Helix

A deadly terror is loose in the city. No one can see it . . . No one can fight it . . . No one can stop it. It's so small, it's invisible. So powerful, it's brought a city to its knees . . . It's a new life form. And it lives to kill.
But it has an enemy - Dr. Alex Delfinar, a renowned medical expert, up against more than the killer virus. He's facing a city gone mad with looting and fear, an armed and frightened national guard, a nest of buck-passing politicos, and a crazed Palestinian who's secretly experimenting in a makeshift lab. And as a deadly clock ticks away . . . As all the pieces begin to fit like a perfect jigsaw puzzle on a tiny microscopic spiral . . . A city holds its breath and waits . . . Waits to know if it will live . . . or die.
