Mission Hurricane (The 39 Clues: Doublecross, Book 3)

EYE OF THE STORM

Thirteen-year-old Dan Cahill and his older sister, Amy, know that a disaster is about to strike the world. They know they are the only ones who can stop it, and they know they may already be too late. The person behind the disaster is their own relative, a man who calls himself the Outcast. He's already recreated two of history's worst disasters, and is only biding his time before he strikes again.The clues that the Cahill kids have gathered suggest that the Outcast's latest disaster is modeled after Hurricane Katrina. But what city will he target? And how can anyone conjure up a hurricane? Dan and Amy have no answers and very little time to find them. All they can count on is a tidal wave of trouble coming, and only them to stand in its way.
