The subtitle for this work is:  How Sandra Day O’Connor and Ruth Bader Ginsburg Went to the Supreme Court and Changed the World.  Another subtitle that would have been as appropriate is:  How Far Females Have Come in The United States in the Last 60 Years.  Using court cases as well as the personal experiences of O’Connor and Ginsburg, Hirshman illustrates the evolving role and the discrimination women have faced since the mid 1950’s.  To get to where we are today has been a slow, incremental process.

Sisters in Law also gives biographies of two Supreme Court Justices with very different backgrounds, philosophies and political views who still managed to respect each other and work well together.
