The first look is enough to make me impatient to get my hands on this book. As a mom, I know that no one knows my kids as well as I do. No one could ever swap them for other kids, even if they looked exactly the same, w/o my knowing. I'm sure the mom in this book feels the same way and is willing to do anything to get her babies back. I know this would be totally terrifying and that enough is the tension needed to be a great thriller.
