Reaper.

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. Whatever has killed these people is spreading fast, and the task of eradicating it falls to youthful 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, spreads electronically, they realize that the information superhighway will become a killing field, with tens of millions dead, unless they can root Reaper out.
