Every weekday morning since late September, NPR’s Book of the Day podcast has welcomed authors to discuss their books. From Hillary Clinton and Louise Penny, on their political thriller, to actor Nick Offerman, on his love letter to the great outdoors, and the poet Melissa Lozada-Oliva, on her Selena Quintanilla fan fiction, each episode—20 minutes or less—offers a glimpse at a new release. The interviews are funny, thought-provoking, and easy on the self-promotion. —Jacob Robbins
