In the face of an alien threat, Russia and a xenophobic US must work together to save humanity in "one of the better science fiction novels of the year" (Library Journal).

In a near future where a paranoid America has sealed itself off from the rest of the world by a vast and complicated defense system, a young Russian scientist infiltrates all defenses to tell an almost unbelievable and truly terrifying story. At the outer reaches of the solar system, near Pluto, has been detected a superior form of intelligent life, far smarter than man and in possession of technology that makes it immune to attack from human weaponry and strong enough to easily destroy planet Earth. Can humans set aside their differences and mutual fears to work together and defeat a common enemy?
