Before Katniss Everdeen ever volunteered as tribute, there was Gregor. He was just an eleven-year-old kid from New York City stuck in a laundry room. Then he fell through a grate. Honestly, if you haven't read the Gregor the Overlander series, you’re missing out on the rawest middle-grade fantasy ever written. It’s weird to think the woman who defined the YA dystopian genre with The Hunger Games started out writing about giant cockroaches and rideable bats, but here we are. Suzanne Collins didn't hold back. Not even a little bit.
The Underdark isn't some whimsical Narnia. It’s a terrifying, subterranean war zone where death is permanent and the stakes are claustrophobic. You've got these pale, purple-eyed humans living in a stone city called Regalia, constantly on the verge of being wiped out by giant rats. It sounds like a Saturday morning cartoon until you actually start reading. Then you realize it's a gritty meditation on the cyclical nature of violence and the absolute horror of biological warfare.
What the Gregor the Overlander Series Gets Right About War
Most "chosen one" stories feel like a power fantasy. This isn't that. When Gregor becomes the "Warrior" of prophecy, he doesn't want it. He’s a kid trying to keep his toddler sister, Boots, safe while searching for his missing father. The brilliance of the Gregor the Overlander series lies in how Collins treats her young protagonist. She respects his trauma. She doesn't let him off the hook for the lives he takes, even when those lives belong to "monsters."
The rats, or "Gnawers," aren't just faceless villains. Characters like Ripred—a scarred, cynical rat who loves sushi and hates everyone—prove that the Underland is full of shades of gray. Ripred is easily one of the most complex mentors in fantasy literature. He’s mean. He’s manipulative. He’s also the only one telling the truth in a world built on propaganda.

War in these books has a cost. Characters you love die. They don't just "go away"; they perish in ways that stick with you. I still remember the shock of the first major death in The Overlander. It shifted the tone instantly. You realize the floor is gone. Anything can happen. Collins uses the Five Prophecies—written by the founder of Regalia, Bartholomew of Sandwich—not as a roadmap for glory, but as a countdown to tragedy.
The Complexity of the Underland Creatures
We need to talk about the "creepy crawlies." Most authors would make giant spiders and cockroaches one-dimensional. Collins makes them nations. The "Crawlers" (cockroaches) are pacifists who worship "The Princess" (Boots). It’s hilarious but also deeply touching. They are the most vulnerable people in the Underland. Then you have the "Spinners" (spiders), who are aloof, capitalistic, and terrifyingly efficient.
The bond between a human and their giant bat—called "Bonds"—isn't just a pet relationship. It’s a soul-binding contract. If one dies, the other is shattered. When Ares and Gregor bond under extreme, life-threatening circumstances, it’s not a moment of triumph. It’s a moment of necessity born from grief. That’s the core vibe of the Gregor the Overlander series: finding light in a place that has literally never seen the sun.

Why People Still Sleep on This Series
It's probably the giant bugs. People see a cover with a big beetle and think "oh, this is for eight-year-olds." Big mistake. By the time you get to Gregor and the Code of Claw, the fifth and final book, you're looking at a full-scale genocide plot. The series tackles plague, scorched-earth tactics, and the PTSD of a kid who has seen too much.
Many readers argue that The Hunger Games is more "mature," but the Gregor the Overlander series is arguably darker because the protagonist is younger and his family is more central to the danger. There is no arena. The whole world is the arena.
The Prophecy of Bane and Misunderstood Villains
In the second book, Gregor and the Prophecy of Bane, we’re introduced to the "Bane." Everyone thinks it’s a monster. A giant, white rat destined to destroy the humans. When Gregor actually finds the Bane, it’s a baby. A confused, white rat pup named Pearlpale.

This is where Collins shows her hand as a writer who cares about ethics. Gregor is told he has to kill this baby to save his people. He can't do it. The fallout from that choice ripples through the next three books. It’s a masterclass in showing how "destiny" is often just a tool used by politicians to justify cruelty.
Actionable Steps for New and Returning Readers
If you're looking to dive into the Underland or introduce it to someone else, here’s how to get the most out of the experience.
- Read them in order, no skipping. The overarching plot regarding the "Prophecy of Blood" and the "Prophecy of Gray" relies heavily on the political setup in the first two books. You’ll be lost if you jump straight to the action in book three.
- Pay attention to the "Warrior" rage. Gregor develops a physical sensation called "the twitch," which is essentially a battle trance. It’s a fascinating look at how adrenaline and survival instincts can be both a gift and a curse.
- Don't ignore the audiobooks. Paul Boehmer narrates the series, and his voice for Ripred is exactly the kind of gravelly, sarcastic tone you’d expect from a two-hundred-pound rat.
- Look for the parallels to real-world history. Collins often draws from historical conflicts. The Underland’s struggle for resources and territory mirrors real human history in ways that are great for discussion, especially regarding how "civilized" societies treat those they deem "vermin."
- Prepare for the ending. It’s not a "happily ever after" with a bow on top. It’s realistic. It’s somber. It’s a rare middle-grade ending that respects the reader enough to admit that some scars don't heal, even if the war is won.
The Gregor the Overlander series remains a landmark in children's literature precisely because it refuses to talk down to its audience. It understands that kids are capable of understanding complex morality, grief, and the weight of responsibility. If you want a story that stays with you long after the final page is turned, go back to the laundry room. Fall down the hole. Just make sure you bring a flashlight.
