Atticus Higginbottom is trapped in the Nonex with his mortal enemy Mistress Jane and the corrupt and powerful Mr. Chu. No one has ever escaped the Nonex before, but for Tick, Jane, or Mr. Chu to have any hope of surviving the dangerous and deadly realm, they will have to work together for the first time in their lives. And they must escape. An all-consuming void has opened up and is unleashing monsters throughout the Realities. All of reality is unraveling at the seams and Tick's friends and fellow Realitants are facing an epic war that could spell the end of the universe itself. Mister George has one last weapon at his disposal however—the mysterious and powerful Karma button. But using it might be even more dangerous than anyone imagined. The Void of Mist and Thunder is the fourth and final book in the 13th Reality series.
