This is a fascinating book. The commentary at the end, which includes letters and reports by Anne Sullivan enables you to read about this experience from the inside and the outside. I feel somehow as if I know Helen, despite the fact that she died long before I was born. She writes with a clarity and an intimacy and a warmth that draws you in to her feelings and experiences. I cannot even begin to imagine what it must be like to live without sight and sound. Helen's story is inspirational.
