"Imagine if one day, without warning, the entire human race turns against you. One minute, all is right with the world. The next, every person you meet becomes a bloodthirsty savage ... That's the terrifying reality for Cal, Brick and Daisy. Friends, family, even their parents, are out to get them. Their world has the Fury. It will not rest until they are dead. Cal and the other victims of the Fury - the ones who survive - manage to locate each other. But just when they think they have found a safe haven, a place to hide from the world, things get worse. Some of them begin to change. And as they uncover the terrifying, monumental powers they suddenly possess, they realise the Fury-infected 'ferals' are not the real problem. Their true enemy is a celestial being of pure destruction, whom the teens must kill. Because there is no choice: if this battle is lost, the consequence will be THE END OF EVERYTHING."--Back cover.
