The Cardboard Sword Tournament

About this book:

In a suburban garage that smells of glue and graphite, fourteen-year-old Ren folds corrugated cardboard into blades that shouldn't cut air—let alone slice plastic bottles from six inches away. When his latest creation hums with a resonance that has no business coming from paper, he and his best friend Leo dive deeper into the secret architecture of laminate and intent, building weapons that blur the line between craft and conjuring. But they aren't the only ones who've discovered that a perfect edge, forged from belief and precise geometry, can rewrite the rules of matter.

Then Maya steps out of the night—a girl wielding a saber of black poster board that moves like liquid shadow—and invites them to the Paperweight Qualifiers. Suddenly Ren's obsession isn't a solitary curiosity; it's an entry ticket to an underground tournament where cardboard cuts steel, imagination shapes reality, and the championship bracket leads to something far stranger than a trophy. From the first careful score of a utility knife to the final fold that decides a duel, every layer of this story is engineered for wonder.

*The Cardboard Sword Tournament* is a love letter to making things by hand, a thriller built on the physics of the impossible, and a coming-of-age tale where the sharpest weapon isn't the blade—it's the conviction that holds it together. If you've ever suspected that the ordinary world hides a cutting edge, this is the tournament you've been waiting to enter.
