Publisher's Synopsis
Yuri - a young man from a backwater Russian town - wakes to find the doors to his crumbling apartment complex welded shut... from the inside.
Before anyone can make sense of it, something not from this world kills a postman stranded on the other side of the door. And when the town's old evacuation sirens begin to blare, Yuri and everyone else in the building realize an impenetrable door could be the least of their worries. In fact, it could be the only thing standing between them and the otherworldly creatures roaming the now deserted streets outside...
Someone in the building knows what's going on. Now, it's up to Yuri to figure out who it is, what they know, how these events are linked to their town's past, and how to lead everyone to safety - before the threats lurking outside find their way in.
