Jo

Jo has sacrificed everything to save her family. For two years, she has done whatever she is told, no questions asked. In return, her family and friends remain safe from the roving bands of gangs that now prowl the streets of what used to be America.
After showing mercy during one of her assignments, she is given a guardian. A man sent to watch her and make sure she doesn't deviate from her orders again. A man she doesn't understand and refuses to obey.
Her new assignment turns out to be much more complicated than any of her previous ones. In the process of executing her orders, she begins to learn some hard truths about herself. And, for the first time, she begins to question exactly who is giving her the assignments. And why.
But Kerus is keeping secrets of his own. Sworn to not intervene, he finds himself breaking his promises as well. And soon, he must decide how far he is willing to go. And how much he is willing to trust Jo. For unbeknownst to her, the assignments are not what they seem. And the fate of their world may just rest on her success.
