Having read The Old Straight Track, I never felt the need to know any more about Ley Lines, that is until I came across this book by Danny Sullivan. I thought it might show how things have developed since Alfred Watkin's book written 75 years previously. I was not disappointed. The author gives an update of the theories behind the straight lines, quoting in detail from a variety of sources. The book balances folk tales & customs, social history & ghost stories with scientific studies and astronomical research. Photos, diagrams, and an excellent Directory of 50 Ley Lines add to this detailed and thoroughly enjoyable read. I learned a lot. Thank You, Danny
