It has some charts and graphs and they don't always work well when the text is read on a Kindle, how I'm reading/consuming the book. If I'm not looking at it, I won't know that I've missed a table/chart or how it's supposed to be read. There was one table where it had a title on top of three(?) columns, but it reads better if you either read the words straight down instead of across, and you can't tell when they shift to a new column to another or how the words are connected or switch to another set. It also has some worksheets/questions because it's partly explaining what is and letting people see if they have similar issues/traits/behaviors...not quite sure of the term.
Lots of thinking, not just reading. Does that help?
[Yes, I would recommend it, but I probably wouldn't buy it. It's a library book. Once through may be enough. IF I wanted to keep it, I might order a print copy.]
