Poisonous mists settled in the lowlands 17 years ago, rendering ninety percent of the land uninhabitable and killing over half the population. Most blame their misfortune on industrialization or the fey, but some curse Snow White, the princess who was born poisoned.
As the only person who can survive entering the poisoned woods without a gas mask, Snow White has dedicated her life to studying the poison and finding a cure. This obsession draws her deeper into the woods and its secrets, where nothing is as it seems. When Snow White saves a man who should never have been saved, she unleashes an evil more horrifying and destructive than the poison.
