The Navigator is by Eoin McNamee. The first book in The Navigator trilogy. Owen is a young boy whose father died in a terrible accident. He often goes off into the woods to his own special den. One day he sees a strange uniformed man in the woods. The man tells him "It has begun" and Owen finds himself involved with a group of Resisters who are trying to keep the evil Harsh from destroying time itself. The Resisters, or some of them at least, believe Owen is the Navigator, the only one capable of stopping the Harsh. A cute series young boys will enjoy.
