The author comprehensively covers the archaeological wonders of Orkney, going in a chronological fashion, and also brings Orkney history up to date and covers the designation of some sites as World Heritage sites, and also various digs and the impact of the designation. While the best-known sites are Neolithic, like Skara Brae and the Ring of Brodgar, the author also talks about the earlier Mesolithic, the Bronze and Iron ages, and more recent historical artifacts and finds. The book is lavishly illustrated with glorious photos of the sites, most of them multiple times, but could have used more maps.
I read this prior to a visit to Orkney, and found it enlightening and interesting, though confusing as well; I had trouble sorting out the organization as I was reading, and several sites were covered twice, sometimes with the same information, which makes me think the book was not designed to be read straight through. The text is not scholarly and is very readable, though I often felt overwhelmed with place names and the names of towns/archaeologists/etc. I would rather have heard more about just the types of sites, and leave out the flood of place names unless one place, like the Brodgar Peninsula, is particularly significant. Overall, though, an informative read.
