My name is Eve Hamilton and I live in Compound Eleven.

Here, the hierarchy of the floors is everything. And on my floor, we fight-which is better than the bottom floor, where they toil away in misery. Only the top floor has any ease in this harsh world; they rule from their gilded offices.

All because four generations ago, Earth was rendered uninhabitable-the sun too hot, the land too barren. Those who remained were forced underground. While not a perfect life down here, I've learned to survive as a fighter.

Except my latest match is different. Instead of someone from the circuit, my opponent is a mysterious boy from the top floor. And the look in his eyes tells me he's different, maybe even kind...right before he kicks my ass.

He could be my salvation. He could be my undoing. Because I'm no longer content to just survive in Eleven. Today, I'm ready to fight for more than my next meal. I'm fighting for my freedom. And this boy might just give me the edge I've been waiting for.
