The National Book Foundation's 5 Under 35 is an annual program that honors five outstanding young authors. Each year, these writers are recognized for their exceptional work and potential to shape the future of literature. The selected authors are chosen from a pool of nominees by previous National Book Award winners and finalists. The program aims to highlight emerging talent in the literary world and promote their books to a wider audience. By celebrating these authors, the National Book Foundation seeks to encourage readers to discover new voices and support the next generation of writers.
