Anyone who has studied pagan and wicca traditions for any length of time will ultimately find that they don't agree with everything they are taught. One of the joys of paganism is that you don't get hurled into a dark pit for such feelings but can make something positive of the experience and form or join a new tradition.
Many people have done this in the past (clearly, otherwise we would have only one Wicca tradition and a mere smattering of pagan ones), with various levels of success. Just like starting a new business, people often find that they are in over their heads and begin to respect their old teachers in a new light!
Enter Edain McCoy, and a book that is long overdue for publication. The Witch's Coven is exactly the book you need if you are thinking about starting your own tradition, coven or circle.
Although typically new covens and circles are started by 2nd or 3rd degree priests and priestesses that hive off from a mother coven, it is often the case that many people interested in Wicca don't have a local group they can join and find their only choice is to start their own. This book can help with that, since it provides pretty much all the information you need to get started, including:
How to find networking resources
What happens at initiation
How to create a coven or circle from scratch
How to screen potential members
Traps and Pitfalls to avoid.
There is much more in this very well written book and the author is clearly well-informed on the subject matter. The book is 200 pages, but doesn't seem it, and I've been going back over it trying to find something that was missed (the degree system? Nope, that's in there. Initiation rites? that's in there too), but the only thing I can say I would like to have seen would be a few more examples of how some rites and rituals may be done. The danger there of course is that they then get adopted by rote and before you know it we have the McCoy tradition, which I'm sure the author was trying to avoid...
All in all, I would say that if you are planning on starting a tradition, hiving off a coven or just forming a study circle, then this book would be the best place to start, but you will need to fill in the details yourself, which is as it should be!
