March On!, written and illustrated by sisters Lucy and Grace Lang, celebrates the history of American women's suffrage and the iconic 1915 New York City women's march, as told in rhyme by a grandmother to her granddaughter at bedtime.

Inspired by recent women's marches, sisters Lucy and Grace Lang's book for very young children honors the centennial of the passage of the 19th Amendment, which secured women's right to vote in the United States. As the world churns, all parents are striving to raise informed, courageous children, equipped to handle a changing and dangerous world in the most responsible and productive ways possible. March On! draws on the iconography of the women's march that started it all, the historic 1915 New York City women's march, highlighting the tremendous potential for collective activism, in rhyme, coupled with unique and diverse pictures to appeal to both children's imaginations and adults' familiarity with archetypal American imagery.

Lucy is a New York City-based lawyer, criminal justice reformer, and teacher.

Grace is an upstate New York-based artist and teacher.
