The country is at war. Beset by enemies within and without. And all because of the decisions changed by one boy, Scott Tyler. In this ravaged alternative reality, Scott hardly recognises himself. He’s a war hero, a leader of a unit of Shifters and maybe the only one who can prevent the country’s frail defences from crumbling. But all Scott wants to do is find a way back to the world he knew, without losing the girl he loves. With every Shift he makes, Scott edges closer towards oblivion. With no one to trust – not even himself – how much is he willing to risk to get home?
