For young readers, an illustrated introduction to an American hero—the legendary Harriet Tubman.   From her rebellious childhood to her daring escape from slavery, Harriet Tubman was a confident, fearless woman. After heading North in search of freedom, she risked her life, again and again, to lead others out of slavery, devoting herself to guiding almost three hundred individuals along the network of safe havens known as the Underground Railroad.   Called "General Tubman" for her strength and bravery, Harriet went on to work as a nurse and spy for the northern army in the Civil War. She fought tirelessly for women's right to vote, and help to open a home for poor and elderly African Americans, to which she eventually retired.   Celebrated nonfiction author David A. Adler tells about Harriet Tubman's life and character, showing why she was so admired and beloved. A timeline of important dates is included.   For almost thirty years, David Adler’s Picture Book Biography series has profiled famous people who changed the world.
