If you loved how Jack rigs up Big Mama, fortifies the treehouse HQ, and treats every run-in with Blarg or gargantuan beasts like a boss fight, you’ll click with Fisher’s trek across a ruined Earth. In The Boy at the End of the World, Fisher wakes alone in a shattered future and teams up with a chirpy survival robot and a stubborn mammoth, improvising gear and strategies the way Jack and Quint hack together gadgets. It keeps the same upbeat, can-do vibe amid wreckage—and the creature encounters feel like the monster-of-the-week scrapes Jack relishes.

You laughed at Jack’s nonstop one-liners, doodle-ready monster smack talk, and triumphant post-battle celebrations after outwitting Blarg. The Zombie Chasers matches that energy: Zack and friends sprint through suburbia, splattering slime, swapping jokes, and improvising ridiculous anti-zombie tactics—very much the spirit of Jack, Quint, June, and Dirk piling into Big Mama for a chaotic supply raid. It’s the same fast, funny zombie trouble, with the stakes high and the humor higher.

If Jack building a new family with June, Quint, Dirk, and even Rover hit you in the feels, you’ll love Percy pulling together Annabeth and Grover into a tight, trust-first team. In The Lightning Thief, every encounter with mythic monsters is less about solo heroics and more about friends covering each other—just like holding the line from the treehouse or pulling a last-second rescue in Big Mama. The camaraderie, jokes-in-danger, and we’ve-got-your-back spirit mirror Jack’s crew perfectly.

Miss the way Jack’s squad divides roles—Quint the brain, Dirk the brawler, June the scout—when facing monsters? The Screaming Staircase gives you Lucy, Lockwood, and George coordinating ghost-hunts with snappy banter and risky gambits. Their casework has the same high-energy, mission-based feel as Jack’s boss-battle quests, and the chemistry inside the team will remind you of those treehouse war councils before a daring run past zombies and gargantuans.

If you tore through Jack’s rapid-fire missions—chasing parts for Big Mama, rescuing June, and leveling up to face Blarg—Gregor’s plunge into the Underland delivers that same momentum. Gregor the Overlander hurls its hero into a world of oversized bats, rats, and spiders where every chapter is a new chase, duel, or escape. It’s the page-turning, set-piece-to-set-piece rush that feels like Jack’s video-game-y apocalypse, complete with clever tactics and gutsy last stands.
