During the last fifty years, the level of the Dead Sea has dropped more than fifty feet, and land that has not been explored in over ten thousand years is suddenly dry and exposed. It reveals something never before seen by modern eyes, an immense cavern buried in the old sea floor, the walls of which have been carved with millions of perfect circles. Tan Wu is sent to investigate, and struggles not only to uncover the meaning behind the massive inscription, but also to set the information free as the world’s governments and violent religious factions bear down on him to keep it hidden. What he discovers changes the world and everything we know about ourselves.
