When Conner Pennington—a private investigator specializing in cold cases—gets a desperate call from his favorite cousin, he learns that her husband, Michael MacKenzie, a former Navy SEAL, hasn’t been heard from since he left for a business trip two weeks earlier. Given her husband’s history, Patty does not want to involve the police. And she knows Conner is her best hope to find him alive.

During the 1980s, MacKenzie and Colonel Oliver North, USMC, ran successful operations in Nicaragua in an effort to discredit the Russian Spetsnaz operatives, but now the Russians have returned to Nicaragua, with the full intent of carrying out spy operations against the United States. Large sums of cash, jewels, gems, and gold bars were used by the US and Russia to influence the Nicaraguan regime in the eighties, and over four million dollars in assets were stolen from the Russians. Those riches were never found after North and MacKenzie left Nicaragua, and the tantalizing treasure awaits recovery. Now, Conner must assemble his own team and head to Nicaragua in hopes of skirting the Russians and bringing MacKenzie home—alive.
