Have you ever heard of the expression, "The pen is mightier than the sword?" Nine-year-old Martha Bowling hasn't because she lives in 1775, but she sure can relate to it. Martha's uncle is Thomas Jefferson. That's right, the Thomas Jefferson, the one who wrote the Declaration of Independence. You would be right in thinking that in this story it is his pen, a writer's pen, which is mightier than the sword. But what you don't know is that there is a pen even mightier than Thomas Jefferson's pen. For generations before you were even born, an artist and her pen have been drawing the future.
