In broad desert daylight, a mysterious platoon of soldiers evacuates the entire population of Sunrise Valley, Nevada. Minutes later, a huge bomb detonates a hundred feet above the ground and lays waste to homes, cars, and playgrounds: a town annihilated in an instant. The Russian supercriminal known as the Wolf claims responsibility for the blast. Alex Cross is on vacation in San Francisco with his girlfriend, Jamilla Hughes, when he gets the call. World leaders have just four days to prevent an unimaginable cataclysm. Racing down the hairpin turns of the Riviera in the most unforgettable finale James Patterson has ever written, he confronts the truth of the Wolf's identity, a revelation that even Cross himself may be unable to survive.
