When the Prince of Denmark is murdered in the Florida Keys, an unlikely duo of American and Irish diplomats in Copenhagen becomes embroiled in a deadly game of espionage, ancient conspiracies and high stakes diplomacy as they confront one of the West’s most dangerous enemies. In Reign of Secrets, Colonel Whit Ransom and Irish attaché Aisling Kelly race across Europe to stop the Russian President and his assassins as they chase the Danish Crown’s most guarded treasure, a thousand-year-old secret that could threaten the royal houses of Europe and return the Russian empire to glory.

In Reign of Secrets, diplomacy meets danger, and the past may be the deadliest weapon of all.
