In an alternate United States, love has been declared a dangerous disease, and the government forces everyone who reaches eighteen to have a procedure called the Cure. Living with her aunt, uncle, and cousins in Portland, Maine, Lena Haloway is very much looking forward to being cured and living a safe, predictable life. She watched love destroy her mother and isn't about to make the same mistake.
But with ninety-five days left until her treatment, Lena meets enigmatic Alex, a boy from the Wilds who lives under the government's radar. What will happen if they do the unthinkable and fall in love?
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.
