The Town of Hercules - A Buried Treasure Trove by Joseph Jay Deiss (nonfiction 1995)

While this book is geared towards people who don't know much about the Romans, the best part is when the author describes the city of Herculaneum itself.  There are not enough color pictures.  The relationship between the Getty Villa and the Villa of the Papyri is explored extensively, as the book is published by the Getty Press.  There's no mention of any of the more controversial aspects of the Getty Foundation's relationship with art thieves, of course.
