Autism is hard to understand for people who aren't on the autistic spectrum. People can learn what autism is like to a certain extent, and how autistic people act. It's also not difficult to understand what to expect from people with autism and how to compensate for it. This book explains all of that, but it goes far beyond those aspects.
In addition to understanding what autism is and how it affects people, this book explains how people with autism think, and does so better than other books on the subject. Children may be told what to expect from those with autism and how they may act, but this book can help children understand in a way that will allow them to understand the "how and why" in addition to the "what."
But this in not a book about autism. It's a book about Temple Grandin and her work. Although it tells the story from the perspective of how she thinks, it focuses on her accomplishments and why she was able to do things that "normal people" can't. She does not consider herself "normal" and doesn't think that's a bad thing at all.
The book also tells the story of an industry. It tells how virtually the entire cattle industry didn't and couldn't understand things from a cow's perspective. It shows how humane treatment not only benefits the cows but also benefits the owners and workers. It shows how cruelty is not necessary to increase profits, and how the opposite is true.
This is also the story of change. The industry changed its practices to a very large extent due to the advice, innovations and inventions of Temple Grandin. You will not only understand how she came to understand what needed to be done, but also why "normal" people were incapable of figuring out the problem or coming anywhere close to understanding how their actions affected the animals. Thanks to Temple Grandin, the beef industry is far more humane.
This biography is not by Temple Grandin, but about her. It's for an audience who may not be ready for her books such as Animals in Translation: Using the Mysteries of Autism to Decode Animal Behavior. Its style is simple enough for children in the later years of elementary school through junior high school, but can be educational even for adults.
In many senses the style is far too simple for adults to feel that the book was written with them in mind. Parts of it are compelling enough that children will enjoy reading it rather than seeing it as a mere learning tool. But it will also serve well for book report material. The content is important enough that I would encourage schools to include this as required reading at some point in the curriculum though. Children need to understand not only that others are different, but why they are different, how they think and why they think the way they do. It can take away the feeling that those with autism are simply weird and replace it with the notion that their behavior makes perfect sense. But most of all it will show children just how much a person can accomplish in life even if others are willing to write them off as too different to fit in.
