AILSA CHANG, HOST:
So, Mary Louise, have you read any good books lately?
MARY LOUISE KELLY, HOST:
I have, actually - tons of good books this year. But you know who has read way more, I'm guessing, than you or me?
CHANG: Oh, I already know. NPR book editor Petra Mayer, right?
KELLY: Who - yes, indeed. And believe it or not, she is here with us to talk about the fruits of her labor, not to mention the labor of many, many others here at NPR; the NPR Book Concierge, which is now live.
