The 19th Amendment to the Constitution was ratified exactly 100 years ago Tuesday, the culmination of decades of activism that finally gave women the right to vote.

Finish the Fight! is a new children’s book that chronicles the stories of some of the lesser-known suffragettes that made the 19th Amendment possible. 

Greta talks with author Veronica Chambers about 100 years of women’s suffrage and some of her favorite, lesser-known suffragettes.
