This book begins with a brief biography of Helen Keller, who lost both hearing and sight due to illness as a little girl. Helen did well because she could read and write. She was able to learn that by using Braille. Braille is a writing system that uses raised bumps on a page so that people can read by touch. The book includes the Braille alphabet, numbers, and punctuation symbols and challenges the reader to write their own name in Braille. A short biography of Louis Braille, the inventor of the Braille alphabet, is also included. This book also gives examples of well-known people who are blind and tools that help blind people be independent.
