Adam Eisenberg tells the story of female law enforcement pioneers in "A Different Shade of Blue." The stories of 50 women on the Seattle Police Department provide insights into the sexism, size differences, harassment and other challenges of breaking through the blue ceiling. Seattle was one of the first cities to hire female officers in 1912, and one of the first to put women on the street as equal beat cops in 1975. The book arrived in July 2009.
