The novel is set in St. Petersburg’s metro. A squad of militants is sent to find out why strange lights have appeared on the side of Kronstadt. But their path runs along the surface—an area struck by radiation, teeming with dangers and mutants. And the mutants are far from the worst of them.
So what lies ahead? Will the road lead to light and salvation, or will the squad meet an inglorious death at the end of the journey? And what role will Gleb play in this story—the boy Taran brought with him at the very beginning of the journey, at the station near Moscow?
