Query: Fascinating history poorly presented

The history of the 1871 Polaris expedition to the North Pole and the mysterious death of it's leader Charles Francis Hall is poorly presented by this effort. It is well researched but the book would have benefitted greatly from an effort to edit and organize this presentation. If you are interested in the history of these events, a reader might look elsewhere for the information.
