Boris Yamshchik, a writer working in the genre of “horror literature,” once says: “My light, mirror! Tell me...” and the mirror answers him. From this moment, the Coachman's life takes a sharp turn. The reflection behaves in the most unpleasant way, turning the life of the original into a nightmare. The Coachman's loved ones are under threat, some have been seriously injured, and we urgently need to find a way to tame the nasty double. Will the Coachman be able to cope with the reflection that has plans for his master - or will resistance only worsen an already bad situation? In the new novel by G. L. Oldie, as in a mirror, the dark and light corners of the human soul are reflected, and at times the light changes places with darkness.
