Underwhere Books in Order

The Underwhere books begin when Zeke, Stephanie, and their friend Hector discover that there is a whole world beneath the one they know. It is called Underwhere, and it is filled with strange creatures, goofy dangers, and problems that are much bigger than the kids expected.

Their most useful and least polite ally is Fitz, Hector’s sarcastic cat. Fitz has plenty to say about the children’s decisions, and he is usually nearby when a situation needs an extra dose of skepticism. Together, the group must navigate a place that is part fantasy kingdom, part underground maze, and part comic-book fever dream.

Things get weird below ground.

The central threat is the evil Underlord, who wants to take control of the human world. Zeke, Stephanie, Hector, and Fitz are hardly the obvious choice to stop him, but that is the point. They are ordinary kids pushed into an extraordinary situation, and each adventure asks them to be a little braver and more resourceful than before.

The books mix prose chapters with comic-book sections. That format fits the story’s fast, visual humor and gives readers a change of pace as the action moves from one bizarre encounter to another. The jokes are often broad, including plenty of playful wordplay around the series title, but the characters still face genuine risks.

Zeke is an important part of the ongoing story because Underwhere has a connection to his identity and role in that world. As the series continues, the children learn more about the Underlord’s plans and what they will have to do to stop them. The plot builds across the books, so this is a series best read in order.

Start with Prince of Underwhere.

That first adventure introduces the friends, Fitz, the underground world, and the threat that links the series. Pirates of Underwhere and Flyboy of Underwhere continue their struggle, while later stories expand the world with new foes and comic complications.

The tone is energetic, irreverent, and kid-friendly. Readers can expect secret worlds, reluctant heroics, talking animals, and cliffhanger-style action, with illustrations that make the fantasy feel close to a graphic novel. It is a good fit for children who like funny adventures but want more than a simple one-off quest.

Underwhere may be beneath everything, but it does not stay out of sight for long.
