The Chrysalids

In a post-apocalyptic Labrador, the survivors live by strict religious beliefs and practice eugenics to maintain "normality." Mutations are considered blasphemies and punished. David, a telepathic boy, befriends Sophie, who has a secret mutation. As they face persecution, they escape to the lawless Fringes. With the help of telepaths and society in "Sealand," they evade hunters, find rescue and plan to return for Rachel, another telepath left behind in Waknuk.
