Rings series, The Roots of the Mountains is a classic fantasy that takes place on an epic scale. Two civilizations are drawn together by a pair of star-crossed lovers – and by the threat of an encroaching enemy that could destroy the world as they know it.
