Unfinished Tales - J. R. R. Tolkien

J. R. R. Tolkien's Unfinished Tales is a collection ranging from the time of The Silmarillion – the Elder days of Middle-earth – to the end of the War of the Ring in The Lord of the Rings. Its many treasures include Gandalf's lively account of how he came to send the Dwarves to the celebrated party at Bag-End, the emergence of the sea-god Ulmo before the eyes of Tuor on the coast of Beleriand, and a description of the military organisation of the Riders of Rohan.
