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.
Caught in an accelerating tempest of secrecy and lies, Susan Fletcher battles to save the agency she believes in. Betrayed on all sides, she finds herself fighting not only for her country but for her life, and in the end, for the life of the man she loves.
From the underground hallways of power to the skyscrapers of Tokyo to the towering cathedrals of Spain, a desperate race unfolds. It is a battle for survival--a crucial bid to destroy a creation of inconceivable genius...an impregnable code-writing formula that threatens to obliterate the post-cold war balance of power. Forever.  aCryptography vFiction9675752  aIntelligence service vFictionzUnited States9675753  aThrillers (Fiction)9674599  2nmlcMONO  c18260d18260  00102nml40708FICaWPRObWPROcMezd2025-04-24edonationl0oFIC BRO DigitalpFIC0163r2025-04-24 17:07:23t1w2025-04-24yMONO
