JRR Tolkien book Beren and Lúthien published after 100 years

The story is about the fate of lovers Beren and Lúthien, a mortal man and an immortal elf who together try to steal from the greatest of all evil beings, Melkor.

For the new book Christopher Tolkien, now aged 92, has kept his father's story in the original form in which it was written and has also shown how the narrative changed to become part of The Silmarillion.
