Hello, I noticed two authors who have been recommended that gave me pause. You might want to do a little research on Edain McCoy before you buy (or believe) any of her books due to execrable facts and laughable history, and Sean Belachta - he has a very questionable reputation in the Craft community. I urge you to Google these authors and make up your mind.
However, I'd like to add a book I haven't seen listed here - The Elements of Ritual by Deborah Lipp. A very fine book for those who lean toward Trad Wicca.
