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 world, 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 reality 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?.
