If meeting a best-selling young-adult author who values diversity and whose debut novel has already been made into a motion picture is on your bucket list, prepare to check it off. Drop Everything, Everything and head to the Carnegie Library Lecture Hall for a book-signing and lecture with Nicola Yoon. Today’s program, part of Pittsburgh Arts & Lectures’ Words and Pictures series, is followed by a signing. Yoon’s latest book, The Sun Is Also a Star, won honors including the Coretta Scott King New Talent Award. - Lauren Ortego
