The idea had started three winters earlier, when the town's only bookshop closed and the nearest public library was a forty-minute bus ride away. Lena, a retired ferry mechanic, bought the container at an auction, cut a wide window into one side and fitted shelves made from old pallets.","At first she owned barely two hundred books, most of them donated by neighbours who were clearing out their attics. There were cookbooks with sticky pages, faded atlases and a whole box of detective novels by the same author. Lena did not mind. She believed that any book was better than an empty shelf, and she let people take whatever they wanted without filling in a form.","That rule lasted exactly one month. By the fifth Saturday, half the shelves were bare, so she introduced a simple system: bring one book, take one book. Visitors who had nothing to swap could borrow a single title and return it within two weeks. To her surprise, almost everyone followed the rule, and the collection grew instead of shrinking.","The fishermen became her most loyal readers. They worked long, quiet nights at sea and asked for thick paperbacks that could survive a little salt water. Children came for the comics and stayed for the reading corner, where Lena had placed a worn armchair and a small electric heater for the cold months.","Today the container holds more than three thousand books, and a group of volunteers keeps it open on Wednesdays as well. When people ask Lena why she started, she usually shrugs and says the harbour already had boats and fish. What it was missing was stories."],"questions":[{"q":"What was Lena's job before she retired?","a":["Ferry mechanic","Schoolteacher","Bookshop owner","Fisher"]},{"q":"What did Lena change after the
