Maggie finds herself in an adventure with eight Archangels (including Archangel Michael) who have asked her to help them clear the negative energies around a very old pilgrims' route on Dartmoor, called The Archangels' Way. They're on a mission to rid the Way of the impact of human history, smugglers, highwaymen, ghosts, pixies, energy centres, churches, ley-lines, death, peat bogs, gallows, haunted inns, rolling mists, stone circles, standing stones and holy wells.
It's a fascinating place with energy wormholes and crossing points between the dimensions giving Maggie and the Archangels plenty of disturbances to try to balance and of course Phineas, Archdemon and the Archangel of Chaos is there to make the task as difficult as possible.
