Lena has transformed. Once a fugitive, now a pivotal member of the resistance, she stands at the heart of a rebellion that has ignited into all-out revolution.

After daringly rescuing Julian from a death sentence, she and her friends escape to the Wilds—but nowhere is safe anymore. The Wilds are under siege, pockets of rebellion spark across the country, and the government can no longer deny the existence of the Invalids. Regulators infiltrate the borderlands, determined to crush the rebels.

Meanwhile, in Portland, Lena's best friend Hana lives a safe yet loveless life, engaged to the young mayor. Two lives running parallel in a fractured world.

As their paths draw closer, the fate of their world hangs in the balance. When their stories converge, choices must be made—but will they unite or stand divided?
