Heralded for masterfully intermingling science, history, and politics in his critically acclaimed thrillers The Da Vinci Code and Angels & Demons, New York Times bestselling author Dan Brown has crafted another pulse-pounding novel in which nothing is as it seems -- and behind every corner is a stunning surprise.

A shocking scientific discovery. A conspiracy of staggering brilliance. A thriller unlike any you've ever read....

When a NASA satellite discovers an astonishingly rare object buried deep in the Arctic ice, the floundering space agency proclaims a much-needed victory -- a victory with profound implications for NASA policy and the impending presidential election. To verify the authenticity of the find, the White House calls upon the skills of intelligence analyst Rachel Sexton. Accompanied by a team of experts, including the charismatic scholar Michael Tolland, Rachel travels to the Arctic and uncovers the unthinkable: evidence of scientific trickery -- a bold deception that threatens to plunge the world into controversy. But before she can warn the President, Rachel and Michael are ambushed by a deadly team of assassins. Fleeing for their lives across a desolate and lethal landscape, their only hope for survival is to discover who is behind this masterful plot. The truth, they will learn, is the most shocking deception of all.
