Query: A GREAT book by RavenWolf

I am a long-time reader of various Witchcraft books. I have read RavenWolf's previous books and enjoyed them though a lot of people refer to her a "fluffy." Her new book "Solitary Witch" is an unbelieveable resource! It is one of the most impressive, researched books I have seen in a long time! HIGHLY reccomended!
