American Creation: Triumphs and Tragedies at the Founding of the Republic by Joseph J. Ellis
I just checked this out of the Joshua Hyde Library in Sturbridge.
I am only up to the part where Washington and his troops leave Valley Forge for the spring campaign. I am finding the book to be very enlightening.
I have now finished the book and am even more impressed with the lessons to be learned. Follow the link in the original posting to my book web page that has the details.
