Seven Deadly Wonders by Matthew Reilly

A legend of the ancient world decrees that every 4,500 years, a terrible solar event will wreak worldwide destruction . . . But whoever sets the Golden Capstone atop the Great Pyramid at Giza will avert disaster and gain the ultimate prize: a millennium of world dominance. Now the Sun is turning once again and nation will battle nation to retrieve the missing Capston . . . But a group of small nations, led by super-soldier Jack West Jr., bands together to prevent any one country from attaining this frightening power. Thus the greatest treasure hunt of all time begins -- an adrenaline fueled race on a global battlefield. From the Colossus of Rhodes to the Hanging Gardens of Babylon to the Great Egyptian Pyramid itself, unlock the thrills of Seven Deadly Wonders.
