Which Tolkien novel was published in 2007 after being edited by Christopher Tolkien?

The Children of Húrin was published in 2007 after Christopher Tolkien edited J.R.R. Tolkien’s writings.

The novel presents the tragedy of Túrin Turambar and his sister Niënor during the First Age of Middle-earth. Its central conflict is shaped by the curse placed on their father, Húrin, after he refuses to reveal information to Morgoth. The story is one of Tolkien’s deepest explorations of fate, pride, war, and family suffering.

J.R.R. Tolkien had written multiple versions of the tale in different forms and at different stages of his career. Christopher Tolkien assembled a continuous narrative from those materials, using passages from completed prose, drafts, and related texts. The result was published in 2007 with illustrations by Alan Lee.

This book is not the same work as The Silmarillion, although both draw on First Age material. The Children of Húrin gives one legend a fuller novel-length treatment.
