More Amazing Book Covers

From left to right, great books with memorable cover art. The second image is taken from Lloyd Alexander's The Book of Three, with artwork by Jean-Leon Huens. Rowena Quadflieg provides the art for The Neverending Story. Unfortunately, I've yet to find the name of the artist for the above edition of A Swiftly Tilting Planet (this is the version of the cover that I remember the most from my childhood in the early 1980s).
