Summary: "In a stratified society where contact with the sun is a luxury reserved for the elite, those kept prisoner in the darkness will do anything to find the light. Arden--beautiful, street-smart, and cynical--is one of the citizens of the lowest level, known as Undercity, of an off-world colony. A blackout band traps Arden in her district, but as sister to the leader of the most powerful gang in Undercity, she has access to the Above. There she meets Dade, one of the few lucky enough to be born into the sun-kissed families who reside in the towers soaring above the rest of the city. But life isn't perfect in the sky.

An unlikely romance develops between the two teens--but their love faces opposition from above and below..."--Page 4 of cover.
