On any given day in America, over 80,000 people are held in solitary confinement—held in utter isolation for twenty-three or twenty-four hours a day, moved there from the general population without any legal process or justification. In a "potent cry of anguish from men and women buried way down in the hole" ( ), offers rare accounts from the people who are now or have been in solitary confinement. As Chelsea Manning wrote from her own solitary confinement cell, "The personal accounts by prisoners are some of the most disturbing that I have ever read." These firsthand accounts are supplemented by the writing of noted experts exploring the psychological, legal, ethical, and political dimensions of solitary confinement, and a comprehensive introduction by Solitary Watch co-founders James Ridgeway and Jean Casella. Sarah Shourd, herself a survivor of more than a year of solitary confinement, writes eloquently in a preface about an experience that changed her life.
