Just been given this by a friends as a very late birthday pressie. He picked it up secondhand at a music festival. Have put a short review on the Leskernick site.

Not had much chance to look in to book at depth but some interesting theories in it...and it also brings up again the question of 'what is a natural stone and what is a placed stone'
