ANIMAL’S PEOPLE By Indra Sinha

The story's narrator, a 19-year-old orphan who was born just a few days before the catastrophe and whose spine has become severely bent, must now walk on all fours. "I once was human," says Animal, who is known to everyone simply as Animal. I am informed as such. People who knew me when I was younger say that I walked on two feet, just like a human person, though I don't recall this for myself.https://www.nytimes.com/2008/03/09/books/review/Mishan-t.html
