Kyle Harper is an historian who focuses on how humanity has shaped nature, and vice versa. He’s a Professor of Classics and Letters at the University of Oklahoma and the author of several books, including The Fate of Rome: Climate, Disease, and the End of an Empire, and his latest, Plagues Upon the Earth: Disease and the Course of Human History. His mastery of the science is only matched by the ease of his prose. If I were to nominate a book of the year, it would be this one (alongside Jamie Kirchick’s Secret City).
