Two last years Valentina spent in vain searches for paranormal phenomena. She came to the journalism as a person under big influence of pulp fiction and TV shows. Like a somebody who is ready to follow a revelation by the edge of Universe…at least she was thinking so. However Valentina chooses the hard career of reporter for “Era Nova” – a serious popular science magazine whose chief is poorly inclined to cheap sensation chasing. Two years ago, after graduating, Valentina expected success thinking about this job. She passionately wanted no glory, but the opportunity to head for the edge of the ordinary life, discovering something unknown and surprising.

Those two years have passed. Prospective sensations appear to be forgeries or ridiculous concurrences. Chief of “Era Nova” accepts her with less favourably. Fees start melting away as well as the possibility to see the other side of the ordinary world. Anyway, Valentina never surrenders. Her lively character became a little bit more venomous and she kept her passion for searching. She is still ready to go to the final frontier and explore what is hidden there – in the back of beyond…

The day destiny gives her a chance has come. Valentina gets a letter from woman who has found a strange room at her flat. There is no space in the building for this room. Our hero goes there and comes behind the border of the Hidden rooms’ world – a strange, unreal, illogical and… devilish attractive place. From this moment the journey begins and leads her far away from usual reality. Every new world Valentina gets into lives by its own rules, its own logic. But soon an outer danger connects to Hidden rooms’ puzzles. Valentina finds that a terrible murderer is on the chase. Evidences of his presence become clearer from one world to another.

Can Valentina gain advantage over her fears and the murderer or she will stay in Hidden rooms forever?
