Furtive Rebels - The Black Ops Series, #1

Oliver Anderson is a former black-ops operative turned Private Investigator who mostly helps people on the wrong side of the law get away with shady deals. He  doesn't seem to care much about following rules anymore. His soul has been tainted by an imperfect system he now hates. That is until Agent Mila Jenkins gets sent undercover to look into his practice and singular way of dealing with things, just as one of the biggest criminal master plans the country has ever seen is slowly unfolding.
In a world ruled by chaos and deception, enemies lurk in the shadows, the line between right and wrong gets blurrier at each passing second, and trust doesn't come easy. In the midst of such adversity, Oliver and Mila's beliefs will soon be tested. For better or worse, he is mayhem, she is turbulence. Will it be their demise? Or will it make them stand stronger?One thing is for sure: they'll have to face their truths and all it entails whether they're ready for it or not.
