Children’s comedy is a harder trick than it looks, and the Kid Normal books are built on it. The premise sits in the name of the series: a superhero story whose hero is conspicuously normal, which is the joke and the heart of the thing at once.
Chris Smith belongs to the branch of children’s writing that never talks down. The comedy is quick, the plotting is proper adventure rather than filler between gags, and the emotional business is handled without a lecture. That balance is why books like these get re-listened to rather than finished once.
The Final Five is a closing chapter rather than an opening one, which says something in itself. This is writing that finishes what it starts and gives a young audience the satisfaction of a real ending.
