More than two million people are currently behind bars in the United States. Incarceration not only separates the imprisoned from their families and communities, it also exposes them to shocking levels of deprivation and abuse and subjects them to the arbitrary cruelties of the criminal justice system. Yet, as Nicole Fleetwood reveals, America's prisons are filled with art. Despite the isolation and degradation they experience, the incarcerated are driven to assert their humanity in the face of a system that dehumanizes them.

Based on interviews with currently and formerly incarcerated artists, prison visits, and the author's own family experiences with the penal system, Marking Time shows how the imprisoned turn ordinary objects into elaborate works of art. Working with meager supplies and in the harshest conditions - including solitary confinement - these artists find ways to resist the brutality and depravity that prisons engender. The impact of their art, Fleetwood observes, can be felt far beyond prison walls.

As the movement to transform the country's criminal justice system grows, art provides the imprisoned with a political voice. Their works testify to the economic and racial injustices that underpin American punishment and offer a new vision of freedom for the 21st century.
