The 2019 Pulitzer for Fiction was awarded to Richard Powers for 'The Overstory'. In this book, Powers delves deep into the world of trees and the people whose lives are intertwined with them. He uses a complex narrative structure that draws the reader in and makes them consider the importance of nature in a whole new light. The Pulitzer committee must have seen the value in his exploration of environmental themes, his character development, and his overall storytelling ability.
Colson Whitehead claimed the 2017 Pulitzer Prize in Fiction for 'The Underground Railroad'. This book received high praise for its powerful storytelling and exploration of important themes.
It's hard to pinpoint a single winner as there are multiple. But authors like Richard Russo for 'Empire Falls' and Marilynne Robinson for 'Gilead' have claimed the Pulitzer Prize for fiction.
