Mission Unstoppable

In eight days, Coke and Pepsi McDonald are going to turn thirteen.

Before then, they'll jump off a cliff, get trapped in the locked basement of their burning school, chased cross-country by murderous lunatics, left for dead in the pit of a sand dune, forced to decipher mysterious coded messages, thrown into a giant vat of SPAM, and visit the world's largest . . . ball of twine!

There's more, but if we told you here, we'd have to kill you.

Megapopular author Dan Gutman brings on the excitement with an action-packed new series that's nothing short of dynamite. Join Coke and Pep on their quest to uncover just what it means to be part of The Genius Files. . . if you dare!
