Nobody does odd retelling like McKillip and this one was definitely odd. But fun and compelling and weirdly funny. The incongruities between Arthurian legend and modern technology were handled perfectly and going back to rediscover all the places and hints McKillip dropped in is surprisingly fun. The story felt a bit odd until I worked out the Arthurian bits, so I'm not sure how much it rewards the unfamiliar reader, but I enjoyed it a lot. Its sense of humor reminded me of Riddlemaster of Hed.
