Lionrhod at tweentheshadows.com has an entertaining list of Pagan/Magick books to avoid:

"Every now and again, you're faced with the violent urge to take the book you're reading and throw it against the wall as hard as you can. To watch the spine break and the pages flap around like wounded birds. Now I don't get that way often. I'm a voracious reader with a vast reverence for my books. And a writer with a great number of works started, but not as many as I'd wish completed, I salute anyone who gets to the point of mailing something out to a publisher. But here and there I'll be asked if I recommend a certain book and will have to answer with a horrified, "No WAY!"
