The third and final book in Lauren Oliver's powerful New York Times bestselling trilogy about forbidden love, revolution, and the power to choose.

Now an active member of the resistance, Lena has transformed. The nascent rebellion has ignited into an all-out revolution, and Lena is at the center of the fight.

After rescuing Julian from a death sentence, Lena and her friends fled to the Wilds. But the Wilds are no longer a safe haven. Pockets of rebellion have opened throughout the country, and the government cannot deny the existence of Invalids. Regulators infiltrate the borderlands to stamp out the rebels.

As Lena navigates the increasingly dangerous terrain of the Wilds, her best friend, Hana, lives a safe, loveless life in Portland as the fiancée of the young mayor. They live side by side in a world that divides them until, at last, their stories converge.

Lena fights for a future with feeling, while Hana lives in a world without it. When their paths cross, who will have to sacrifice everything?

• Love Triangle: A boy from her past has returned, changed and hardened by the government's prisons. A new love offers her a different future. Lena is torn between the boy she lost and the one she saved.
• Friends to Enemies?: Once inseparable, Lena and Hana now stand on opposite sides of a revolution. As their worlds collide, their long-buried friendship will be tested like never before.
• Forbidden Love: Lena once risked everything for a love that was declared a disease. Now, she must decide what-and who-is worth fighting for.
• All-Out Revolution: The resistance is no longer hiding in the shadows. From the dangerous Wilds to the heart of the cities, the final battle for the freedom to love has begun.
