The Chrysalids: John Wyndham

The disturbing post-apocalyptic novel The Chrysalids by John Wyndham, author of The Day of the Triffids and The Kraken Wakes and dramatised on BBC Radio 4.

David Strorm's father doesn't approve of Angus Morton's unusually large horses, calling them blasphemies against nature. Little does he realise that his own son, and his son's cousin Rosalind and their friends, have their own secret abberation which would label them as mutants. But as David and Rosalind grow older it becomes more difficult to conceal their differences from the village elders. Soon they face a choice: wait for eventual discovery, or flee to the terrifying and mutable Badlands. . .

The Chrysalids is a post-nuclear apocalypse story of genetic mutation in a devastated world and explores the lengths the intolerant will go to keep themselves pure.
