What is the author's tone in the nonfiction book, The Heavens and the Earth?

The book is written in an objective and factual tone. It is historical in nature and therefore is presented chronologically for the most part. This makes it easy to follow for the reader, who doesn't have to do any backtracking. There are a lot of names mentioned and it is somewhat of a challenge to pick out the important ones. The third person style of writing adds to the objectivity of the book.
