This is a good chronological summary of the events and battles of the Civil War along with a biographical summary. The book is just a series of facts and not meant to be told as a novelistic story but very detailed and well done.
As a single volume book on the war, it's pretty good, although people who have read many Civil War books (like me) most likely won't learn anything new about the war. Personally I thought the sections on weapons and naval warfare were the best, since I haven't done much reading in these areas. The chronology section was nice, since readers can see what's happening across the country on the same day. It does have several minor mistakes, however; for example it refers to Joseph Hooker as "John Hooker" a few times.
