She has written many biographies, true stories about people's lives. Some famous people she has written biographies about are Helen Keller, Annie Sullivan, Eleanor Roosevelt, and Golda Meir.
I liked this biography. It was a small chapter book that told the story of Alexander Graham Bell's life. My favorite part was that it really was like a story, rather than just information about his life thrown together. It would be a good biography for children to use and read because it's interesting and informative at the same time.
