In so many ways, forces unleashed in response to the Movement have come to dominate our politics, and technology is allowing the same injustices to be seen anew.

So March: Book One was the first book I ever wrote. And it was the most terrifying process I've ever been through.

What crystallized the importance of speaking out like that - of making nonviolence not just a tool or a tactic, but a way of life - was in San Diego [at Comic-Con]. One of the young girls who marched with us was wearing a hijab, and she came up to me afterward because I talked about my beard, and I talked about why I was doing it, and she came up and she gave me a hug, and she was crying. And she said, "Thank you. You have no idea how the other students treat me because they're shown that this is OK by Donald Trump. Thank you for speaking out."

It's important to realize that the series actually grows with the reader. "March: Book One" is a great introduction for kids as young as eight or nine years old. But then they grow with the reader. Book Two is bigger, Book Three is even bigger. And they grow more violent and more confrontational.

We're [also] trying to talk to a generation who grew up on the Internet. They're digital natives, and, essentially, they speak through sequential storytelling. I mean, a good comic-book panel is not that much different than a meme.

I think ['March'] is not just for the Black Lives Matter movement. It's for everyone. We all have to understand what happened then, so we can understand what's happening now.

I hope March is a guide for today's activists. It took raw courage for young people to volunteer to go to Mississippi in the summer of 1964, and unrelenting faith in the power of democracy to organize such a massive campaign.
