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. Requiem is told from both Lena’s and Hana’s points of view. They live side by side in a world that divides them until, at last, their stories converge.
