This is brilliant learning material. If you've completed the corresponding lessons in Lingua Latina, you can read these little dialogues pretty much fluently. This is invaluable both as a way to cement what you've learned and to build serious confidence, and I don't know why other curricula don't have materials like this (other than the fact that it was probably difficult to craft).
The scenes aren't great literature, but that's not the point. In fact, I'd say the author did a good job of making these at least mildly clever and charming, and definitely lighter in tone than the actual textbook.
My biggest complaint is that the length of the pieces is a bit erratic, and at least one was long enough to be a lesson on its own. I just got extra practice that day, I suppose.
