'I don't kill the innocent. I don't hunt the desperate, or the broken. I don't hunt people trying to survive a world that's already stacked against them. I hunt monsters of the worst kind'. - Panther - At just 23 years old, Ruby Eleena stood as the world's most elite assassin. Unlike the others in similar profession, who readily sold out for the highest bidder, her targets had to meet specific criteria. At 19, her life was violently shaken, leaving her devoid of emotions and turning her into a solitary figure who only accepted contracts that targeted predators. Theodore Eagle was the CEO of one of the biggest pharmaceutical companies in the States and Europe. Behind the scenes, he had a hidden "trade". Self-centered, arrogant, and ruthless in his operations, with another "side" to him. When the world's deadliest assassin crosses paths with one of the most dangerous men alive, neither of their lives will ever be the same.
