The Last Kids on Earth and the Nightmare King

The Last Kids on Earth and the Nightmare King is the fourth book in the The Last Kids on Earth series by Max Brallier. In this thrilling adventure, Jack and his friends face a new challenge that threatens their post-apocalyptic world. While they've been enjoying life in their mind-blowing tree fort, racing through town like characters in a real-life Mario Kart game, and battling zombies with their monster allies, Jack's world is shaken when they discover they may not be the last kids on Earth. This revelation is a mixed blessing—Jack wants to keep things exactly as they are, but his friends might not agree once they meet other survivors.

However, their fun takes a dangerous turn as they are hunted by the Nightmare King, a terrifying, ancient evil bent on destroying the Earth. With their usual mix of humor and action, Jack must find a way to prove that life in the monster-filled world they've made for themselves is perfect—even if an ancient force of darkness threatens everything. Blending text with black-and-white illustrations, this fast-paced book is perfect for readers who enjoy action, humor, and epic monster battles, all while navigating the complexities of friendship and survival in a post-apocalyptic world.
