Heidi is sixteen, living on a huge estate. She can't get better than C's, can't make many friends, and doesn't think much of herself. Patrick is seventeen, from a working family, and lives to be a volunteer emergency worker.
While Heidi's parents are away, a 747 crashes into her estate. She makes her uncertain way toward the passengers, leaving her insecurities behind, simply to act. Patrick arrives first to wade through the carnage, while Darienne, a passenger, walks away unhurt.
Hundreds of workers arrive and the book follows several of them, always focusing on the three teenagers: Heidi, Patrick, and the beautiful but incredibly selfish Darienne.
Daniel, a fifteen-year old trapped in the wreckage, feels his anger toward his parents dissolve as he wonders if he'll walk again, or even live. But everyone forgets little five-year-old Teddie. Will she survive? Heidi and Patrick find unknown strengths within themselves as the suspense blazes forward.
