Query: The Best Fantasy.

The first time, I read these three books over a weekend--of course that is all I did. These first three books of Thomas Covenant, Lord Foul's Bane, The Illearth War and Power That Preserves remain for me the measure by which all other fantasy is measured (including the later books of Mr. Donaldson.) In 1979 when I asked the author how he had tied up all the characters and plots to produce an ending so worthwhile, he said he wrote the book backward from the ending to the beginning. Thomas Covenant is not an inviting character all the more amazing then is his transformation. The first 50 pages are difficult, but wonders await. After 30 years I am reading them the third time. Donaldson's imagination is staggering. His use of the English language wondrous. Please endure the beginning, the ending is well worth difficulty in the beginning.
