Query: Not the best

I have studied Titanic for many years, starting way before James Cameron's film. Many of the "facts" presented in this work go against those given by tons of other authors and explorers of Titanic. The author seems very full of himself, trying to give himself credit where he doesn't deserve it. It almost seems as if he is trying to convince everyone that he was a co-discoverer of Titanic and Robert Ballard's best friend. I would recommend another author, one who actually has a love for Titanic and isn't trying to make himself look better.
