Book Three of the Chronicles of Aesirium: The great and overwhelming Wall which enforces the exile of the people of Oldtown-Against-the-Wall also protects a substantial secret: namely, the lives and life which has also proceeded on inside the Wall. The citizens of Aesirium, protected by the Wall, are content within their relative ignorance; until a new threat reveals itself among them. Rom and her friends must investigate and defend themselves against the mysterious sandmen, following their trail out beyond the streets of Oldtown, the Wild and into the City of the Dead.
