Query: Don't judge a book by it's description!

I should have read a few more reviews before I purchased this book-- I recently started developing Crystal Reports from our CRM system and thought this book would help me get started quickly. I found that after about an hour it was useless and some parts concerning the web architecture were just plain wrong.I don't understand how this title could have got so many good reviews-- Since a number of them mention the author's services, she must be using them to plug her business.Take it from someone who would like to get a refund--leave it on the shelf.
