I don't expect a lot from a 155 pages $1 book, but this would be an embarrassment even if it was a blog post. It's full of misspellings and just feels like the author as thrown together her notes on the topic without reviewing the final result even once.
Most of the book seems to be bullet lists and excerpts from the web, links to videos on Youtube and links to scientific studies that are behind paywalls. Don't get me wrong, I do value an on-point excerpt of a complicated study with a reference to the original material. The ever-present "This study [link] shows" used in this book however is a bit poor.
