I've recently become aware of the writing of Glennie Kindred, whose website is here. In an article from her website, Glennie describes herself thus:
I write and illustrated books on Earth wisdom, Earth cycles, Celtic festivals, trees, herbs, hedgerow gathering and cookery, creating our own ceremonies and alchemy. I am interested in taking old knowledge and creatively applying it to our lives today. I believe that as we heal ourselves and our relationship to the Earth, we add to the healing of our world.
I recently bought her wonderful book The Earth's Cycle of Celebration and have just ordered Creating Ceremony from Glennie's website. The books are hand-lettered and -illustrated, and have a great beauty and love about them.
