This book is not bad at all! I bought it for my 13 year old daughter interested in paleontology, to learn all kinds of rocks and I find it very well. Many pictures, all rocks are categorized, even for a first approach to an adult why not? Then we can deepen by buying books much more precise, the -C is rather an overview .This decided me to buy this book is the fact that one can leaf through, too many books on the rocks do not have this option, it is a pity.
