Maia Toll has been many things -- including a horseback riding instructor, a clinical herbalist, and a university teacher -- but being an author is by far her favorite. Her Wild Wisdom series, featuring bestseller The Illustrated Herbiary, The Illustrated Bestiary, and The Illustrated Crystallary, offers a glimpse into the knowings of the natural world and the wilds within ourselves -- insights Toll contemplated during her yearlong apprenticeship to a traditional healer in Ireland. When not reading books and "talking" to trees, stones, and her two dogs, she helps to run Herbiary, a multi-city natural wellness and sacred living store she owns with her partner, Andrew. She teaches and blogs to an international following at maiatoll.com.
