A very simplistic pagan primer. It's the who, what, when, where, and why on modern Paganism/Neo-Paganism. However, in places it's rather stripped down and over-simplified.
This book is perfect though for giving to curious Non-Pagan family and friends who are concerned or wondering about your spiritual path/religion. It is a good non-frightening introduction.
However, if you are someone who is a pagan, or looking towards paganism possibly being your personal path I highly recommend Paganism: A Guide to Earth-Centered Religions by Joyce and River Higginbotham.
All in all, O'Hara's book is a good volume to have in the library and to have read for sharing with the curious family and friends.
