I have started listening to the
Books on the Nightstand podcast recently. It features two hosts, Ann Kingman and Michael Kindness, who work in the publishing industry and do weekly / biweekly podcast where they spend about 15 - 25 minutes talking about a books that fit a particular theme (graphic novels for someone who hasn't read them, mystery, cookbooks, books that have upcoming films, nonfiction for fiction readers, upcoming books getting a lot of buzz, mid-year favorites, etc.) and a segment at the end where they talk about a book that isn't out yet, but is coming out in the next few months. Of course, listening to the old (2008 - 9) episodes means that those "upcoming" books have been out for years, but I'm still learning about a ton of books that sound interesting, and the hosts are really great at describing the books with minimal spoilers.
