Eric Albright, a twenty-six-year-old unemployed journalist, and Stuart Casey, a homeless old drunk, fall through a door in a graffiti-covered wall into the strange world of Levall, where a mountain-sized dragon with the powers of a god lies sleeping beneath a great white castle. Here they are the otherworlders, Pilgrims, and their lives are never going to be the same again. In the castle the sinister Lord Vous rules with an iron fist as the Project, designed to effect his transformation into an immortal spirit, nears completion. But Vous' growing madness is close to consuming him, as is his fear of the imaginary being named 'Shadow'. And the arrival of the otherworlders in Levall is about to lend substance to that fear. No one has ever seen what lies beyond the impossibly vast Wall that divides Levall, but the Pilgrims possess powers strong enough to break it down. If they do, what will enter from the other side?
