The 39 Clues is unstoppable! The bestselling series returns with an adventure spanning four explosive books and a website that places readers right in the action.

Confidential until October 2013!

The Cahill family has a secret. For five hundred years, they have guarded the 39 Clues – thirty-nine ingredients in a serum that transforms whomever takes it into the most powerful person on earth. If the serum got into the wrong hands, the disaster would rock the world. So certain Cahills have always made it their mission to keep the serum safe, buried, locked away. Until now.

 

Thirteen-year-old Dan Cahill and his older sister, Amy, are the latest guardians of the Clues. They think they’ve done everything right, but a tiny mistake leads to catastrophe. The serum is missing and Dan and Amy have to get it back and stop who stole it . . . before it’s game over. For everyone.

my thoughts

Unstoppable is a continuation of 39 Clues stories.   Someone has created the serum and is using it to take over the world! 

This is a wonderful addition to the series.  Adventures of Amy and Dan Cahill continue.  They are joined by Nellie, Pony, Ian, Jake, Atticus and Jonah.   This is a wild ride of ups and downs.  If you like the series, this will be a welcome addition.

We give this book 5 ice cream cones.
