This week on planet money, we're going to give our listeners a little peak behind the curtain. Every time we hear an episode in our feed, that is often just the tiniest tip of the iceberg of all the stuff we've been researching and reading for this show. So why not let our listeners in on our unofficial club, plenet money book club? We'll each share a book we're reading and why we think it's fascinating. Everything we are going to talk about will be linked in the notes of this episode.
