One day, the teacher says that, from now on, two plus two is five. Nearly everyone accepts the new maths. And other strange things happen too. Suddenly there’s a zebra in the class; she says her name is Ariane. Ozzie goes to buy a joke to impress Ziva, but can’t find one that he can afford. Noepy takes part in a demonstration against the abolition of crying. Ziva’s family take it in turns to have hiccups.
Eleven students from one class, all aged around ten, talk about something strange that they have seen or done. Their stories are usually funny or gently philosophical. The characters sometimes just don’t seem to care if things happen that are actually impossible. And why should they?
But these stories are not as innocent as they sound. Maximiliaan lies awake for nights on end, worrying about the new maths. He really doesn’t understand why no one is protesting. Until one day he sees it for himself: two plus two really does make five. This leaves the reader in a state of confusion. Hang on, that’s not right though, is it? Or is it?
