On the plus side, Agnes never took credit for any of the healings or miracles, instead crediting God. I thought the part about Agnes killing a boy when she was a child was too sudden and ultimately brushed over, making it pretty implausible. Also, I had a hard time getting past the stereotypical negative attributes the writer assigns to and repeatedly reinforces about Agnes. Some things you'd just rather not think about or envision, let alone be reminded of them repeatedly.
This is four part series. Part two is much better (and not that related to this first volume).
