Poisoned (Snow White, #1)

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 it and finding a cure. But uncovering the source of her kingdom's suffering is more dangerous than she could have ever imagined…both for herself and for everyone she loves.
