I really enjoyed this book, especially the original-ness of the plot. When the father of the Barrett family loses his job, they are not in the best place financially to support their mentally unstable daughter. Is it a newfound faith in God that makes the father decide to side with his priest, or the chance to make some much-needed money? Either way, Mr. Barrett agrees to allow their family to become the center of a new documentary titled "The Possession". Is their daughter actually possessed, or mentally unstable? When told through the eyes of the youngest daughter, who is only 8, it's hard to tell who is the true maniac of the family.
