The Silmarillion by J. R. R. Tolkien

Set primarily in the First Age of Middle-earth, The Silmarillion contains the legend of the creation of the world and an account of the Elder Days. It is the ancient drama remembered by Elrond and Galadriel in The Lord of the Rings, and the harrowing origin of the adventure that ends ages later with Frodo and the One Ring.
