It is a detailed and technical book which discusses the finds in the cist from the bear pelt to the beads and the human remains etc. There is also a chapter on the landscape where the cairn was found which has been determined via pollen analysis. Some of the radiocarbon dating work for this is ongoing but the data appears to show that the area was a mix of bog and oak hazel woodland.
Will be delving more into this book over the Christmas period.
If you want a less technical book on the topic I can recommend this one
