Query: Valley of the Shadow of Death

This book was mind numbing. I believe historical books are supposed to have facts and information that is easy enough to comprehend. All that this book provided was the ramblings of colloquial dialog. This should be a book on tape not a book of historical text. The Valley of Shadows was to be a source of information for a conference on Lincoln's Antebellum America, I wonder how many of my colleagues did as I did with this work, SKIM.
