Which Tolkien story features Túrin Turambar as its central tragic hero?

The Children of Húrin features Túrin Turambar as its central tragic hero.

The story follows Túrin, son of Húrin, during the First Age of Tolkien’s legendarium. Morgoth, the chief enemy of that age, curses Húrin’s family after Húrin refuses to reveal the location of Gondolin. Túrin’s life is then marked by exile, warfare, mistaken identity, and the destructive effects of Morgoth’s curse.

Christopher Tolkien edited The Children of Húrin from his father’s manuscripts, and it was published as a standalone book in 2007. The narrative also appears in shorter or differently framed forms in The Silmarillion and Unfinished Tales. It is not the same story as Beren and Lúthien, though both belong to Tolkien’s First Age mythology and involve the broader conflict with Morgoth.
