"I don't know how our boat trip will end. Everything is open. But now and here, Jonas doesn't steal and doesn't take drugs either. He can pull a hundred times at the wrong end of the lead." The single mother Franziska Krafft is no longer stoppable: she wants to get her drug-addicted 16-year-old son Jonas, who has slipped into crime, from the retreat clinic on her sailboat. Heaven and hell sets her in motion for this idea, talks her mouth fuzzy at the youth office until it finally says: Jonas can spend the summer on the boat with her and his brothers. But how is everyday life on board when mother and son had hardly any contact for three years? Will Jonas persevere without drugs? And does the teen crew get along on the stormy North Sea? A captivating book that shows what powers a mother mobilizes when it comes to her child's life.
