AnonymousJohn Michael Greer is an interesting writer who has a regular blog at http://www.ecosophia.org He has written many books including science fiction and horror fiction. He runs his own Druid order in America the AODA. From what I have seen his paganism appears to take a more ritual, ceremonial magical approach and the books which he has written on Druidry appear to be like this. His Druidry Handbook is quite useful.
