Atomgrad-29

Grisha, lonely high school boy, moves into a top-secret experimental Russian military town as his family falls apart. He's surrounded by mutants and monsters in class, and the school building itself is trying to eliminate him. Even in his sleep he gets no rest; a handsome mystery man covered in prison tattoos pursues him, dragging him by force into deadly adventures in reality. Turns out the ultimate enemy was closer to them than either of them expected.
