This is a truly amazing book. I would highly recommend it to anyone who wants to explore their inner selves, spirituality, and personal healing. You don't have to be Wiccan, a Witch, or even Pagan to be inspired by this book. You would need to be open to these things, but I think any open-minded, spiritual person would enjoy it.
I think the book is in particular important for and aimed towards women and female-identifying individuals. It has a feminist base, and is really a journey toward empowerment. If you follow a Traditional Wiccan Path, the different paths in this book :Elements, Inner, Outer can be recognizable as similar to most teachings for First, Second, and Third Degree in many traditions, at least, the ones I am aware of. But, it doesn't matter if you have been a Witch for 2 weeks or 40 years or aren't at all, there is something in there for you.
Starhawk and Valentine are masters of imparting wisdom but not making the reader (at least, to my experience) feel like they are being talked down to or are dullards for not knowing what they know. You get the sense they are walking beside you and always learning new things too: a true mark of a High Priestess and Elder.
The book made me long for a sisterhood in person that I could practice these with, and to take part in one of their Witchcamps! However, while the group rites suggested were ideal, the solitary suggestions made everything customizable.
I could read this book 100 times and always find something new. Highly recommended!
