Better Angels: You Can Change the World. You Are Not Alone.

How can you take the worst thing that ever happened to you and use it to make thousands of children happy? Sadie Keller did just that. Told in her own words, this girl's inspiring story will stir the soul of anyone who wants to find hope in humanity. Diagnosed with cancer at age seven, Sadie sneaked into her mother's closet and filmed an instructional video to help kids like her. It became a viral sensation. Worried about whether Santa could deliver toys to all the kids in her hospital, she started a toy drive. It became a movement that turned into a foundation and a national year-round program that has collected tens of thousands of toys for kids battling cancer.
