This is a very interesting book. I fully recommend it to anyone looking for spiritual answers. You may not agree with everything -- and that's OK. But take whatever you get from this book and simply make it yours.

This really is a great place to start if you want to know more, but really don't know where to go to find the answers to your questions. However I wish it spent more time focusing on Wicca instead of leaping into magic and witchcraft as it does not define strongly enough the necessity of the former to the latter. This book presents information in a way that is easy to read and begin to get an understanding with, though it really seems like the Cliff's Notes version of Scott Cunningham's Wicca, which I would highly recommend to read second (or alongside) in order to fill in some gaps, un-generalize some subjects, and continue down your path with.
