I read this book with my Shelfari horror group. I enjoyed it!
Knock Knock is the story of three young girls that brought something to life. Something that will follow them for the rest of their days.
I thought this a well written story with good character development. I got to know the three women rather well over the course of their lives, and I enjoyed that.The pacing was okay- there were a couple of portions that dragged a little bit, but the ending more than made up for the slow spots.
I enjoy not being able to predict the ending of a book and this one ended in a surprising way. Overall, I really enjoyed this novel. Recommended for fans of supernatural horror!
