Which Tolkien work was published posthumously in 2007 as an expanded standalone tale of Túrin Turambar?

The Children of Húrin was published posthumously in 2007 as an expanded standalone tale of Túrin Turambar.

Christopher Tolkien edited the book from J.R.R. Tolkien’s writings, combining material from The Silmarillion, Unfinished Tales, and other drafts. The story follows Túrin and his sister Niënor during the First Age, when Morgoth’s curse brings tragedy to their family.

The 2007 volume is not a newly written novel from J.R.R. Tolkien’s final years. It is an editorial reconstruction based on texts created at different times and in different forms. Christopher Tolkien supplied an introduction, maps, and explanatory material to help present the narrative coherently.

The tale is among Tolkien’s darkest major stories and is closely connected with the wider mythology of Beleriand. It differs from Beren and Lúthien and The Fall of Gondolin, which were also published in later standalone editions but focus on different First Age legends.
