The "Underground" is a place where the sky, sun, and moon do not exist, and therefore neither do day or night. A place where a person- if not poor- takes a test to find out the 'Division' that they shape their lives around: Fighter, Leader, Intelligent, Undercover, or Special.
Kaye is an sixteen year old girl, orphaned as a child, and living in the Gang District. She's never bothered to take the Government's Division test, preferring to instead use the training she's gotten from her gang to protect the poor and homeless that make their home in the Old Housing District. It's there that she meets Nico, a ten year old Leader, who's stolen The Cure for his sickly sister. When Kaye decides to help Nico, the stolen vaccine brings unwanted attention to the both of them- as well as their families.
Driven from their homes by the Almighty, the mysterious head of the Government, Kaye and Nico, along with his two older siblings, are forced to find refuge. Their quest brings up the Aboveground- a 'mythical' place only told about in stories. It's a dangerous journey to get to it- once that may very well be all for naught- but it's their last chance to get away from the government who covets them.
But as they struggle to survive their journey to the Aboveground, their last hope could very well lead them to their demise.
Elliot Jensen and Elliot Fintry have a lot in common. They share the same name, the same house, the same school, oh and they hate each other but, as they will quickly learn, there is a fine line between love and hate.
