Truth be told, my last review wasn't entirely accurate. I told you I bought them for my son to read to his kids when he is starting his family. All true.
Initially though, I was working with a student who loves to read, and bought the last 2 box sets to reach book 28. My goal was to read to her as a reward for her behavior. It worked, but we never got into the crux of the series. It was nice to be able to meet both goals.
As a mom, I was always big on series and box sets. When we started reading Magic Treehouse, my goal was to find them all, and now I have. Now, although my son is in his early 20s, it still may be nice to read through the entire box set. Full disclosure, I do not have the informational books, just the fictional books in the series.
