In the late 1960s a new generation of young readers revived a readership in T. H. White's "The Once and Future King" (published in full 1958) and "The Lord of the Rings" (published in full 1956), and as a consequence Arthurian and heroic legends regained popularity among a critical mass of readers. Mary Stewart added to this climate by publishing "The Crystal Cave" (1970), the first in what was to become a four-book series later dubbed The Merlin Chronicles. The book placed Lady Stewart on the best-seller list many times throughout the 1970s and 1980s.
