This is one kid's novel that everyone can enjoy. I consider it a MUST read book for it's cleverness and the power of it's characters. It's fun, educational and empowering.
First published in 1986, before the concept of going viral on the internet became a thing, we actually see a fabricated word- "Frindle" going virual- slowly but surely.
Frindle even has a satisfying plot twist. It's by far my favorite Andrew Clements book.
