Query: Incredible fantasy for all ages

This one was a gem. I admired everything about it: the simple storytelling, a richly created atmosphere, the symbolism, and the darker implications. Momo is truly a wonderful and memorable character, I especially liked the chapter when she plays make-believe with her friends. The things that the men in gray represent are very obvious and this made them all the more frightening. I was a little uneasy about the way the novel sometimes switched between old fashioned fantasy and modern reality, but suppose this was just to drive the implications closer to home. All in all, this was excellent, I highly recommend it.
