Query: The first history book I have ever read in two sittings

This is the first history book that I have ever read in two sittings. I just could not put it down. I know people have varied tastes and expectations, and I respect this. But how anyone (not trying to be unkind) can give this book one or two stars bewilders me. Mr. Keegan's writing style is so lucid, so coherent, so easy to read and understand, so unpretentious that he took a subject that I knew very little about and made it come alive. He gave me an overall picture of the european political, civilian and military mindset of that era. I am a layman, maybe that is why I so thoroughly enjoyed and appreciated this book. If I had a PhD in history, maybe I would be more critical. For anyone who, like myself has (had) limited knowledge of the Great War. The war to end all wars, I highly recommend this book.
