By Holly Goddard Jones
The country's borders have receded behind a salt line--a ring of scorched earth that protects its citizens from deadly disease-carrying ticks. Few have any reason to venture out of zone, except for the adrenaline junkies who pay a fortune to tour what's left of nature. Those among the latest expedition include a popstar and his girlfriend, Edie; the tech giant Wes; and Marta, a seemingly simple housewife.
The group soon finds itself at the mercy of deadly ticks--and at the center of a murderous plot. They become captives in Ruby City, a community made up of outer-zone survivors determined to protect their hardscrabble existence. As alliances and friendships shift amongst the hostages, Edie, Wes, and Marta must decide how far they are willing to go to get to the right side of the Salt Line.
