Celia Ghezzi is just 8 years old, but she already knows plenty about Harriet Tubman, Helen Keller and other important historical figures.
That's because she's been devouring the "Who Was?" series of historical books for children.
"I like them so much because you learn about the individual person," said Celia, a third-grader in Decatur, Georgia.
Jeremy Oppenzato of Brooklyn, New York, loved learning about knights and castles in Magic Tree House Fact Tracker No. 2, a nonfiction companion to the Magic Tree House historical fiction book "The Knight at Dawn."
"All the cool stuff that happened in the past, I think is fascinating," said Jeremy, age 7. "Like how kings had the protected castle wall and moat and drawbridge. ... I learned how knights got past moats."
Summer slump? There's no such thing among these new fans of history.
Whether it's the Roman Empire or Chinese history, the U.S Civil War, the history of scientific discovery or more recent civil rights battles, the new wave of children's historical nonfiction is attracting a younger audience to read more about real events.
