<br/><br/> "As David and Rosalind grow older it becomes more difficult to conceal the differences which would label them as mutants from the village elders. Soon they face a choice: wait for eventual discovery, or flee to the terrifying and mutable Badlands..."  "The Chyrsalids is a post-nuclear apocalypse story of genetic mutation in a devastated world and explores the lengths the intolerant will go to to keep themselves pure."-Back cover
