Query: EXCELLENT HISTORY ON THE U.S.

I've been a student of history for over 50 years and consider myself well versed in U.S. history. This publication is an excellent reference for the student and for adults. For the younger student (grades 10-12) it is an easy read, provides a concise yet brief of the major causes and effects of the evolution of the U.S. For adults it will refresh your understanding of our history and maybe brings other aspects of U.S. history that one may have forgotten or unaware of.I strongly recommended this book to those whom are interested in U.S. history and modern reflection between traditional and revisionist historians. Only issue that I have is that occasional chronological aspects are incorrect but does not detract of what the authors are trying to convey.
