Morgan Kenworthy—a Berkeley student studying abroad and a guest of the de Carduzacs, family friends who have a chateau in St. Émilion in France—uncovers a coup against the government of France.

As General Tolbert suspects she knows about the plots, Morgan’s life and the life of her lover, Alex, Joseph’s stepson, are in danger. Morgan tries to leave Europe for the US but is thwarted, and Alex is captured by the general’s thugs. Now the two must rely on their wits, and their friends, for survival until they can convince the French Government who the real criminals are…
