Reality is broken-and only a twelve-year-old and his uncle's junkyard inventions can fix it.When Brian Matthews discovers a strange machine hidden in his Uncle Harold's shed, his world flips upside down. Harold, an eccentric scientist-turned-auto-mechanic, has built something impossible: the Quantum Viewer-a device that lets you watch alternate realities like flipping through TV channels.With his loyal (and frequently panicked) best friend Winch and his hilariously fearless little brother Greg, Brian explores bizarre versions of their world-some fun, some terrifying, all dangerously real. But watching can only take them so far.After the Viewer is destroyed, Harold unveils his greatest invention yet: DINA, a beat-up car modified for dimension-hopping. Now they're not just observing other realities-they're in them.From dystopian deserts to twisted hometowns, the team must dodge danger, face impossible choices, and figure out who they can trust across timelines. Because in the multiverse, every choice matters-and some versions of yourself... should never exist.The Quantum Mechanic is a fast-paced sci-fi adventure grounded in real principles of quantum physics-a thrilling, mind-bending journey that teaches courage, responsibility, and the power of critical thinking.Ideal for classroom discussion, this story blends scientific concepts with moral complexity, making it a valuable addition to any school or library collection.
