Geetanjali Shree’s International Booker Prize-winning novel is an homage to the vibrancy of Hindi that threatens to lose its shine in a globalized world. Two decades ago, Arundhati Roy was the first Indian citizen to win the Booker Prize for her haunting novel “The God of Small Things.” Now, Geetanjali Shree amplifies the country’s Western literary acclaim with “Tomb of Sand,” her International Booker Prize-winning novel originally written in Hindi and translated into English by Daisy Rockwell.
