Trolls [PDF ebook] 

For centuries, the myths of trolls have fascinated and frightened people young and old. Originating in the time of the Vikings, trolls have been constant figures of mythology since the very first troll story. Their lore has evolved and developed over time, but their representations, especially across Scandinavian culture, have lasted to the present day. This book explains the history of troll lore throughout the ages, examines other troll folktales from around the world, and even explores how the troll persists in today’s society.
