That’s a great question. Thanks for asking! The first 2 episodes are background info, then each book gets an episode (the last 2 get 2 episodes) and the course ends with 2 wrap-up episodes. I go through each book pretty thoroughly — lots of spoilers! You can certainly do the course without re-reading the books, and get a lot out of it. But as someone who has read the Little House series many times over, I heartily recommend re-reading. They are a quick read. As I tell my college students, it’s not like you’re reading Aristotle! You can definitely read along with the course, watching the episode that corresponds to each book when you get to it. I’d love to hear what you end up deciding to do and how it goes!
