Are we idolizing the wicked or salvaging the strong?In BAD GIRLS, readers meet twenty-six of history’s most notorious women, each with a rotten reputation. But authors Jane Yolen and Heidi Stemple remind us that there are two sides to every story. Was Delilah a harlot or hero? Was Catherine the Great a great ruler, or just plain ruthless?
