Quick recap
The book gathers the versions of this story Tolkien wrote over decades, in prose and verse, with commentary by Christopher Tolkien. The mortal Beren enters the Elven realm of Doriath and falls for Lúthien. Her father, King Thingol, names his price: a Silmaril from Morgoth's crown. With help from the hound Huan, Lúthien frees Beren from Sauron's dungeons, and the two sneak into Angband in disguise, where her song puts Morgoth to sleep. Beren cuts a Silmaril from the crown, but the wolf Carcharoth bites off his hand. Beren dies hunting the wolf. Lúthien dies of grief, moves Mandos, and the two return to life as mortals.
