39 Clues: One False Note-Korman

39 Clues: One False Note by Gordon Korman is the second book in the series. This story picks up with Dan, Amy and their au pair Nellie in Europe. The note reference in the title lets you know that music is the focus for their next clue, specifically the music of Wolfgang Amadeus Mozart. It is another well written adventure that keeps you looking over your shoulder for the next bad guy (or relative) as you try to help Dan and Amy fit the clues together. I like that mini history lessons that are woven into the stories as well. Did you notice the new author on this book? Book 3 is due out soon and it is also written by a different author. Interesting concept.
