Paperback. Condition: new. Paperback. Some doors are hidden for a reason. Others are sealed to protect the world from what lies behind them. When Avi uncovers a mysterious structure long dismissed as myth, he believes it to be nothing more than a forgotten relic. But the door was never abandoned-it was designed to wait. Across g…enerations, the Noor family has guarded fragments of a truth too dangerous to be written down: the knowledge to rebuild a lock that cannot be forced, only understood. As ancient engineering collides with modern ambition, Avi is pulled into a race against time that stretches across continents and centuries. Each discovery tightens the grip of a mechanism built with a singular purpose. Because the first door is not the only one. And opening it may be the last choice anyone ever gets to make. This item is printed on demand. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.
