Jonathan Lethem, the bestselling author of twelve novels, including “The Fortress of Solitude” and “Motherless Brooklyn,” has often focused his books on the Brooklyn neighborhood he grew up in. His newest, “Brooklyn Crime Novel,” makes the neighborhood a main character. The book examines gentrification, nostalgia and race, among other topics. Lethem spoke to Dave Miller in front of an audience at the 2023 Portland Book Festival.
