They say opposites attract - but that certainly isn't the case with these two assassins.When a dangerous enemy emerges as a threat to DUO and its operatives, Mac and Dink will be called upon to stop the Heretic and his revenant army from destroying Philadelphia's Mummer's Parade and possibly DUO itself.Fortunately for DUO, they only recruit the best of the best. Even if some teams don't start out as the best of friends.Dink insists on following protocol. His rigidity forces him to see everything in black and white. He won't even add milk to his tea because anything cloudy causes his keister to clench.Mac prefers to live life in the gray zone. Kicking ass, bending rules to take out the bad guys by whatever means necessary, and stuffing her piehole as often as possible along the way.But they'll have to quit bickering long enough to get the job done.Once the two become one, their unique talents become a whole new level of awesome.But will it be enough to take down the Heretic and his army?Can this testy twosome bury their personal feelings about each other before the bad guys bury us all?.
