First the sickness rotted the adults' minds. Then their bodies. Now they stalk the streets of London, hunting human flesh. The Holloway crew are survivors. They've fought their way across the city and made it to the Natural History Museum alive—just barely. But the fight will never end while the Enemy lives, unless there's another way. . .
