My 4th grade class likes this series. Lots of puns with names regarding rodents and cheese. The author changes colors of the words and changes fonts way to much for me to not have a headache reading it. But what do I know, I'm an adult.
My first grade boy LOVES being read to from this series. The main character is a newspaper editor mouse who travels the world having exciting adventures. Adults will appreciate the Da Vinci Code spoof in this book. Some words in the text change color, shape, and size in accordance with their meaning - a nice touch for learning readers.
