From Westerfeld, author of the hugely popular Uglies and Leviathan series, comes a novel-within-a-novel. Told in alternating chapters, it's the story of 18-year-old Darcy Patel who has just signed a contract to publish her novel and Lizzie Scofield, who escapes a terrorist attack by crossing into the afterworld and is actually the subject of Darcy's book. Over the course of a year, Darcy moves to New York, finishes her novel, faces critics, and falls in love. Lizzie's story is more explosive, but like Darcy, she too falls in love. When a new threat surfaces, Lizzie's special gifts may not be enough to protect those she cares about most.
