This book was really fun to listen to and my rating is reflected as an adult reader (five stars for a child or teen). The story line is cute (nothing deep) but the lack of depth is made up for by scientic facts! Even though this was meant for someone younger, I found myself learning many things (all facinating facts). Want to brush up on your planetary knowledge? This book is a perfect, quick, fun read that I would recommend to ANY parent. Buy the audio book and play this in the car to the kids and I bet they'll want more! Apparently this is the second book to this series and although I found that out halfway through listening to it, this didn't bother me at all. I would have enjoyed starting off with the first book though, and would recommend others to do the same.
