Before the night of the winter solstice, Brigida had everything: a mother, a whole heart and a place in two worlds. But there is darkness between these worlds, and when the time comes to make an offering to the demon, Lady Rubina disappears... and Brigida suffers. Rubina's land is in danger. As a small region, it depends on Lady Ruby's diplomacy. But snow falls and she disappears without a trace. And Brigida becomes the main suspect along with her mothers. When the demon attacks and marks her, she decides that this happened to Lady Rubina as well. To defeat the demon before the mark reaches her heart and changes her, and to avoid her mothers and lord's confrontation with the village, she agrees to help Lady Ruby's son, Caspian, find her. But the search drags on, and more and more demons appear... and they are hungry... Brigida and Caspian hope to find Lady Rubina alive. If they succeed, they will be able to close the gap between the witches and the village, as well as save Ruby from her bloodthirsty neighbors, but the difficulties are many and time is limited.
