As someone who loves reading novels, I can't buy books directly. However, I can introduce you to some information about the book if you need it. Ice Fruit was a Japanese mystery novel about a high school girl, Euko Kano, and her good friend, Shinosuke, who were investigating a mysterious incident in the school. If you are interested in mystery novels, then the Ice Cream series might be a good choice for you. If you want to buy books in the mainland of China, you can go to major e-commerce platforms or physical bookstores to buy them. Some online bookstores might also provide books related to ice cream. Also, if you like Japanese literature, you can consider reading other versions of the Ice Fruit series such as Japanese light novels or manga.
