Brendan and Sherilyn. A young couple in love. Each has met their soul mate, and nothing can come between them. In fact, the Gutteridges are so wrapped up in each other that their neighbours barely know them, despite the woman next door’s nosy curiosity. Their families and their work colleagues see only the perfect couple in the perfect home, the perfect car crouching in the drive. And then a baby is born - contaminating this pristine life in which there is only room for two. But they find the ideal solution. What may be one couple's happy ending is everyone else’s indescribable nightmare. Told through the Gutteridges' voices, and those of their families, neighbours, and those who will come across them in the aftermath, this perverse love story hurtles to the heart of evil - the evil that could be anyone’s next door neighbour.
