The book begins with five general chapters but is mostly taken up with a gazetteer of 126 cemeteries with an essay on their location, acreage, history, topography and noteworthy monuments. In this it is authoritative and readable. It also contains 200+ photographs (in black and white). Unexpectedly for a book of this type there are many laugh-out-loud moments, resulting from the sharp descriptions of some of the lowlights (the 3-paragraph demolition job on Trent Park is a hoot).
By contrast, the lists of `residents' is routinely dull, over-populated with Victorian worthies who hardly count as famous these days. (And the lists are of people, not monuments, as unmarked grave-dwellers are included.) It is not obvious that these lists have been updated much since the first edition 20 years ago. Revising with more recent occupants would easily make this a 5 star publication. Grave locations within the cemeteries are not given, but this may be too big an ask.
Overall strongly recommended, but perhaps best read in conjunction with the findagrave.com website to identify more contemporary - and interesting - residents.
