Beginning in Africa and ending in Europe, Incarceration Nations is a first-person odyssey through the prison systems of the world. Professor, journalist, and founder of the Prison-to-College-Pipeline program, Dreisinger looks into the human stories of incarcerated men and women and those who imprison them, creating a jarring, poignant view of a world to which most are denied access, and a rethinking of one of America's most far-reaching global exports: the modern prison complex.

From serving as a restorative justice facilitator in a notorious South African prison and working with genocide survivors in Rwanda, to launching a creative writing class in an overcrowded Ugandan prison and coordinating a drama workshop for women prisoners in Thailand, Dreisinger examines the world behind bars with equal parts empathy and intellect. She journeys to Jamaica to visit a prison music program, to Singapore to learn about approaches to prisoner reentry, to Australia to grapple with the bottom line of private prisons, to a federal supermax in Brazil to confront the horrors of solitary confinement, and finally to the so-called model prisons of Norway. Incarceration Nations concludes with climactic lessons about the past, present, and future of justice.
