About the book: 2023 / The System has come to the world... Although... Maybe not to the world. Maybe only to the territory of a separate hospital complex, where bloodthirsty zombies are roaming. A not too large group of people do not know about this, locked within the confines of this very complex. And to find out what’s going on outside, you just need to find a way out. But for Filin, it all started well: his last duty, followed by a well-deserved pension and a lake with a fishing rod, and not all that.
