An interview with me about the reissue of Dark Mirror and The Night Journey is up at the Centre for Pagan Studies blog.
You can pre-order the book from the Doreen Valiente Foundation online shop.
Me reading part of the chapter on the night journey, from The Night Journey: Witchcraft as Transformation.
2020 Update: the book is being republished in October by The Doreen Valiente Foundation in association with the Centre for Pagan Studies.
The article by Sabina Magliocco that I referenced is Who was Aradia?
