Gordon Korman

Gordon Korman

Janus branch. Intelligence indicates that Korman wrote his first book at only 12 years old. He’s gone on to write more than 65 novels, including the Everest trilogy and the On the Run series. Gordon’s latest hideout is rumored to be in Great Neck, New York.

Amy and Dan follow a lead hidden in the sheet music of composer Wolfgang Amadeus Mozart. They trace his life through Austria, but their relatives aren’t far behind. Barely escaping police and a violent explosion, the pair find themselves navigating the crowded canals of Venice. They must track down the Clue while avoiding rival Cahills, booby traps, and an angry mob in the Janus stronghold.
