I was engrossed very quickly...I found the whole water-Witch tradition fascinating Touchstone The Trent boat families, or Fryske as they sometimes call themselves, had a private Pagan religion of their own with a long pedigree. It was and is concerned with the earth and, not surprisingly, water. Extended families were matriarchal and met once a month on the new moon. Water Witches describes the way of life and religion of the Pagan Fryske.
