It tells the story from Annie Sullivan's perspective. Annie, of course, was Helen Keller's teacher. It's mostly about how Annie got through to Helen, although bits of Annie's life are introduced.
I was really impressed how much Annie was able to accomplish in a short period of time, although I think a lot of her methods would be considered a bit harsh today!
Even though the book is for kids, I learned a lot about Annie and Helen.
I've been trying to get my daughter to read this book, but she's not interested, so my copy's up for grabs.
