A mysterious crystal. A suburban garage. And a gateway to an infinite, unforgiving multiverse. When Nestor, a sixty-year-old former military pilot, and Arthur, a brilliant young subterranean biologist, venture into an unmapped, collapsed gallery deep within Brazil’s PETAR caverns, they expect to find nothing more than damp limestone. Instead, they unearth an anomalous, blue-violet crystal that violates every known law of physics—emitting a cold radiance and manipulating local spacetime. Back in a quiet dead-end enclave in São Paulo, the duo transforms a modest garage into a clandestine quantum laboratory. Using high-purity aluminum, PTFE shielding, and raw engineering grit, they construct a resonant cavity capable of channeling negative mass and stabilizing traversable wormholes. But forcing open a doorway into parallel realities is only the beginning. Joined by Hélio, a crusty, retired electronics engineer with a talent for impossible circuits, the trio discovers that the multiverse is no peaceful utopia: • A desolate, radioactive wasteland where a single historical divergence swept civilization away. • A lush, primeval biosphere teeming with silicon-armored predators, hyperacute toxins, and alien biologies. • A breathtaking subterranean Nexus forged by ancient plasma entities who seeded the stars. As police scrutiny mounts, deadly mechanical failures strike, and survival hangs by a thread across the event horizon, three ordinary men must confront a terrifying truth: How far will they go to explore the unknown—and what price must be paid to protect a secret that could destroy humanity? Packed with hard scientific realism, pulse-pounding survival thriller action, and unforgettable character chemistry, Multiverse: The Source Frequency is an epic sci-fi adventure perfect for fans of Blake Crouch, Michael Crichton, and grounded interdimensional fiction.
