Some memories can save the world. Others must be forgotten.Ishan Weaver remembers everything-every conversation, every mistake, every pattern. When a wedding-day caper exposes a backdoor in ArkLight, the world's flagship quantum-key network, Ishan is pulled into a quiet war between institutions that want to control memory and people trying to preserve it. With systems engineer Leah Stone, a standards-committee skeptic, and a coalition of auditors, researchers, and civic hackers, he follows a trail from boardrooms to black sites-then into a channel that seems to carry messages from downstream in time.As crises stack-Q-Day exposure, gene-drive sabotage, neural interface abuse, and supply-chain compromise-the team faces a brutal choice: accept limits that protect human dignity, or unlock a god-mode that may cost it. Quantum Ghosts blends credible pipes (verification, governance, audits) with audacious speculation about memory, consent, and what we owe the future.You'll enjoy this if you like: near-future technothrillers, institution-savvy SF, and the ethical puzzles .Themes: memory vs. forgetting, standards and power, informed consent, resilience over control, love under pressure.
