Query: This is an EXCELLENT book!

This book has been an excellent source for beginning my knowledge about the occult. I have learned very valuable information and am elated to have had the opportunity to own a copy of this great publication. I am sharing what I have learned with people who are unaware of the "spiritual" dangers that can result from celebrating Halloween; a holiday that most participants would like to believe is innocent. Congratulations and much thanks to authors Mr. Phil Phillips and Ms. Joan Robie for a work well done!
