Which Tolkien work was published posthumously in 2007 as a standalone story about Túrin Turambar?

The Children of Húrin was published posthumously in 2007 as a standalone story about Túrin Turambar.

Christopher Tolkien edited The Children of Húrin from J.R.R. Tolkien’s longer and shorter versions of the tale. HarperCollins published the completed standalone edition in 2007, with illustrations by Alan Lee. The story belongs to the First Age and is one of the major tragedies of Tolkien’s mythology.

Túrin is the son of Húrin, a human warrior who is cursed through the actions of Morgoth. The narrative follows Túrin through exile, warfare, mistaken identity, and disastrous choices. Its tone and structure differ markedly from the lighter adventure of The Hobbit.

The story had appeared in earlier forms and partial treatments, including material in The Silmarillion and Unfinished Tales. The 2007 edition was significant because it presented a continuous narrative rather than leaving readers to reconstruct Túrin’s story from separate passages.
