The publishers of Pure are evidently hoping it will become the next Twilight. The post-apocalyptic young adult novel hasn't yet been released in America, and already the movie rights have been sold, and Twilight producer Karen Rosenfelt has been hired to take it to the big screen.
Pure, by American writer Julianna Baggott, certainly has similar elements to its bloodsucking predecessor. It's a dark yet hopeful tale about a group of good-looking but scarred teenagers who band together to fight off evil in a world of shadows (and fall in love in the process), though it has a good helping of political conspiracy that lends the plot more depth.
It's set in America in a nuclear winter of the near future, about a decade after "The Detonations" laid the world to waste. An elite community was given advance warning of the attacks (blamed on an unnamed enemy state) and allocated refuge in the Dome - an enclosed climate-controlled city impervious to radiation, where they can live until the Earth recovers enough to be repopulated.
Those left outside the Dome took the full brunt of the Detonations. The humans and animals who weren't killed were hideously disfigured - scarred and fused to whatever they had been clinging to. Mothers were fused to their children, those who huddled together were fused in a group. Others were fused to animals, machines, concrete, glass, the earth. Humans, animals and monsters were left to scrounge, or prey on each other, for survival in a world swirling with ash and dust.
When they reach the age of 16, survivors are drafted en masse into the OSR, an army controlled by a fascist dictatorship. The more able become troops. The less able become target practice. The OSR will occasionally declare a Death Spree, when survivors are encouraged to form groups to hunt and kill the weakest among them, ostensibly to lower demand on resources.
