A light is on the horizon...Salvador Sebastian's Great Dark has persisted for two years, despite the American Liberation Effort's growing network across the North American continent. The Leftys lost their leadership at Camp Forager outside Kansas City, a vicious blow that showed just how strong ANTI- really was. But a small group of Lefty survivors, led by the inspirational young girl Jessica, struck back, taking out one of the ANTs' military drone bases in Kansas. After the successful counterattack, she and the others escaped to Texas, where Camp Alamo became the new Lefty capital. But Simone Vincent, Salvador's second-in-command, has traveled to Texas, too, ready to act on her leader's orders whenever they come.Meanwhile, Henry has helped his mother Meg defeat her cancer, bringing her back from the brink of death. The family farm has been their refuge for a year, where they have grieved the loss of their patriarch and assumed the worst for Jessica. But that all changed with the arrival of Quinn Connors, Meg's father who lived a secret life as an ANT for decades. He held a knowledge that coaxed Meg and Henry from the farm - the knowledge that Jessica was still alive, and that they could maybe save her from the war against Salvador that she had been fighting.The final installment in the Overthrown trilogy brings the family of Jessica, Henry, and Meg together again, only to tear them apart as they face the man that created the darkness. Jessica and Henry each have a choice to make, and a mission to accomplish. And if either one fails, a new light will illuminate the world - one brought on by Salvador Sebastian himself, and one that will be worse than any darkness could ever seem.
