Haven Woods is suburban heaven, a great place to raise a family. The crime rate is practically non-existent, unless you count the odd human sacrifice, dismemberment, demon rape and blood atonement. When Paula Whittmore goes home to Haven Woods to care for a suddenly ailing mother, she brings her daughter and a pile of emotional baggage. She also brings the last chance for twelve of her mother's closest frenemies, who like to keep their numbers at thirteen.
