As second in command, Katherine Ann Miles understands the responsibilities of her role as vice president. But when the president of the United States dies from a heart attack only eight months into his term, Katherine feels utterly unprepared to assume the highest office in the land. Yet the new president has little time to dwell on the battles raging with Congress and within her own marriage: Iran is making pointed, grave threats toward Israel, and she will have to employ all her skills and diplomacy to avert a major military conflict. But just as the crisis heats up, clues emerge, suggesting that her beloved predecessor was assassinated and whoever wanted him dead is out to get her as well closer than she realizes."
