McCarthy's thesis is clear. In his introduction he states "Fairy tales are among our most formative influences, adding a visceral heft and sting to the purely verbal warnings of authority. But fairy tales, without exception, hinge on a supernatural occurrence. And in a way, this seemed to undermine their authority, to relegate them to some other universe where things like that could really happen."And so he takes the fairy tale and thrusts it into the heart of science fiction. You might recognise some of the stories, while others are new or are retellings of stories hidden in the margins of Grimm or Perreault. With stories based on "The Emperor's New Clothes", "The Sleeping Beauty", among others, there's a mix that ranges from the hardest of hard SF to stories that skirt the edge of fantasy - and very little in the way of weak material. Yes, there are stories you might not enjoy, but they all maintain a high standard of technical excellence
With a roster of writers including Gregory Benford (whose retelling of "Goldilocks" is a wonderful work) and Paul di Fillipo, this is one anthology worth adding to your collection, alog with Peter Crowther's Mars Probes and Moon Shots. Enjoy.
