 From NPR and WBUR, I'm Lisa Mullins in Boston. I'm Scott Tong in Washington, D.C. This is Here and Now. We are now fully into summer travel season, of course, and you might be looking for something to listen to to get through that train or plane or long car ride. Well, our go-to book expert, Tracy Thomas, has some suggestions for audiobooks. Tracy, of course, is host and creator of the podcast The Stacks, and she's with us. Hey, Tracy. Hi, Scott.
