If I remember correctly, Dorothy Morrison is an elder of the
Georgian Tradition, which is an Initiatory Witchcraft Trad. My understanding is that it is fairly similar to Trad Wicca, however it is missing the core mysteries and cannot trace lineage to Gardner or the New Forest Coven.
As far as I know, her books are fairly decent, as long as one realizes that they aren't really about Wicca.
