im an american and had never heard of this book before so i had to look it up. it seems extremely impressive that someone would undertake such a breadth of american experiences through its entire history. however, i also saw a lot of criticism that matches what you described. ill give you the same advice id give anyone studying any history: no book is perfect. if you really want to know as much as you can, you’ll have to read a ton of books from a ton of different sources. plenty of people love criticizing america, its very easy to do, but most authors wont try to write with such the breadth that this guy has, due to it often including bias and poor sources. its an easy thing to do poorly. if you want a factual overview of american history, id go for a textbook. you can then deep dive into anything that interests you. if you are interested in varying perspectives, there are plenty of african american, native american, feminist, etc. books. you can look up plenty of different book lists online. just look up the author/book before you leave, as there are plenty of frauds. hope that helps! whats gotten you interested in american history?
