This was a really cute book, quick and easy to read, and longer than I expected it to be (which is a good thing). Even though it essentially boiled down to a series of Aesops, it never did fall into the trap of heavy-handed moralizing that Aesops often do, and the lessons it taught were well couched within the plot. The characters were all very likeable, each with fun little quirks, and the humor alternated between subtle and sweetly corny.
There were a few places in which the plot slowed quite a bit, during which Andy was exploring, or the narrator was explaining something, and I think those expository passages could have been integrated much more smoothly. I also felt that the ending was much too abrupt, though it did come with a good amount of closure. Additionally, there were a number of small typos and incorrect word usage, but not nearly as many as one sometimes sees in a self-published book.
Overall, I enjoyed the read. It's something I would certainly consider giving any hypothetical future children of mine.
