Query: Stephen Ambrose?

I read this book a couple of years ago. While the overall story was interesting I remember being very unimpressed by the writing style.I just pulled the book out again and went through a couple of chapters. Sorry to say but the quality of writing is very simple and not nearly up to the standard of Ambrose's other books.I'm wondering if he really wrote it - or had it subcontracted out.
