Two teens find a mysterious monocle that bends reality—but they’re not the only ones after it. Secrets, danger, and adventure await!

Some books hook you with action, others with mystery. The Monocle by Mark Cavanagh grabs you with pure wonder—that feeling of being a kid again, discovering something strange and incredible, and knowing that nothing will ever be the same. This YA adventure delivers a thrilling mix of nostalgia, mystery, and mind-bending science fiction, making it a must-read for fans of Stranger Things, A Wrinkle in Time, and The Goonies.

The Monocle is a coming-of-age adventure with a twist. Mick Sullivan and Viv Oulette, two curious and fearless teens, stumble upon an alien artifact—a mysterious monocle hidden inside a metallic clam-shaped shell. At first, it seems like a weird trinket. Still, when they unlock its abilities—seeing other dimensions, teleportation, even weaponized energy beams—it quickly becomes apparent that they’ve found something way bigger than themselves. And they’re not the only ones interested. Enter Agent Flanders, a shadowy government official who wants the monocle for his own agenda, and suddenly, Mick and Viv are in a game much bigger (and far more dangerous) than they ever imagined.

What makes this book shine? For starters, Mick and Viv are fantastic protagonists. Their friendship feels genuine, fun, and full of personality—Their sharp, witty, and natural dialogue makes them feel like real teens rather than just “characters in a book.” The Monocle is also an intriguing mystery. It slowly unravels the secrets of the monocle, blending sci-fi elements with a classic small-town adventure feel. Every discovery brings more questions, making it impossible to put down.

Mark Cavanagh has also given us a really strong sci-fi concept. The monocle itself isn’t just a gimmick—it’s an artifact with fascinating, reality-bending properties, and how the book explores its power is genuinely exciting. The blend of hard and soft sci-fi elements makes it feel both grounded and fantastical at the same time. I also loved the tense government conspiracy angle. It’s not just a story about cool powers—there’s a sense that something massive is at play, and Mick and Viv are in way over their heads.

The Monocle is a wildly fun, smart, and exciting YA sci-fi adventure that blends mystery, government intrigue, and coming-of-age friendship perfectly. If you love books that capture that nostalgic sense of discovery while keeping you on the edge of your seat, this one’s for you. A great YA read for young and old alike!

If you love epic fantasy with detailed world-building and character-driven conflicts, this book is for you. Fans of The Magicians, The Inheritance Cycle, or The Belgariad—especially those who enjoy magic academies and slow-burning dark transformations—will find a lot to appreciate. Would I read the sequel? Definitely!
