The Burmese python, one of the largest, most powerful snakes in the world, has established a breeding population in Florida's Everglades—and soon, the snakes will be poised to spread to other areas in the United States. How far will they get?

Biologists are plotting a counteroffensive, even as they're still making discoveries about the basic biology of these massive serpents. The scientists waging this "python war" have one objective: to preserve the ecological balance of the Everglades. Can they protect Florida's native species by stopping the pythons, or is it already too late?
