Chasing Echoes

America is falling apart as the weaponized virus continues to rage unchecked through the country.  The governments in most cities have disintegrated, and the zombie-like infected are just one threat among many as citizens have to deal with roving gangs, power outages, and food shortages. Our disparate group of travellers just trying to get home—Disco, Jack, Leslie, and Matt—hardly know what to do with the top-secret information that just fell into their hands. What's worse—the discovery that their own government might have been involved in the development of the virus?  Or that to prevent that information from getting out, the U.S. government has dedicated all of its dwindling intelligence resources to the task of tracking down whoever has discovered their secrets...and killing them. It's a mad dash across the middle of America, and only the fate of the country is in the balance.
