My 4 year old and I have been trying out different chapter book series, and we both really liked this one. She got really into this book. I love that the girls who are the main characters are respectful & caring; I didn't once have to sensor or skip any parts/words. (I'm looking at you Junie B. Jones!) The girls used their brains to work together & solve problems and there was a sweet little lesson about judging people by their out word appearance. Can't wait to read more of this series with my daughter!
