The arm of a dead body points down Chicago's Adams Street, also known as Route 66. Along this road of many names, a silent caravan of cars drives. They are parents of missing children, all brought together by word that children's grave sites are being discovered along the road. And they are being shepherded by detective Kathy Mallory of the NYPD. But the child Mallory seeks is not like the others. It is herself the feral child adopted off the streets, her father a blank, her mother dead and full of mysteries. During the next few extraordinary days Mallory will find himself hunting down a killer like none she has ever known and will discover more about herself than ever before.
