UnDivided (Unwind Dystology Series #4) by Neal Shusterman

The fate of America hangs in the balance in the fourth and final book in the New York Times bestselling Unwind Dystology series by Neal Shusterman. Cam was only the start of Proactive Citizenry's plans for rewound teens. The corrupt company is planning to mass-produce rewound teen soldiers, and to keep their profitable plans from being interrupted, they've been suppressing technology that could make unwinding completely unnecessary. When Conner, Risa, and Lev uncover these startling secrets, enraged teens march on Washington to demand justice and a better future. But more trouble is brewing. Starkey's group of storked teens is growing more powerful and militant with each new recruit. And if they have their way, they'll burn the harvest camps to the ground and put every adult in them before a firing squad.
