One Book, One Philadelphia is a signature project of the Free Library of Philadelphia that promotes literacy, library usage, and civic dialogue by encouraging the entire greater Philadelphia area to come together through reading and discussing a single book.

From April 20 to June 22, dozens of free-to-the-public events, discussions, and creative workshops will center on Charles Yu's novel, Interior Chinatown, and the youth companion titles American Born Chinese by Gene Luen Yang and Drawn Together written by Minh Lê and illustrated by Dan Santat.

Along with presenting two companion books that invite younger readers into the citywide conversation, One Book, One Philadelphia offers curricula, discussion guides, and supplemental reading lists for all ages that connect with the themes in the featured books.
