Damn nation - Dark Horse

From the creator of UPN's Haunted and the Sci-Fi network original series Eureka comes one of the most ambitious and horrifying tales ever committed to the comics page! Writer Andrew Cosby has imagined a United States shut off from the world by concrete barricades and barbed wire - not because of what might get in, but what might get out. A vampire plague has spread from sea to shining sea and when a small holdout of scientists trapped outside of Buffalo, N.Y. discover a cure, it's up to a Special Ops team from the President's current offices in London to go in and get it.
