The United States is gone, along with its flooded coasts. North America's two warring nations, the western Republic and the eastern Colonies, have reached a breaking point. In the midst of this broken continent and dark new world are two teenagers who will go down in history ...Born into the slums of the Republic's Lake sector, fifteen-year old Day is the country's most wanted criminal. He is: a mysterious boy with no recorded image or fingerprints, a boy who should no longer exist, and a boy who watches over his family until one evening, when the plague patrols mark his family's door with an X - the sign of infection. It is a death sentence for any family too poor to afford the antidote. Day has no choice; he must steal it. Born to an elite family in the wealthy Ruby sector, fifteen-year old June is the Republic's most promising prodigy. Obedient, passionate, and committed to her country - until the day her brother Metias is murdered during a break-in at the plague hospital. Only one person could be responsible. Day. And now it's June's mission to hunt him down. The truth they'll uncover will become legend.
