Outpost (Razorland Trilogy #2)

Deuce's whole world has changed. Down below, she was considered an adult. Now, topside in a town called Salvation, she's a brat in need of training in the eyes of the townsfolk. She doesn't fit in with the other girls: Deuce only knows how to fight.

To make matters worse, her Hunter partner, Fade, keeps Deuce at a distance. Her feelings for Fade haven't changed, but he seems not to want her around anymore. Confused and lonely, she starts looking for a way out.

Deuce signs up to serve in the summer patrols—those who make sure the planters can work the fields without danger. It should be routine, but things have been changing on the surface, just as they did below ground. The Freaks have grown smarter. They're watching. Waiting. Planning. The monsters don't intend to let Salvation survive, and it may take a girl like Deuce to turn back the tide.
