I bought this book without looking at the number of pages. When I received it, I couldn't believe how thin it was. This book is 94 pages of bold print. What a joke. It is an overview at best without going into any details that would be useful to a greenpea. In my opinion, a complete waste of money. Should have been no more than three or four bucks.
