I'm a private investigator and not by choice. I dreamed of becoming a police officer my entire life, made the dream reality, and had it taken away by a shoulder injury. Now, I'm snapping pictures of cheating husbands and wives, tracking down people who don't want to be found, and basically working one worthless case after another while trying to make ends meet. Enter Catch Xavier Moon, a dangerous criminal. He's hot and sexy and his world is crime, drugs, and women. Not exactly a combination to turn me on. Now, people I thought of as friends are trying to kill me. Maybe I'm in over my head or maybe not, but Moon isn't the man I want in my life, and his stubborn sexiness has no bearing on the trouble I'm in. Or does it? Contains mature themes.
