These two classic science-fiction tales from John Wyndham explore the darker side of human nature. In The Chrysalids, ten-year-old David is having strange dreams about a mysterious city. But in his ultra-religious village of Waknut, all abnormality is abhorred, and he soon realizes that differences can be very dangerous indeed. Set in the future, Survival concerns an accident on the first auto-piloted space flight that leaves its passengers cast adrift in space. They have enough supplies to last for three months--but then food starts to go missing. What lengths will the passengers go to in order to survive?
