NEW YORK — Kiran Desai, acclaimed author and recipient of the Booker Prize, is set to release her latest work, “The Loneliness of Sonia and Sunny,” next fall. This marks her first foray into fiction since her award-winning novel, “The Inheritance of Loss,” which debuted almost two decades ago. The new book is slated for publication in September by Hogarth, a division of Random House Publishing Group.

Desai describes “The Loneliness of Sonia and Sunny” as a vast narrative that explores the journeys of two Indian individuals navigating life in the United States against a backdrop of personal challenges and historical contexts. In her own words, she elaborates that the novel “uses the comic lens of an endlessly unresolved romance between two modern Indians” to delve into the complexities of love and isolation as they manifest within the intricacies of today’s interconnected world. Desai emphasizes the unique capability of novels to expose the authentic emotions and negotiations people experience privately.

Having made her literary debut in 1998 with “Hullabaloo in the Guava Orchard,” which presents a humorous tale of a man who opts to live in a tree, Desai received widespread recognition eight years later for “The Inheritance of Loss.” The novel, published in the U.S. by Atlantic Monthly Press, follows the intertwined stories of an undocumented Indian immigrant in the United States and an Anglicized Indian living in West Bengal. At the age of 35, Desai became the youngest woman to win the Booker Prize, alongside receiving the National Book Critics Circle Award for her impactful storytelling.

David Ebershoff, Desai’s editor at Hogarth, shared insights about the new book, describing it as “an expansive tale of multiple generations,” blending emotional depth with intellectual engagement. Through this work, Desai aims to capture the essence of human experience in a fast-paced, global environment, making it not only a personal narrative but also a pertinent social commentary.
