I've lived in Philadelphia for about 16 years.  The book itself was inspired by my time spent in the Kensington neighborhood of Philadelphia interviewing a lot of the people that I met there, both longtime residents of the neighborhood and also people who were transient,  a lot of people struggling with addiction and a lot of women doing sex work to fund their  physical addiction to opioids. You find out about their past,  their road into addiction, their aspirations, their fears.  I began to lead free writing workshops at an organization named St. Francis Inn, which is a longstanding food service organization in the community. They had a women's day shelter where I taught.  I was really able to connect with people within the community on a quite personal level and loved my experiences in Kensington. And I still go, I'm still quite close with a number of the community workers, people who run free healthcare clinics. All of it ultimately informed the writing of Long Bright River.
