AUTHOR Nigel Twinn will be signing copies of his latest work at Bookstop in Tavistock on Friday, November 9, between 10am and 4pm.

Beyond the Far Horizon describes the life and work of Billy Gawn, the UK's most experienced earth energy dowser alive today.

As well as describing Billy's fascinating discoveries in the fields of water divining, archaeology and emerging science, the book gets as close as anyone has come so far in answering the age-old question — why does dowsing actually work?
