CIA covert operator Savannah James is after intel on a potential coup in the Democratic Republic of the Congo, but she needs a partner to infiltrate the organization. Sergeant First Class Cassius Callahan is the perfect choice, except he doesn’t like or trust her, despite the sparks that flare between them. Still, he accepts the assignment, knowing Savannah will pose as his mistress.

They enter battle-worn Congo to expose the financing for the coup. Betrayal stalks them as they follow the money deep into the heart of a jungle where cobalt, gold, and diamonds fund treason. Savannah will stop at nothing to bring down the would-be dictator before he can ignite a firestorm that will engulf all of Africa.

Deep in the sultry rainforest, spy and Green Beret forge a relationship more precious than diamonds, but Cal knows Savannah is willing to sacrifice anything—or anyone—to complete her mission.
