I started reading this as a sort of throw-back to my 6th grade reading habits, when I discovered folk tales. Irish folktales are often classified as ghost stories, which I generally avoid, but I enjoyed them anyway.
I thought the tone of the first part was rather interesting-- it's a non-fiction setup, but stories about ghosts and wraiths tend to read as fiction. Not to knock non-fiction, but it also tends to be more dry, so I enjoyed the ghosts and wraiths a lot: they're interesting, and it is something to consider. I personally don't feel I can say whether or not such things exist, although I admit it seems far-fetched to me. Nonetheless, what would it be like to be part of a tradition or culture that really believes that the dead and buried actively participate? What would it be like to see them? I feel that Haunted and Bewitched Ireland narrated the stories in such a way that those questions were ranged.
The second part of the book was comparatively dry: it focused on historical figures and witch trials. Interesting topic, but rather appalling at times. On the whole, though, it was great. I'm interested in doing some more research on witch trials and their history now.
