I liked the reading a lot.
The story itself was a lot of fun, and pleasant enough to listen to, but I guess I actually prefer a more flawed story (like 14 Postal Experiments, or Hotel Astarte) that gives me more to think about even as I'm complaining about it.
This one didn't give me much to complain about (aside from a little bit of triteness in the "I'm gonna steal your man" storyline), but it also didn't leave me with much of anything else either. Pleasant, funny, cute, well formed characters. I doubt I'll be able to remember what it was about in a year.
Also, and this is more personal, "Magic Bird Eggs" is also a plot device in the Disney Fairies books that I read to my girls for bedtime stories (See, e.g., "Fairy Dust and the Quest for the Egg"), so the Sparrow Egg part just made me think of "Mother Dove" from the Disney stories.
