The Story of Kullervo
Brought up in the homestead of the dark magician Untamo, who killed his father, kidnapped his mother, and tried three times to kill him when he was still a boy, Kullervo is alone save for the love of his twin sister, Wanona, and the magical powers of the black dog Musti, who guards him. When Kullervo is sold into slavery he swears revenge on the magician, but he will learn that even at the point of vengeance there is no escape from the cruelest of fates. The story-- only forty pages long-- is followed by essays and commentaries on Tolkien's work, and on the source material.
