What is the author's style in Lindbergh by A. Scott Berg?

Berg lets the story tell itself, with only the slightest indication of how he feels about the events he is describing. Berg fills in even the smallest details because of his exhaustive research on the subject. He can speak of any particular situation from Lindbergh's life from different perspectives because he has dug up the memoirs, letters, and public statements of other participants. He knows his subject thoroughly and so is able to give each moment in his book a feel of truth without having to draw attention to the facts, which he presents to speak for themselves.
