Query: Fascinating Pre-History

One of the sites I plan to visit on an upcoming trip to England is Stonehenge. When I went looking for information on Amazon, I came across this novel. I found the story line compelling enough to keep me caring about the characters and turning the pages. I particularly liked the author's educated guesses about how, when, and why this stone circle was built. I think it will make my visit to Stonehenge more enjoyable.
