Daughters of the Witching Hill

Well, it's only book 4 for the year, but the best one I've read so far this year.
The story follows 3 generations of so called witches back in teh late 1500's, early 1600's in England. The story starts off from the grandmothers point of view and her experiences with a guiding spirit. The rest of the story is then told from the granddaughters point of view from the time she is old enough to have memories. The story pulls you in and gets really good towards the end when the women are tricked into confessing they are witches. It will leave you hanging on to each word wondering what is going to happen.
I read the Afterword and the story is actually based on true events, although ficticious characters and events were added to the story.
