Ben's great passion is computer games. However, when he reaches level 4 of his new game "The City of Children," something strange happens: what was supposed to happen only in the game suddenly becomes reality - all the adults disappear from the city! While most children and teenagers are immediately excited, Ben and his friends recognize the seriousness of the situation. Current themes - with high identification potential for young people! The literature project addresses the main topics of the book (city, computer, professions, social behavior, friendship, fire, first aid, water, organization, newspaper, zoo animals, cooking...) through reading-related and interdisciplinary tasks, allowing for an intensive engagement with the book.
