What is the title of J.R.R. Tolkien’s 2017 book about the mortal Beren and the Elf Lúthien?

J.R.R. Tolkien’s 2017 book about the mortal Beren and the Elf Lúthien is titled Beren and Lúthien.

The book was edited by Christopher Tolkien and published posthumously in 2017, with illustrations by Alan Lee. It brings together versions of one of Tolkien’s central love stories, in which the mortal man Beren and the immortal Elf Lúthien undertake a perilous quest against Morgoth.

Rather than presenting a single newly written novel, the volume traces the story through poems, prose narratives, and later revisions. Christopher Tolkien explains how the tale changed across his father’s career, allowing readers to see Tolkien’s creative process as well as the final form of the legend.

Beren and Lúthien has a special place in Tolkien’s mythology and biography. Tolkien and his wife, Edith, are remembered in connection with the story, but the book itself is distinct from The Children of Húrin and from The Lay of Leithian, an earlier poetic treatment of the same legendary material.
