I quite enjoyed reading this book. It had a lot of good information with Peanuts cartoons interspaced in between. It was published in 1980 so some of the information was a little outdated, and their prediction of us living on space colonies at the end was really far-fetched, but the information they had was still good.
It is laid out in a series of questions and answers and easy to read that way. Also the information built on itself in a logical fashion. It was a good book for children; informative, but not full of large, technical words.
