Chapter 1: The Trouble with Borrowed Things

The science lab smelled like copper and regret.

Zara Okafor-Chen stood in the doorway, trying hard not to watch as Principal Morrison examined the apparatus on the table — a tangle of brass tubes, copper coils, and what appeared to be a modified hot plate that was now permanently scorched black around the edges. The device sat on the table like an indictment, evidence of everything they'd done wrong.

"This," Principal Morrison said, choosing each word carefully, his voice carrying the weight of someone who had given this speech too many times before, "is not supposed to exist in my school."

Pepper Achebe, sitting in the hard plastic chair that faced the principal's desk in what she probably thought was an ironic turn of events, kicked her feet and tried hard to look innocent. The scuff marks on her shoes told a different story entirely — they'd come from climbing through the ventilation system to escape what everyone was now calling "the lab explosion." A small explosion, they all insisted. Mostly small.

"It was for the science fair," Pepper said, her voice carefully constructed to sound helpful and remorseful. Neither quality came naturally to her. "Zara said it would work."

Zara felt her face go hot, the heat of injustice burning through her cheeks. "I said it might work if you followed the instructions. The instructions that you didn't follow because you never follow instructions."

"You didn't follow them either," Pepper shot back, her tone sharpening. She sat forward, pulling her feet under her. "You got to chapter three of the manual and decided 'close enough.' I just took that ball and ran with it."

"You're eleven years old," Principal Morrison said, his voice achieving that particular timber that made every student in the school at the same time wonder if they were in trouble too. He pinched the bridge of his nose. Zara had seen her own parents do this exact thing multiple times. It was the universal gesture of an adult reaching their limit. "You cannot be modifying school equipment. You cannot be building experimental devices. You certainly cannot be—"

"Technically," Pepper interjected, and Zara wanted to throw something at her, "it's equipment we built ourselves. We just... Used some school supplies."

"Borrowed school supplies," Teo added from where he sat next to Zara, perfectly positioned to look like he wasn't actually involved in any of this. Unlike Pepper, Teo had perfected the art of being present while remaining innocent. He could walk into a room where chaos had just occurred and convince anyone that he'd been doing homework the entire time. "I was only here for moral support and linguistic consultation."

"You rewired the outlet," Principal Morrison said flatly, consulting the incident report on his desk. "You added a step-down transformer that wasn't part of the original device. You modified the power delivery system."

"Which was actually a safety improvement," Teo began, his voice smooth and reasonable, the kind of voice that could convince you that up was down if he put his mind to it. "The original specifications would have—"

"All three of you are banned from the science lab for the rest of the month," Principal Morrison said, and his tone made it clear this was not a negotiation point. "Your parents will be called. Today. This afternoon. And Pepper, this is your third incident this year."

Zara watched her best friend's expression shift — just barely, just for a moment. The defiance flickered, replaced by something that looked almost like shame, before Pepper schooled her features back into that expression of detached amusement. Pepper was the toughest person Zara knew, brave in a way that Zara could only admire from a distance. But even tough people felt things like consequences. They just didn't like to show it.

The three of them were ushered out of the office in silence, their sneakers squeaking slightly against the linoleum floor. Zara felt the weight of Principal Morrison's disappointment as they left. She had rarely let adults down before. She was usually the responsible one, the one who did her homework, who followed the rules, who made good choices. But in this case, her responsibility had only made things worse. She had allowed Pepper to build something dangerous, had overlooked important safety measures, had prioritized the project over proper procedure. The walk back to homeroom felt longer than the walk down, as if the hallway had stretched itself out specifically to make them suffer.

Once they were safely away from the office, hidden in the alcove by the water fountains where nobody went anymore, Pepper spoke first.

"I'm sorry," she murmured, and the words cost her something. "I know you were excited about the fuel cell experiment. I know you had the whole thing planned out perfectly."

"I'm sorry I told you it would work," Zara said back, and she meant it. "I should have checked the math twice. I should have built a simulation first. I should have been more careful."

"I should have actually read the instructions instead of just skimming them," Pepper admitted, kicking at the wall. "I was in a hurry because I wanted to get it finished before the science fair, and I figured that since you'd already checked the theory, I could just build it faster."

Teo, who had the gift of knowing exactly when a moment needed lightening, made an explosion sound effect with his mouth. "PWOOOOSH. That hot plate really committed to the bit though. Like it heard the assignment. 'I'm going to leave this world in the most dramatic way possible. I'm going to go out in a blaze of glory.'"

Despite everything — despite the principal's office and the phone call coming that afternoon and the month-long ban from the one place in the school that had felt like her own personal kingdom — Zara smiled. This was who they were. The three of them getting into trouble, apologizing sincerely, then getting into the next trouble before the first apology had fully dried on their lips. It was a cycle, and it was familiar, and it was safe.

But something else was happening that day, something vast and strange that would pull them away from school and Principal Morrison and burnt equipment forever. They couldn't know it yet, couldn't feel it in their bones the way they would later. But it was coming, moving like a shadow, like ink spreading through water.

The call came during lunch period, right when Pepper was in the cafeteria pushing food around her tray and Teo was explaining to someone why the school's new recycling initiative didn't make mathematical sense. Zara was in the library, hiding in the back corner near the horror section — her favorite place to disappear when she needed to think.

Ms. Chen appeared in the doorway of the library looking strange and urgent and not at all like the woman who worked in the school's front office dealing with permission slips and parent phone calls. Her face had that particular expression that only appeared when something significant had happened.

"Zara. Teo. Pepper. You need to come with me. Now. Don't ask questions, just come."

Zara's stomach dropped. This was punishment. This had to be punishment for the lab incident. Some additional consequence they hadn't anticipated. Had the principal escalated? Were they being expelled?

But Ms. Chen's expression wasn't angry. It was worried. It was frightened, which was somehow worse.

They found Teo in the cafeteria, where he managed to extricate himself from a crowd of seventh graders who had apparently been enjoying his explanation of recycling inefficiency. Pepper appeared from the art room covered in what looked like papier-mâché paste. They followed Ms. Chen back to the front office.

In the office, waiting with the kind of patience that suggested they'd been waiting for a while, were Teo's older sister Carmen (who was in eighth grade and had no reason to be pulled from class), along with Mr. Reyes, Teo's father, who was definitely supposed to be at his job downtown.

"What's happening?" Zara asked, and she could hear the fear creeping into her voice like water through a crack. "Are we expelled? Is someone hurt?"

Teo's dad looked at her with an expression that made Zara's anxiety spike into full alert mode. It was the expression of someone who had bad news and no good way to deliver it. "The library called," he said. "Your mother called, Zara. Ms. Chen got the call first. The Librarian called. There's a problem at the Athenaeum."

The word hung in the air like a bell that had just rung, making everything freeze.

The Athenaeum. The Library Between Worlds. The place where stories lived in physical form, where the rules of reality bent themselves around narratives and characters and plotlines. The place that shouldn't exist, that they could only access through a hidden door behind the art history section of the public library.

"The Mystery Wing," Carmen murmured, and she looked at Zara with an expression that was part warning and part apology. "It's going dark."

Here the opening ends.

Better together

All seven Storykeeper ebooksSeven middle-grade adventures, delivered together to your shelf.

The greatest detective in fiction just vanished. And the case he was solving? It's unraveling reality itself.

Zara, Teo, and Pepper enter Greywick — a rain-soaked noir city where everyone lies and nothing is what it seems. The legendary detective Ashworth has disappeared mid-investigation, and without him, the mystery at the heart of this world is tearing it apart at the seams.

The Storykeepers must follow the clues themselves. Teo's ability to talk to story characters becomes their secret weapon — until the characters start lying to him. And when the trail leads to a shocking truth, the Storykeepers realize something terrifying: the Redactor might not be entirely wrong.

What do you do when the villain has a point?

Perfect for fans of Percy Jackson, The Land of Stories, and Nevermoor.

Look inside.
