If you could see the world around you entirely as A mathematical equation, would it be a superpower or a curse? Fifteen year old Mbele lives in a squatter's village called Broobrishanto, high atop the Brooklyn Bridge, not too far in the future. When he falls from the bridge into the poisonous East River he is marked for life with blue tinted skin that gets darker when he sweats. With the blue skin come strange visions that blind him to the world we see and replace it with math. When one of his visions drives him to defy the leader of the bridge's notorious Booted Ones gang, Mbele has one choice - RUN If it weren't bad enough that he stands out in a crowd and gets lost in algorithmic visions, he's also looking after his four year old, loud-mouth sister Skye. Desperate to protect his sister, rid himself of visions, and find a way home, he searches the streets of New York City for the one person he believes can help him. Along the way he befriends a charming con artist, a girl who creates new skins for people, and a mentor who is not quite what he seems. Together, they discover a much more dangerous threat than the gang he ran away from - an enemy that lives "in the blue."
