Poison

In "a novel almost unparalleled for density and invention" (Horn Book), YA phenom Chris Wooding introduces an electrifying heroine...and an unforgettable story.

Poison has always been a willful, contrary girl, prone to being argumentative and stubborn. So when her sister is snatched by the mean-spirited faeries, she seeks out the Phaerie Lord to get her back.
But finding him isn't easy, and the quest leads Poison into a murderous world of intrigue, danger, and deadly storytelling. With only her wits and her friends to aid her, Poison must survive the attentions of the Phaerie Lord, rescue her sister, and thwart a plot that's beyond anything she (or the reader) can imagine. . . .
