Last of the anthologies. Robert Jordan's precursor to "New Spring" is in here, Ursula K. LeGuin contributes an Earthsea sequel, Tad Williams contributes a Memory Sorrow and Thorn prequel, and Terry Pratchett contributes a Discworld story about Granny Weatherwax. If you have a favorite series included, this is worth picking up.
Of the four authors, Le Guin was the only one whom I had read before. I thought the Jordan story was particularly good, and really liked the ending. The star of the book was the Tad Williams story, which I thought had great character development.
