Chrysalids (Penguin Books)

The disturbing post-apocalyptic novel "The Chrysalids" aby 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.

"Perfect timing, astringent humour...one of the few authors whose compulsive readability is a compliment to the intelligence". ("Spectator"). "Remains fresh and disturbing in an entirely unexpected way".
