The Echo Chamber

Every 24 hours, the universe resets. But the choices she made ten years ago are rewriting the laws of physics. Elena Vance was nobody—a night-shift cleaner at the world's most advanced quantum research facility. Until a freak accident near a classified particle accelerator tears open spacetime and sends her ten years into the past. At twenty-four again, Elena gets a chance to change the choices that once destroyed her life. But this is no ordinary time loop. Every midnight, reality shifts according to her choices, creating radically different worlds. A selfless decision can turn society into a dystopian nightmare. A selfish choice can warp gravity itself. Armed with her old notebooks, a stolen lab manual, and memories she can no longer trust, Elena must navigate increasingly unstable realities and solve the quantum puzzle hidden inside her past. Which version of her is real—and what happens when the universe erases the rest? The Echo Chamber is a mind-bending psychological sci-fi thriller about quantum reality, morality, identity, and the consequences of changing the past.
