The story takes place in a post-apocalyptic world where water has become a rare resource and the main character, a young girl named Lena, must navigate this new reality and find a way to survive. The book begins with Lena living in a small village surrounded by vast fields of wheat and corn, but with no access to clean water. She spends her days collecting rainwater and using it sparingly, but she knows that this is not a sustainable solution. One day, a group of travelers arrives in the village, led by a charismatic leader named Max, who claims to have found a way to purify water using a device he calls the "super-tournament. " Lena is skeptical at first, but as she learns more about the device and its potential to revolutionize the way people live, she becomes convinced of its value.
