When she decides to resign after years of working, the new heads of the agency- Ian's grandchildren- give her a condition; Undergo one more task, or remain. She chooses the former. The result is to tackle a group of people she never knew existed on this earth... Ivory had been trained in warfare ever since she was little by Ryan Deville. Now that she's ready to leave that life, his grandchildren make it hard for her. To leave means death. They'll have pity on her, but on one condition.
