British teenager Nick Moreland stumbles out of the woods, scared and alone—the only witness to a shocking crime that the local sheriff seems determined to conceal. When the perpetrators realise he can identify them, Nick finds himself hunted across the South, through the swamps of Louisiana, even to the depths of the Grand Canyon. Travelling with Maria Juaréz, the smart and feisty companion he meets along the way, Nick must learn to take control of his journey—and his life—if he is to survive.
