In the heart of Washington, one deadly secret could topple the presidency and ignite a national crisis.

Captain Luke Steele knows the corridors of power can be as perilous as any battlefield. As a military aide to the president, he carries the nuclear codes and stands at the center of America's most closely guarded secrets. But when whispers of betrayal swirl inside the White House, Luke is drawn into a web of political corruption and hidden agendas that threatens not just the presidency but the stability of the entire nation too.

FBI Agent Amberlyn Reiner never expected her late grandmother to leave behind more than keepsakes. But on Christmas Eve, Amberlyn receives an unmarked box containing her grandmother's jewelry from Eastern Europe, coded documents, and obituaries linking to a string of suspicious deaths. As Amberlyn digs deeper, she uncovers whispers of Cold War poisons, vanished operatives, and secrets someone will kill to bury. What her grandmother knew connects directly to a network that didn't die with the fall of the Iron Curtain.

Together Luke and Amberlyn must follow a trail of hidden alliances stretching from the highest offices in Washington to the quiet streets of Europe. With time running out and enemies embedded within their own government, the two are thrust into a deadly game, where one misstep could cost them their lives—and ignite an international crisis.
