Dark fantasy book cover in the style of Sarah J. Maas ACOTAR. At the very TOP, small elegant series title in Russian Cyrillic reading "ХРОНИКИ БЕССМЕРТНЫХ ДВОРОВ" in refined thin serif. Just below it, author name in Russian Cyrillic "ЭЛИС НОКС" in elegant serif. Large centered ornate emblem of a translucent ghostly heart made of pale spectral mist, faintly glowing and ethereal, surrounded by wisps of phantom fog, drifting spirit-like tendrils and delicate silver filigree. Dark moody palette: deep midnight blue and dark violet background with ghostly pale-silver spectral glow. Intricate baroque border. At the bottom, luxurious gold-foil serif title in Russian Cyrillic reading "ДВОР ПРИЗРАЧНЫХ СЕРДЕЦ". Atmospheric, haunting, mysterious, premium fantasy novel cover, symmetrical composition, matte dark background, sharp focus, correct Russian Cyrillic spelling.
