id recommend cheryls books!, in the time i lived in cornwall they were a great help, and so was she, i did contact her on occasion and proved extremely helpful.read the book 'fogou' a while back after i had visited the fogou , meditation in there was very interesting, indeed a very powerful place, it is or was a site used by locals for ritual, i know this through freindship with such a person in the past, but dont let that put you off visiting so bear that in mind if you do get a chance to visit.But id certainly recommend a visit to Haliggey fogou(think its spelt as such), again an extremeley powerful site, very dark!!!!, a must to visit.thing is when you come to cornwall youll find most of the small newsagents stock some very good books on the local sites,its where i found quite a few, youll also find a lot of material in the local 'spiritual' shops down there, 'Healing Star' in Penzance is a very good place to go, very freindly people who i found good friends!.

good luck
