Srinath, Suresh, and Harleen live at the Guild of Orphans. After a particularly bad scuffle, the children begin to feel the building of their Guild begin to rumble. They fall out the window to see their building, and others like it, walking away. To make matters worse, the moving giants have taken their friend Kishore captive. Following a trail strewn across the City of Rubble, the trio stumbles from one adventure to the next. The children encounter men with evil designs, an auto driver like no other, and a centuries-old source of power, as they quest to rescue their friend in this fast-paced children's book.
