My Russian wife would like to learn more about American history. She would prefer something easy and entertaining to read. Basically a book or book series that covers the majority of American history at least the big events throughout history that most Americans tend to learn about in school growing up.
I am guessing this will need to be more than one book but if there are some recommendations for a beginner that has great English but is still learning that would be very much appreciated. I would be ok sacrificing detail for entertainment as well if the writing is simply easier and more enjoyable to read.
So there's a great list here on the subreddit wiki of books about American history. Starting there is a good shout, though it is worth saying that most of those recommendations are period or subject-specific, and if you want a broad overview it may not have the best options.
I'll say that I love "These Truths" by Jill Lepore for a pretty up-to-date grand sweep of American history from pre-Colonial to modern-day (2018 anyway). It's also a very accessible book written for a non-academic audience. I'd highly recommend starting there and then delving into specific subjects/smaller periods of time after. Then the wiki list will become more useful.
Cheekily, I'll throw in a recommendation for John Jakes "Kent Family Chronicles" as an accessible way to get a rough view of American history through the lens of historical fiction. It's certainly not a series of history books, as they are fictional novels following a family through colonial times up to around 1900, but I found them an entertaining enough read. At least I did as a high school student like 25 years ago. I've no idea how well they hold up for representing actual history but you'd get the broad outlines of what happened. It looks like you can get the whole series of 8 books on Kindle for $35.
