Query: 10 year-old loved it.

I purchased this book for my niece's 10th birthday. She loved it but had already received one just like it. She couldn't stop talking about how great it was and was looking at the list on the back of other books in the series that she could get in exchange for this. Perfect for the kid who is interested in science and the outdoors.
