In the mysterious City of Towers, the center of the destroyed Tarakan empire, a lowly scribe of the Guild of Historians is charged with a dangerous assignment. He must venture into the wilds beyond the glass and steel towers to discover the fate of a child who mysteriously disappeared more than a decade before. Born of a rare breed of marked people, the child, Rafik—known as “The Key”—was one of a special few with the power to restore this lost civilization to glory once again. In a world riven by fear and violence, where tattooed mutants, manic truckers, warring guilds and greedy mercenaries battle for survival, this one boy may have singlehandedly destroyed humanity’s only chance for salvation—unless the scribe can figure out what happened to him.
