Elliot Moore is a high school science teacher who quizzes his class one day about an article in the New York Times. It s about the sudden, mysterious disappearance of bees. Yet again Nature is doing something inexplicable, and whatever science has to say about it will be, in the end, only a theory. Scientists will bring out more theories, but no explanations, when a more urgent dilemma hits the planet. It begins in Central Park. Suddenly and inexplicably, the behavior of everyone in the park changes in a most bizarre and horrible way. Soon, the strange behavior spreads throughout the city and beyond. Elliot, his wife, Alma, and Jess, the young daughter of a friend, will only have theories to guide them where to run and where to hide. But theories may not be enough.
