Query: Good information, but difficult to read

This author has a good following among professional systems engineers. However, this book is torture to read. Mr. Grady's writing is at times convoluted and he uses too many words to make his points. The book layout is circa 1960 style. Long monotonous paragraphs with little to no whitespace furthers the torture of reading. The diagrams are complicated, with no color, and not explained well (and most don't stand on their own).If you can make it through this book, no doubt you will learn something. But why does it have to be such a difficult journey?
