Blackout (Darkness Trilogy, #1)

One wall divides life from darkness. After the worldwide Blackout, America built a concrete wall--the Frontier--across the middle of the nation to isolate its precious electricity in the top half. Everyone below the Frontier was forsaken, and now only a few survive in the grim region known as the Dark Zone.

Sixteen year old Phoenix Troublefield endures the dark with his girlfriend, Star Windsong. When America announces that it will trade electricity for immigrants, Phoenix and Star sacrifice themselves for the power that might save her younger brother. On the other side of the Frontier, they find America is not what they expected, and instead they are thrown into a shocking and deeply personal contest that threatens to destroy their love. When the chance comes to escape back into the Dark Zone, it may already be too late.
