Philip Carr-Gomm has recently released a new paperback (with accompanying audiobook) called DruidCraft: The Magic of Wicca and Druidry. It highlights a particular path of Nature Spirituality that he calls DruidCraft. The author, the Chief of the Order of Bards, Ovates & Druids in England, describes how the two main avenues of Western Paganism–Wicca and Druidry– are both experiencing a renaissance and a coming together of sorts.
The book is available on Amazon; the audiobook on Audible and iTunes.
