Are you ready to save the world? The bestselling series returns with an adventure spanning 6 explosive books, 2 secret-filled card packs, and a website that places readers right in the action.

Thirteen-year-old Dan Cahill and his older sister, Amy, thought they belonged to the world's most powerful family. They thought the hunt for 39 Clues leading to the source of that power was over. They even thought they'd won. But Amy and Dan were wrong.

One by one, distress calls start coming in from around the globe. Cahills are being kidnapped by a shadowy group known only as the Vespers. Now Amy and Dan have only days to fulfill a bizarre ransom request or their captured friends will start dying. Amy and Dan don't know what the Vespers want or how to stop them. Only one thing is clear. The Vespers are playing to win, and if they get their hands on the Clues . . . the world will be their next hostage.

    I think this book is awesome!! I think this because this book has killings, adventure, and you feel like you're Amy or Dan Cahill which are the main characters.

      Although this was really good, the first series was still better.

          I can't believe that no one actually reviewed the book! It's excellent! It's the first book of the new 39 clues, only called Cahills vs. Vespers!
