One False Note / Gordon Korman / 174 pages

Second book in the 39 Clues series. Each book in the series is written by a different author but uses all of the same characters and plotline. Each of the authors in the series knows how to write books that will hook readers. One False Note uses information about Mozart and his sister to help solve a clue. There's plenty of action, despicable characters and sibling rivalry. I can see why these books are never on the shelf at the library!
