Cahills Vs. Vespers

The Clue hunt is over, but Amy and Dan's adventures have just begun. Cahills across the globe have been kidnapped by a new enemy, the Vespers, and it's up to Amy and Dan to perform a dangerous ransom -- a race that will take them from the hidden tunnels of the Roman Coliseum to the ancient city of Timbuktu. If Amy and Dan can't stop the Vespers -- the whole world will pay.

After the mysterious Vespers kidnap a number of Cahills, they order Amy and Dan to steal a priceless painting in exchange for the hostages. The siblings then rush to Italy where they arrange a heist that rivals the most famous art thefts in history. There's just one problem-the painting they steal is a fake. With the clock ticking, Amy and Dan have to track down the real painting before one of the Cahill hostages is lost forever.

With more than 9 million copies in print and 1.3 million online users, The 39 Clues is a global phenomenon. The adventure continues in The 39 Clues: Cahills vs. Vespers, with six books, two card packs, and a powerhouse lineup of authors. The enemy is coming. Are you ready to save the world?
