When the internet collapsed, it took the world with it, leaving its digital ghosts behind - and they are hungry. Former photojournalist Katerina fled the overrun cities to the relative safety of her grandmother's village on the edge of a forest, where she lives a solitary life of herbal medicine and beekeeping.

When a wordless boy finds her in the marketplace with nothing but her name in his pocket, her curiosity won't allow her to turn him away. But haunting his arrival are rumours of harvest failure and a rampant digital disease stirring up the ghosts, and the mood in the village starts to sour.

Accused of witchcraft, Katerina and Stefan escape into the forest, searching for his missing father and the truth behind the disease. If there is a cure, Katerina alone might find it, but first she must find the courage to trust others - because the ghosts that follow her aren't just digital.
