We have three author interviews today. 1) Michael Johnston talks about the latest book ("Grave Danger") in his Confessions of a Dork Lord series. 2) Sonia Monzano (Sesame Street) talks about her National Geographic book "A World Together." 3) From way back in 2003 comes an archival interview with Jonathon Stroud, the author of the wildly popular book series "The Bartimaeus Trilogy."
