This is such an incredibly cute collection of stories. I read these aloud to my 9 year old son, and while some of the vocabulary was above his grade level, he understood it very well. I loved that this collection included some classic re-tellings of classics (The Emperor's New Clothes) and some modern/ethnic re-tellings of classics (Cinderella).
As a HS English teacher, I'm a bit confused as to where this could be used in a school setting--the writing seems to be at an upper middle to high school level, where we don't really read stories out loud to students anymore. If I could read to my high school students, this would be my go-to pick.
