Query: Amateur book, too expensive

I bought it, read it, and do not recommend it. It is very "amateur" in that the book seems to totally misunderstand almost every topic it sets out to attack. Besides, it provides basically nothing new or insigtful. The price is way too high for such a thin glossy hardcover book.Sigh... besides some obvious errors , most of the derivations (MM, BS, Supply-Demand,...) are either incorrect or superficial or naiive. No real insight is provided; conceptually messed up; the title is big but has little to do with the content; some discussions are fair but some are just laughably ignorant; overall --- somewhat disappointing. I would not give a 1-star rating if the price were below $10 as most little paperback books are.
