Prašina is a mysterious place: a dark island in the middle of glowing Prague. No one knows why, but electricity does not work in here: they do not turn on the lamps, the tramlines stop and the mobile phones have no signal.
In this creepy neighbourhood, two boys and a girl are searching for an ancient mystery that could change the world. An extraordinarily exciting story familiar to Jaroslav Foglar's style.
Vojtěch Matocha wrote a book that follows the successful tradition of the Czech Adventure Literature for the Youth and has put the story in the backdrop of contemporary Prague.
