Using extensive interviews and previously unexplored archival material Hayman examines the work of the Task Force on Federally Sentenced Women and assesses the opening of the first three prisons. She questions the notion that prisons can simultaneously "heal" and punish suggesting that the power of "the prison" inevitably triumphs over the good intentions of reformers.Imprisoning Our Sisters also looks at the disproportionate number of Aboriginal women prisoners. Hayman shows how the concept of a healing lodge has led to the integration of Aboriginal culture and spirituality into official penal discourse and contributed to wider reform during a period when Canadians were trying to provide a distinctive solution to the problem of imprisoned women.
