When a new NASA satellite spots evidence of an astonishingly rare object buried deep in the Arctic ice, the floundering space agency proclaims a much-needed victory…a victory that has profound implications for U.S. space policy and the impending presidential election. With the Oval Office in the balance, the President dispatches White House Intelligence analyst Rachel Sexton to the Milne Ice Shelf to verify the authenticity of the find. Accompanied by a team of experts, including the charismatic academic Michael Tolland, Rachel uncovers the unthinkable: evidence of scientific trickery — a bold deception that threatens to plunge the world into controversy.

When the NSA’s invincible code-breaking machine encounters a mysterious code it cannot break, the agency calls its head cryptographer, Susan Fletcher, a brilliant and beautiful mathematician. What she uncovers sends shock waves through the corridors of power. The NSA is being held hostage…not by guns or bombs, but by a code so ingeniously complex that if released it would cripple U.S. intelligence.
