The story was plotted 100 years ago by Lord Of The Rings author J.R.R. Tolkien - and finally it is being published.
Described as a "very personal story", Beren And Luthien is said by one Tolkien expert to be the author's way to tackle the horrors he experienced as a soldier in World War I.
The new book - about a love story between fugitive warrior Beren and Luthien - is edited by Tolkien's son Christopher, reported BBC News.
It boasts illustrations by Alan Lee who bagged an Oscar for his work on Peter Jackson's Lord Of The Rings film trilogy.
Tolkien died in 1973, aged 81.
