Query: Great book

I've heard of this book all my life but decided to read it.Polyanna has this way of getting under even the most kermudgeonly individuals and changes their attitudes for the positive.When Polyanna suffers an accident and is laid up in the hosiptal her positive attitude has its worst test but >spoiler< she comes out of it and is just as good as before.
