In this book, Christopher Tolkien has attempted to extract the story of Beren and Lúthien from the comprehensive work in which it was embedded. But that story was itself changing as it developed new associations within the larger history. To show something of the process whereby this legend of Middle-earth evolved over the years, he has told the story in his father's own words by giving, first, its original form, and then passages in prose and verse from later texts that illustrate the narrative as it changed. Presented together for the first time, they reveal aspects of the story, both in event and in narrative immediacy, that were afterwards lost.
