Landon Murphy and Jade Shu, stepsiblings turned wizard-like janitors, must step up after a disastrous encounter with the Locksmith—an immortal Auran who commands an army of Thingamajunks. With the Bureau of Educational Maintenance in disarray and their allies captured, Landon and Jade rally their friends from the School of Garbage and work to uncover vital clues hidden within the discarded trash of the magical landfill.

Their search leads them to the legendary Spencer Zumbro, who has been in hiding for six years. Spencer, burdened by guilt over the aging Auran boys under his care, is reluctantly drawn back into the fray when the villainous General Clean reemerges with a mysterious device that can turn Servites back into destructive Toxites. Meanwhile,
Landon undertakes a dangerous mission to go undercover and infiltrate the Thingamajunk army in hopes of sabotaging the Locksmith’s plans.

Faced with traps of living toilet paper, Glopified trash, and moral dilemmas, Landon and Jade must forge unlikely alliances and confront their fears to stop a Trashpocalypse that could destroy the entire world.

Brimming with humor, heart, and high-stakes action, War of the Wasteland is a thrilling tale of teamwork, redemption, and the power of hope in the dirtiest of battles.
