Tolkien, author of The Hobbit and The Lord of The Rings, died in 1973.
But fans will get the chance to read a new book by the author (well, new to them) this August.
HarperCollins will publish The Fall of Gondolin on Aug. 30, the publishing company announced Tuesday.
The book was edited by Tolkien's son Christopher, 93, and illustrated by Alan Lee.
The book tells of the founding of the Elven city of Gondolin, and is considered one of Tolkien's Lost Tales.
"We never dared to dream that we would see this published," said Shaun Gunner, chair of the Tolkien Society, on the group's webpage.
