Collateral Damage by Nicole Morgan

RJ Hancock had been working undercover for over three years. On paper, and as far as America knew, he was a deserter, a soldier who went AWOL and abandoned his country and unit. There were only a few people in the Pentagon who knew the truth.
Monica Tovar spent her days doing what she was told. That was the way things were done in her family. The men led, while the women followed. It was a pattern that she was growing increasingly tired of.

After years of living on the wrong side of the law, RJ is finally close to completing his mission. But, when Monica comes in the picture he is forced to rethink his priorities. And the lines between duty and honor will be tested.
