The best teacher in the whole world

A super funny story about Marie and Jack, who attend the best school in the whole world. One day, they get a new teacher. Mr. Frenkie loves his mustache, his smart suit, his white sneakers, and he thinks teachers are quite important. What he doesn't like is bullying.
Just before the summer holidays, Mr. Frenkie takes his class to a deserted island. It seems like a fun school trip, but it is also an experiment. What happens to children on an uninhabited island? Do they stop bullying? Unfortunately, something goes terribly wrong, making the night tense for the children. Luckily, Marie is the only one who hasn't handed in her mobile phone and has pen and paper with her.

A great book, full of humor and surprising developments. Also suitable for children who don't actually like reading that much, partly due to the many funny illustrations by Marja Meijer.
