This book does not offer anything in the way of even decent maps. It is tough to follow along with the text when you have no decent maps to look at. I have numerous other books on the Petersburg Campaign, and I found myself referring to the maps in these books repeatedly. The book does offer a coherent, concise analysis of the campaign in one book, which is an extremely valuable thing. You had better have other resources to look at while you read, though, or you won't pull anything useful from this book, aside perhaps from some information from the numerous excellent sidebars.
