The book covers a lot of good information, but it is poorly written and not laid out well. The first chapter rambles on for pages at a time about physical features on the moon and never shows a picture or map of where the feature is. For the current price (under $10) its not a total loss, but this is the second Firefly book I have read and they were both pretty bad.Bottom Line: Bad book - Buy Exploring the Moon by Steve Massey instead.
