OakRaven's short 5-star review summed up everything I was going to say about this book... although I really want to emphasize that this book picks up where Green Witchcraft left off.
Where GW is the perfect guide for beginners, those looking to move beyond the more "static" ceremonies of that book will absolutely want to graduate to this one (and I do mean graduate, since this book is, in my opinion, what GW II & III should have been). Where Moura's books lay out set instructions for going from Point A to Point B, Palin assumes that you have the basics under your belt, and sets you free to roam and explore literally everything out there.
When I got into this stuff five years ago, I didn't have any idea how real it was... but now that I do, this is the single most important book I own. Buy this if you're looking to take that next step!
This is a fantastic book and a wonderful resource for anyone seeking a deeper connection to the natural world through magick, humility and the tides of nature. In addition to Aoumiel's Green Witchcraft series, I recommend this book to the Earth-based spiritual seeker. May it serve you well (and it will)! :-)
