A massive ancient linden tree on a hill, its dark, deeply furrowed bark forming a faint human face — two deep hollows for eyes, a long horizontal slit for a mouth. The tree stands beside a small dark wooden Orthodox church with a tented roof, silhouetted against a low gray autumn sky. A faint greenish glow pulses from within the bark. At the base, pale root-like tendrils curl across the ground. September, muted golden grass, fog rolling in. Painterly dark folk horror style, muted palette of charcoal, dark green, amber and bone-white. Atmospheric, ominous, quiet dread. Book cover composition, vertical.
