Summary: When Will and his friends arrived at the White Mountains, they thought they’d found a safe haven where the mechanical monsters called Tripods could not find them. But in order to save everyone else they'll have to journey to the Tripod capital: the City of Gold and Lead. Although the journey will be difficult, the real danger comes once Will is inside the city, where Tripods roam freely and humans are even more enslaved than they are on the outside. Without anyone to help him, Will must learn the secrets of the Tripods before they figure out that he’s a spy.
