This substantial tome is "an in-depth look at the history, the land, the wineries and the wines of Napa Valley." Coming in at 13 pounds and 1255 pages, it is hard to imagine anything more "in-depth" than this book. The only condition issues are significant rubbing on the back cover and a small (1/2") black ink mark about halfway through the book on the very bottom of the page edges. If you are interested in California wines, this book will keep you busy for a very long time!
