Unfinished Tales is a collection of narratives ranging in time from the Elder Days of Middle-earth to the end of the War of the Ring, which further relates the events as told in The Silmarillion and The Lord of the Rings.

The book concentrates on the lands of Middle-earth and comprises such elements as Gandalf's lively account of how it was that 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, an exact description of the military organization of the Riders of Rohan, and the journey of the Black Riders during the hunt for the Ring.

Unfinished Tales also contains the only surviving story about the long ages of Númenor before its downfall, and all that is known about the Five Wizards, the Palantíri and the legend of Amroth.

This is probably the last of the Tolkien volumes I'll read, and it seems from the description that it will enrich and give background to the stories I already love.
