When David's 11-year-old nephew, Andrew, goes missing and David finds the finger pointed at him, he has no choice but to strike out on his own - an unlikely vigilante running away from the police and his own family, and running towards what he hopes desperately is the truth about Andrew's disappearance. David Kingsgrove is a man on a mission. An ordinary man - and an extraordinary mission. It is a mission that will turn him into someone he never thought he would be: the king of the road, the loner on the highway, the crusader for a sort of justice he has never had to seek before. Time is not on his side. But David doesn't need time - he just needs to find Andrew. Andrew had been a regular visitor to David's home right up until the day he disappeared, walking out David's front door to visit a neighbour. It doesn't take long for the police to decide that David - a single man in his thirties, living alone - is their suspect. Soon David's own family - Andrew's parents - will share that opinion. But David knows that he didn't take Andrew. Realising that the only way Andrew will be found is if he finds him - the police, after all, are fixated on David as their suspect and are not looking anywhere else - David turns to the one person who he knows will help him: Matty an ex-cop now his personal trainer, whose own son disappeared several years before. David sets out on the road, frantically pursuing the leads he has discovered, knowing all the while that it may be too late. David's crusade to find Andrew will also take him into his own dark heart - to do things he never thought he would have to do, and go places he has never wanted to go. And the choices David makes lead us all to ask: How far would I go to save someone I love? This is a compelling story that is almost impossible to stop reading - a hero's journey, of sorts, with a momentum that is breathtaking even while the subject matter is confronting.
