I picked up this book because I want to understand the neuroscience behind reading. I want to know how it affects the brain and how we are damaging that by spending too much time on screens. The first part of the book did engage with this aspect, but it increasingly deviated into how to fix society and the damage caused to society by not ensuring we have enough deep readers from an early age. Unfortunately, the book is extremely American-centric so much of that part didn't really apply to my context (I live in India). I also don't think that the whole epistolary form works here. It's just a gimmick - it's not like these are really letters in any structural or literary sense of the form.
