Book excerpt: "Mary Dyer did hang as a flag..." Mary Dyer was the first woman executed in America for her religious beliefs, but her death started a revolution no one could stop. Mary Dyer, Friend of Freedom is the first children's book about this largely forgotten civil rights leader. It tells the true story of her courageous fight for religious freedom against some of the most powerful men in colonial America. Middle-grade readers are encouraged to learn how this humble Quaker inspired kings and governors on two continents and became an international civil rights hero.
