Somebody on Goodreads made a comment about how this book demonstrates that there is nothing that humanity has created that has not already been developed by the animal kingdom. I would probably say that this is pushing it a bit too far because the animal kingdom has yet to develop the ability to fly...
Warm and fun, this tale of a time-traveling girl and the adventures she has in the past is set off brilliantly by the author's wry presence as a character. Delightful.
