The Missing (Troubletwisters #4)

The fourth installment of the thrilling middle-grade fantasy series from bestselling authors Garth Nix and Sean Williams.

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. The Wardens have devised a plan to get rid of The Evil once and for all. The only problem is that destroying The Evil may also mean abandoning some innocent people -- including one of the twins. The battle against The Evil is going to places it's never been -- places Jack and Jaide would have never even imagined possible. Their mission is clear: survive the storm that's coming, and save the ones who are missing.
