Ella is going on vacation with the whole class! All together on a small ship! They want to sail across the sea between lonely islands, go ashore wherever they like, and truly relax from school. But on board, there is also a survival specialist who tells them what to do. And even the teacher follows her advice! He knows, for example, that it's smarter to let the kids fish without hooks, because using hooks is far too dangerous. Not just for the fish, but also for those standing next to or behind them. Like the teacher, for instance. A children's book about friendship and solidarity - for everyone who loves to laugh until they cry while reading.
