Romance, humor, and fresh sea air: reading Janne Mommsen makes you happy! Jasmin is in her mid-thirties and lives in Cologne. Friends know that she used to be a happy person, but lately, she hasn't been the cheerful Rhinelander she once was. After a water pipe burst, she decides to travel to Föhr, a place she remembers from her teenage years. Back then, she was madly in love with a local islander. Perhaps that Sönke still lives there. However, instead of her first love, Jasmin meets a young man named Thore. He has recently become single and wants nothing more than to leave the island immediately. How convenient that Jasmin has already decided on the ferry to take a longer break: Jasmin and Thore simply swap apartments. He goes to Cologne, and she goes to Föhr. And thus begins the summer of their lives.
