A (seemingly) post-nuclear world where it is considered a deviation and blasphemy against God to have a genetic mutation (like an extra toe), the book's core meaning is of accepting others even though they are different from you.
The book was not top-tier but it wasn't mediocre either. The plot and concept is genius, an 'abstract' portrayal of a post-nuclear world where our characters grow up. They belong to a uber-religious cult community who considers anything or anyone that doesn't look normal (like a giant horse for example!) a deviation and subject to destruction.
It's a truly captivating story, I enjoyed reading it, especially towards the end where you really get a proper glimpse at what the world they live in is actually like.
I recommend this book to anyone interested in Dystopian novels, and most readers looking for a great message in general.
