"If this is Paradise, how bad could Hell be?" A sandstorm uncovers a long buried secret in the Iraqi desert, an ancient Sumerian temple dating back at least 6,000 years to the beginning of civilization. An American army patrol sent to investigate the ruins is trapped inside the temple's eroded walls, first by an insurgent ambush then by another, even more powerful sandstorm. When an enemy mortar shell blasts an opening into a hidden burial chamber, Captain Adam Cadman and his soldiers take refuge deep in the ruins. What they find hidden inside threatens to destroy every belief about the beginnings of mankind-as well as modern society as we know it.
