Nancy's European summer is getting hot. First stop: Romance. Destination: Danger!

Nancy, Bess, and George are off on a continental adventure into the gorgeous heart of Europe: -- Switzerland. And gorgeous is just the word for jet-setter Franz Haussman, who invites the girls out for a night of dancing at a chic club -- on the shores of Lake Geneva. But before the music ends, the mystery begins . and Franz's life hangs in the balance!

Soon after Franz receives a death threat, Nancy finds herself in the eye of an Alpine storm of romantic intrigue, family scandal, and big-business blackmail. Nancy's summer abroad is just getting started, but Franz draws her into a world of jealousy, ambition, and greed as dark and twisting as the medieval streets of old-town Geneva.
