Under the Never Sky
Exiled from her home, the enclosed city of Reverie, Aria knows her chances of surviving in the outer wasteland—known as The Death Shop—are slim. Then Aria meets an Outsider named Perry. He's wild—a savage—and her only hope of staying alive. A hunter for his tribe in a merciless landscape, Perry views Aria as sheltered and fragile—everything he would expect from a Dweller. But he needs Aria's help too; she alone holds the key to his redemption.
I really liked this first book. It reminded me of the hunger games series. It takes place in a 2 different "worlds". One where there is technology, and another where there is not. The plots revolves around Aria, a dweller, and Perry, an outsider. It is full of adverture, some romance, and lots of action. A worthy read.
