The Intergalactics by Erik Jon Slangerup: A Fierce Sci-Fi Survival Story for Middle Grade Readers

Erik Jon Slangerup’s The Intergalactics opens with a joke that turns out to be a warning. “Of all the ways they'd tried to kill him on Base Lab 9, Brinx figured the closest HyperHelix might ever come to success was breakfast.” For a moment, the cafeteria’s unpleasant food makes the danger sound like a kid’s exaggeration. Then the story makes clear that HyperHelix really is putting Brinx and the other children in mortal peril.

Published by Aladdin on September 29, 2026, this middle grade science fantasy follows children whose bodies have been engineered with alien genes. Their creators test the abilities those mutations produce by forcing them into deadly challenges. The children who survive long enough earn a chance to leave Base Lab 9 for a larger settlement. Brinx, who has grown up inside this system, has little reason to expect a fair deal from the adults in charge.

A journey with teeth

Brinx and his closest friend, Jang, are among the children sent away from the base. Their passage to a supposedly better future ends in a crash on a hostile alien planet. The survivors have to make their way across unfamiliar terrain toward the city they were meant to reach, facing danger from the planet’s living things as well as the uncertainty of what awaits them there.

This isn’t a gentle wilderness tale in which the natural world provides a ready supply of shelter and food. Here, new plants and animals signal that the children may be in immediate danger. The reviewer describes the losses along the way as frequent, giving the journey a harsh, suspenseful rhythm. Readers who enjoy high stakes and vividly described peril will find plenty to hold their attention.

The group’s changing shape gives the action a human center. These children belong to different mutation groups, and suspicion separates them at first. As they travel together, their distinct abilities become sources of hope, and cooperation begins to replace distrust. Their relationships grow through shared necessity, but the friendships that emerge also challenge the categories adults have imposed on them.

Brinx’s determination to find Jang adds a personal thread to the group’s larger struggle. He believes his friend survived the crash, even when they aren’t together. That conviction gives the journey an emotional pull beyond the next escape or encounter: survival matters because Brinx wants to reunite with someone he loves.

What survival means

The reviewer sees the book’s game-like structure as a strength, especially for young readers who enjoy games. The story moves through pulses of action, with the children figuring out how to evade threats and make use of their abilities. That pattern can make the journey feel immediate and propulsive, while the group’s setbacks keep the danger from becoming an easy sequence of wins.

Underneath the peril, Slangerup’s premise raises a question that will resonate with middle grade readers: who gets to decide what a young person’s life is for? Brinx and his companions have been shaped by adults to serve adult purposes. As they learn more about the future prepared for them, the choice ahead becomes more than a matter of finding shelter. They must weigh a safer, narrower existence against the risks of trying to claim control of their lives.

The reviewer recommends the novel to sixth graders who like science fiction or fantasy and want a story on the fierce side. The book’s violent situations and frightening creatures make it a better fit for readers ready for sustained peril than for those seeking a gentler adventure. Parents and booksellers choosing for younger readers may want to consider that intensity alongside the appealing friendship and self-determination themes.

The reviewer also notes that the book’s fictional treatment of children being shaped to serve adults is far more extreme than most young readers’ real experiences. That heightened premise gives the story room to explore familiar feelings—being underestimated, sorted into categories or expected to follow a plan—without suggesting that the children’s circumstances are ordinary.

The review copy came from the publisher, and the reviewer read the novel in a single sitting during a flight. Even after two and a half weeks, the story remained vivid in the reviewer’s mind. That’s a useful recommendation for a book built around peril and momentum: its individual dangers linger, but so do Brinx’s friendships and the question at the heart of his journey. For young readers who want their science fantasy adventurous and a little frightening, The Intergalactics looks like a strong next read.
