John Wyndham's 1955 novel "The Chrysalids" (United States title: "Re-Birth"), set in a small community untold centuries after a nuclear holocaust (not expressly told, but strongly hinted at with genetic mutations, glowing ruins, landscape baked to glass), tells the story of David, part of a small group of teens who share a limited form of telepathy that allows them to communicate with others who have the same talent. However, the fundamentalist society they live in, regards the slightest difference from the norm as a blasphemy and affront to God. The group attempt to remain hidden, then failing that, survive during a war between mutants and the fundamentalists while waiting for members of a distant advanced telepathic human civilization to rescue them.
