What does it take to make one of the top assassins in the world? How do they become that person? Calisto is on the top of a very short list of people to turn to when justice needs to prevail, when the governments can't do their own dirty work, can't bring justice to light through normal channels. Working through the agency as it is called, she takes the cases on an as agreed basis, makes sure that it is done correctly. To get her to this point, to this level what did it take, how did she become the Calisto that they all count on to make things right. The background, the history and the making of this machine and coming to the realization that within that armor plated shell lies the heart of woman who has been through hell.
