For the first time in four decades, prison populations are declining and politicians have reached the consensus that mass imprisonment is no longer sustainable. At this unique moment in the history of corrections, the opportunity has emerged to discuss in meaningful ways how best to shape efforts to control crime and to intervene effectively with offenders. The American Prison: Imagining a Different Future, by Francis T. Cullen, Cheryl, Lero Johnson, and Mary K. Stohr, pulls together established correctional scholars to imagine what this prison future might entail. Each scholar uses his or her expertise to craft-in an accessible way for students to read-a blueprint for how to create a new penology along a particular theme. For example, one contributor writes about how to use existing research expertise to create a prison that is therapeutic and another provides insight on how to create a feminist prison. In the final chapter the editors pull together the lessons learned in a cohesive, comprehensive essay.
