_The Wiccan Path_ consists of a series of letters written by Rae to two of her students, Tessa and Glyn, as she guides them through their Craft education. Halfway through the book, Glyn "drops out" when he marries a non-pagan, and the rest of the letters are written only to Tessa. Within this framework, Beth explains the Craft, as one other reviewer put it, as if you were learning it over tea at someone's table. This is how I imagine it would feel to be taught by your grandmother in a family tradition, something most witches aren't fortunate enough to experience.
Beth's correspondence includes a letter about each Sabbat, explaining how she celebrates and giving her students ideas for adapting the traditions to suit their own needs. Each of these chapters includes a full ritual, and unlike some of the more "formal" Wicca 101 books, the rituals are presented in an open-ended manner. They are merely suggestions, not prescribed lists of archaic-sounding incantations to be said in a specific order. They're just Beth's ideas, and she presents them as such.
Other subjects she deals with are trance-work and the deities. Her letters on trance-work are wonderful, and gave me tons of ideas. In her writings about the deities, she is as open-ended as she is about everything else, not giving them specific names, but leaving that up to the preference of the practitioner.
If you're looking for a book of formal rituals and formulaic spells, this isn't the book for you. If you want to learn the Craft the way your grandmother would have taught it, pull up a blanket, grab a cup of hot chocolate, and settle into a comfy chair with _The Wiccan Path_.
