The novel “The Chrysalids”, known in the USA as “Re-Birth”, by John Wyndham was published for the first time in 1955.

David Strom learned very well the religion lessons that his father, the preacher from the village of Waknuk, gave him. This means that he’s perfectly familiar with the Definition, which establishes the characteristics of a human being. However, when he discovers that Sophie, a little girl from a nearby community, has six toes, he doesn’t think she’s a sacrilegious mutant. When Sophie’s mutation is discovered, adults don’t react with David’s levity.

Over the years, David develops telepathic abilities that allow him to communicate with other young people in the area with similar power. Sophie’s story taught him the hard way that any out-of-the-ordinary traits that could be considered a mutation must be kept secret and the other Telepaths agree with him. The birth of his sister Petra, who starts manifesting very soon extremely powerful telepathic powers that allow her to contact people at a far greater distance, changes their situation.
