We’re off for Labor Day weekend, but are excited to bring you a great episode of The Book Review podcast. As part of The New York Times Book Review’s recent 100 Best Books of the 21st Century project, podcast host and Book Review editor Gilbert Cruz has been interviewing some of the authors whose books appeared on the list. In this episode, he talks to Jennifer Egan about her Pulitzer-winning novel, “A Visit From the Goon Squad.” They discuss the early challenges the book faced in finding an audience, the meaning of its title and Egan’s initial reluctance to decide whether the book was a novel or a story collection.
