What is the author's style in The Hot Zone by Richard Preston?

The majority of The Hot Zone is written from the third-person omniscient point of view. Of course, the author is not simply composing characters' thoughts and emotions. This book recounts a true story, and Richard Preston interviewed many, many people to learn directly from those involved. Therefore, the reason the author is able to be omniscient is because he has taken great pains to be accurate in his telling of the tale. If he describes someone's internal reaction to an event, he is relating what that person told him. He is also careful to give credence to everyone's viewpoints in the cases where people have differing recollections of a sequence of events.
