Query: My husband cannot put it down.

I purchased this product for my husband for Christmas. He is thrilled with the book. He had an uncle who was a part of the Merrill's Marauder Rangers, and he has a hard time putting it down when he starts reading it. I looked at a number of books containing information about Merrill's Mauders, but this one seemed to be the only one I found exclusively about them.
