But what if the green door next door turns out to be a portal to the Night Lands, from where unknown and creepy creatures can come to visit at any moment, pretending to be people? With the disappearance of his wife and children, Orlov is forced to cross someone else's threshold, setting off on an incredible journey through a colorless space of death, rot, sin and darkness, from where few have returned alive.
