I only got it for the Whiteleaf Cross background (and it was being chucked in for free with the Burl book)
most books with the word "Stonehenge" in the title are
a) nonsense and/or
b) not actually about Stonehenge
Stonehenge Landscapes is the best one. Hardly mentions the circle, all about the patterns of barrow placement and their intervisibility. Much better
