In this spine-tingling follow-up to No Place for Monsters, which Diary of a Wimpy Kid author Jeff Kinney called "wildly imaginative and totally terrifying," a group of unlikely friends must save their school from the monsters that are threatening to destroy it.
After Levi and Kat defeated the Boojum and rescued their town's missing kids, they thought life would return to normal. But they're starting to wonder if there's ever been a "normal" in Cowslip Grove.
Overnight, hundreds of snowmen pop up all over town—and not the friendly, Frosty kind. When Willow warns Kat and Levi that something dangerous is coming—something hungry and relentless she calls The Harvest—they realize the Boojum is back. And it wants revenge.
But the Boojum underestimated who it would be facing. After a freak blizzard traps them inside their school and the Boojum hypnotizes their classmates, Kat and Levi assemble an army of monster hunters: Twila, Donte, Bug, and even their teacher, Ms. Padilla. They're all ready to fight.
The Harvest is coming. Will they survive?
