Query: Author was very ill-informed

It was obvious from the first couple of sentences, that the author wasn't on top of things when it came to reporting about Mariah. His first mistake was getting a simple fact like her BIRTHDAY wrong! I was left sceptical about how much he actually researched for the book. As a MAJOR MAJOR fan of hers, this really irked me. I was hoping to find out something about my mentor that I didn't have access to learning. No such luck. Most of the book was a repeat of articles written on her by other journalists.The book was very positive for Mariah. The few photos that were included were beautiful!For those that don't know much about Mariah, I would say this is a good book to start out with, but do something the author didn't do...research what is being said. Read another book on her, go find another article on her, you'll find that some links were missed.
