Query: I'm disappointed in the publisher...

I bought this book primarily because the publisher has in the past printed excellent-quality, informative books on space history, and I was expecting the same here.Instead, I bought a badly-edited, mean-spirited rant about space politics. Everyone's entitled to an opinion, but don't waste your money on paying for the ones in this book, especially as they are dishonest. The book claims to be an objective look at recent NASA policies, but is anything but. One administrator is portrayed as the devil himself, another as a knight on white charger, with no effort to truly make any objective analysis. A missed opportunity, and a misstep by an otherwise great publisher.
