Gemma is a practitioner, writer and craftsperson of folk magical tradition. Her particular areas of interest are in the employment of signs, substances, loci and physical charms within the folk-ceremonial traditions, the cunning-arts and traditional witchcraft, with a particular focus upon the South-West of England where she lives and works.

Gemma’s first book; Traditional Witchcraft – A Cornish Book of Ways, is a personal expression of modern traditional witchcraft in Cornwall, drawing upon traditional Cornish magical heritage. The Black Toad, Gemma’s second book for Troy Books, is an exploration of traditional magical practices of the West Country, with a particular focus upon Devon and Cornwall. Gemma is currently working on a number of other book projects, for Troy Books and other publishers. Gemma is also an illustrator of her own and other authors' books.

The careful crafting of traditional magical charms, as well as tools and working artefacts of the Art Magical are other important aspects of her work.
