This has some interesting advice, some exercises, and an understanding perspective. That being said, there are SO many issues that I can only give this 2 out of 5 stars.
1 - This is obviously self published. There is no professional publishing house information on the inside back cover and not even any professional bios at the end.
2 - This advertises itself as having two authors, but whenever the content refers to its writer, it says, "I believe in you" etc. This is extremely confusing. Who actually wrote this? If the authors switched chapters--so there's only ever a single author per chapter--then who wrote each chapter? Are Sarah Davis and Linda Hall even real people?
3 - There are rampant spacing, formatting, and grammar issues. No one ran this by a copyeditor or even reread it back to front before shoving it to print.
4 - It's not even 2 books! The whole 2 books in 1 merchandising line is a lie. Book 1 is supposed to be a book and Book 2 is supposed to be a workbook. What actually happens is the second "book" COPIES and PASTES all the content from Book 1 and then adds some exercise questions to try and pass itself off as a wholly separate thing. Come on, people with ADHD aren't THIS forgetful!! There is so much padding to bring the page count up that it's cringe.
This is a bad book. I cannot recommend it to anyone. Those dealing with ADHD deserve better. Please seek out ADHD book and workbooks elsewhere. I only give this 2 stars instead of 1 because I did find some of the content useful.
