This book is very easy to understand. It summarizes the life of Thomas Edison in a very compact space with very interesting language. In the middle of the book, there are pop questions and quick facts which make the book much better. I realised he made so many more inventions not just the light bulb.
*Spoiler Alert from below*
He invented the Phonograph, the first frame camera and many more.
It is pretty sad at last, all of america's light was dimmed for a minute as honor to a such great inventor.
