Query: A Modern Horror Novel

I read this book as a straight-up horror novel. It doesn't work any other way. If you take it on as serious social commentary, an examination of school shooters, serial killers, nature vs. nurture, marriage and parenthood, the book turns silly and repellent. Approaching it as a horror novel featuring one of my favorite plot devices -- the unreliable narrator -- allowed me to truly inhabit Eva's point of view and to relish the tale's shocking (and campy) ending.
