The actual story books, yes, but I wasn't thrilled with the activity book. WhenI preferred to use SOTW as one of the spines with History Odyssey
We use it as a spine, I also use the activity book and really like the ideas put out there for me. It's on the younger side for my kids, so I add in older reading using http://classicalhouseoflearning.com/. And I add documentaries from Netflix.
I used to but not anymore. I prefer to do my own history. I found the main book to not have enough history. I wasn't impressed by it. We have learned so much more by using library books.
