The Children of Hurin written by J.R.R. Tolkien and edited into shape by his son Christopher, will be released by HarperCollins. This expands upon an earlier version told in The Silmarillion.
The story is set long before "The Lord of the Rings" in a part of Middle-earth that was drowned before Hobbits ever appeared, and tells the tragic tale of Turin and his sister Nienor who are cursed by Morgoth, the first Dark Lord.
