The 128-page novel will cost about $15. Top Shelf says of Lewis and the graphic novel’s artist, “Together, they bring to life one of our nation’s most historic moments, a period both shameful and inspiring, and a movement whose echoes will be heard for generations.”

Lewis’s office declined to comment on the promotion of the book.

March is due to hit store shelves in August, two weeks ahead of the 50th anniversary of the March on Washington.
