Kay Hamilton, the beautiful, fearless, and audacious DEA agent who went rogue in Rosarito Beach, has paid the price for her subversive behavior. As Viking Bay begins, Kay has been fired by the DEA and needs a job to support herself and her teenage daughter. Kay moves to Washington D.C. and connects with the Callahan Group, a shadowy quasi-governmental agency with an enigmatic agenda. For her first mission, Kay is told only a few facts: that the U.S. government wants Sahid Khan, a provincial Afghan governor, to become the nations next president, and that Khans daughter Araa Western-educated former party girlis her fathers key political advisor. Kay Hamilton is the perfect undercover operative to learn Aras secrets and sway her thinking in line with Americas interests. But when things go horribly wrong at a clandestine meeting in Afghanistan, Kay emerges at the center of an international plot that makes her question those she loves, those she works for, and her own faith in justice.
