“The Troubletwisters are back and the stakes are higher than they’ve ever been” in this fantasy adventure by the New York Times–bestselling authors! (School Library Journal)

Jack and Jaide Shield have defended themselves against The Evil before—but it’s never been as dangerous as this. It isn’t just the town of Portland that’s threatened, it’s the whole Earth . . . and certain dimensions beyond.

Their mission is clear: survive the storm that’s coming, and save the ones who are missing . . .
