Modern children are fascinated by phones, and the heroes of this book are no exception. Using a smartphone, they move to another reality. It all starts with the fact that nine-year-old Dasha’s older sister, a teenager, who spent all day on social networks and chats, disappears. It turned out that she ended up in a virtual world where there are the countries of Gamiya, Sotssetia, Tuktukgramia, Vidosia. Dasha and her friends go after her to bring her home. Not only fun adventures await them, but also difficult tests: challenges with food, participation in computer games, meeting with Fake and Like, an army of bots - and much more.
