A graphic novel with an imaginative, do-it-yourself theme has been chosen as the 2019 Youth One Book, One Denver winner, Mayor Michael Hancock announced Thursday morning. “Cardboard Kingdom,” by Chicago-based author and artist Chad Sell, will be available for free to children aged 9 to 12 who participate in Youth One Book One Denver (YOBOD), running June through August. The summer reading program aims to “combat learning loss through events and activities tied to the book’s themes, ” according to a Denver Arts & Venues news release. There’s no need to formally sign kids up for the program.
