The ODA Prime Unit by Kelly Koval

As the first female Special Forces Sergeant, Kari Anderson was used to overcoming obstacles, but nothing compared to the hurdle that was Brice Evans. Charming and arrogant, Brice had already formed his opinion of Kari the moment he laid eyes on her, and he was not one to change his mind. At the peak of their dissonance, everything they believed about each other would be put to the test when they would find themselves stranded in the jungle together, the impossible task of preventing a war in front of them, needing to overcome impossible odds and figure out how to become a team.
