Query: Damn boring book

I never found a book which can be bored then this (I am talking about all of the books of this series). When you start reading from the first page until the end of any particular paragraph, you will find that you have no idea on the topic other than some point form summaries. You are only suggested to purchase this Wiley CIA series unless you do not have other choice. If I can give zero rating, I will surely do that. Never can imagine that it costs USD150 with such bad content as well as bad paper quality.
