I just read in The Atlantic that Tolkien is publishing another book. It's about Hurin's children (Turin Turambar and Nienor, I assume). Kind of surprising. The Silmarillion already contains a lot of detail about Turin. No matter. I'm looking forward to it.
"Like the Lord of the Rings films, J. R. R. Tolkien’s canon is taking its time in drawing to a close. [On April 17th], the late author’s Children of Húrin goes on sale. Set long before Lord and imbued with a more tragic tone, the tale was pieced together by Tolkien’s son, Christopher, from notes and fragments."
