Award-winning author-illustrator Linda Ólafsdóttir’s I Dare! I Can! I Will! is a full-color picture book inspired by the Long Friday—a real event in Iceland that inspired women around the world to stand up, walk out, and march together for women’s rights.

Vera and Mamma are headed out for a march, but it’s not just any march. It’s October 24 in Reykjavík, and on this day in 1975, the women of Iceland took the day off, walked out of their homes and away from their jobs—as farmworkers, butchers, and fisherwomen; wives, daughters, and children—and marched to demand equality and change, chanting: “I dare! I can! I will!”

And they did, inspiring and empowering girls and women to make change, not just in their country, but all around the world, making feminist history.
