From New York Times bestselling author Ben Mezrich, a fast-paced techno-thriller about a biological virus that spreads electronically.

In Boston, nine lawyers on a conference call suddenly convulse with pain, turn chalk white, and die. In Vermont, a young woman watching her favorite sitcom meets the same grisly fate, as does a group of sewer workers in Washington, D.C. Whatever has killed these people is spreading fast, and the task of eradicating it falls to young virologist Samantha Craig and paramedic Nick Barnes, whose brilliant surgical career was ruined by a crippling hand injury.

When Nick and Samantha discover that the virus, named Reaper, is spread through TVs and PCs, they realize that the information superhighway will become a killing field, with tens of millions dead, unless they can root Reaper out.

Their search employs a dazzling array of real-life wizardry, from Mylar body paint to Stealth helicopters to CIA-bred swarms of insects. At the core of Reaper's madness, they find a suavely megalomaniacal, up-from-the-slums, high-tech billionaire, an icily ingenious hacker, and a high-powered cabal that will do anything to save the world from technology, even if that means annihilating the world.
