3.5 actually. I've heard patrons recommend this to each other so I finally gave book 2 a try. I thought Molly Moon was a dog! (A Dog is on the cover of the first book.) No, no, that would be Petunia. At any rate, I did enjoy Molly and her escapades for the most part. I appreciated the little choices Molly made in dealing with the evil grown-ups in her path.
