Don't recommend.
Format: Paperback, Format: Paperback
Not at all what I was expecting. It must have been self or independently published. Returned. I will definitely be scrutinizing my next book purchase on this subject to more stringently. Also, Not that I care but claiming to be "7 books in one" is a false claim. But I kind of figured that before I purchased it. Its just bad. Big turn offs for me. -No/poor editing. -Page formatting makes my eyes bleed. -The font tries too hard to be fun--especially for an instructional book. -pages feel cheap. -image quality is abysmal. - none of the information I was looking for and lots of information I wasnt.

Not helpful
Format: Paperback
This book is so basic it doesn't really help much in tips on identifying rocks and minerals. The photos are enlarged so much they are distorted and most photos are of the rocks cleaned and polished. That doesn't help with how to spot things in nature or where to look. I'm really disappointed. Also, Montana has a lot of cool rocks but all books ever speak of are sapphires and agates. I feel like I wasted my money. There are some helpful things but even as a beginner, most of the contents are known.
