Kira Aderka, the daughter of a wealthy merchant from the Forest Lands, is content with her quiet, steady life. But one day she is caught by a curse—and since then every night she falls into the Underworld, the realm of snakes and their terrifying enchantments. Without sleep and peace, Kira grows weaker and realizes her days are numbered. The only one who offers help is the mysterious dark sorcerer Dyu la Molnar. His methods are dangerous, his past is shrouded in darkness, but Kira has no choice. To break the bond with the Underworld, they set off on a journey through worlds where magic intertwines with lies, and every gain leads to a loss. A story of survival, the price of knowledge, and love—about how thin the line is between light and darkness. For whom is this book? For fans of dark, atmospheric fantasy where mythology is woven with poetic language. For those captivated by Slavic and Balkan folklore. For lovers of beautiful prose, complex characters, and genre blending—from mysticism to a parable.
