The 15th annual City Lit Festival Saturday, April 14, will include scores of sessions for writers and for readers. City Lit Project director Carla Du Pree gives highlights, which range from stories about motherhood and racial, gender and socioeconomic “passing” to one-on-one editing sessions with established writers and a master class with poet Yrsa Daley-Ward about fearlessly writing your truth. Then keynote speaker Phillip Gourevitch talks about his upcoming book on what the aftermath of the Rwandan genocide teaches about memory, forgetting and hiding.
