At three in the morning, I was urgently called to an underground hospital in Verdanza to operate on the mafia Don's only son. But the man lying on the bed was my husband, the same man who had sworn before leaving that he was going on a business trip, promised he would drink less, and told me not to worry. Outside the operating room, a young woman clutched my sleeve and nearly broke down in tears. "Doctor, please save my fiancé! He got shot while protecting me. We can pay anything!" A well-dressed middle-aged woman quickly pulled her back. "Sylvia, calm down! Think about the baby." At that moment, I came to a horrifying realization. The man I had supported for ten years with my scalpel, the man I believed was bankrupt and drowning in debt… He was actually the heir to the biggest mafia family in Verdanza. And now, he had put himself in the ICU to protect another woman. I felt as though my heart had been ripped open. In our years together, we had once had a child. Back then, he had convinced me to terminate the pregnancy with the excuse that we were buried in debt and couldn't afford a baby. Yet now, another woman was carrying his child, surrounded by his family's protection and cherished like a priceless treasure. If that was how it was going to be, fine. After this surgery, everything Luca Colleone and I had together would be over. Ten years of history, wiped clean.

On the day I donated my kidney, I never thought my wife, Rebecca Tanner, would cut open her own heart and confess her regrets. After all, she had staged her own death in a bombing, all so she and Mason Sanders could test my loyalty. All she left me was two billion in gambling debt and a contract selling me into slavery. The creditor said they would leave her body in the grave and spare it from being fed to the hyenas. But to do that, I had to sign a contract with my blood and become their pet from then on. After that, I was locked in an iron cage beneath an underground fighting ring. By day, they chained me up and forced me to lick the blood from the winners' shoes. At night, they injected me with drugs and threw me into the fighting ring, turning me into a living toy for the wealthy to bet on. One broken rib doubled the stakes. One lost tooth added another ten thousand dollars. When I heard that my parents had been stripped and thrown into the mouth of a volcano alive, I broke completely. Covered in blood, I snapped the iron chain and rushed to the volcano. Instead, I found my "dead" wife gently lighting Mason's cigarette. Mason puffed out a ring of smoke and sneered. "We still have ten seconds left on the bet, Rebecca. You've lost."

When a young girl named **Emilia** moves to an isolated, fog-drenched city in search of a fresh start, she quickly discovers that something is terribly wrong. The streets echo with silence, residents vanish without a trace, and time itself begins to twist and collapse. As doors appear in places they shouldn’t, and her own reflection begins acting on its own, Emilia realizes she’s trapped in a place that is not just haunted — it’s alive. Each chapter peels back a new layer of horror: shadowy watchers, eerie apparitions, underground tunnels, and ghostly echoes of past inhabitants. But the real terror lies within — the city seems to feed on fear, loneliness, and the feeling of failure. It reflects Emilia’s own anxieties back at her, warping her reality into a trial of the soul. As she searches for meaning, and later for escape, Emilia uncovers the city’s sinister purpose: it traps those most vulnerable and forces them to confront their darkest selves. With the help of other survivors — some real, some echoes — she must navigate psychological mazes and make impossible choices to survive. But survival isn't enough. Emilia must transform — not by escaping her fear, but by embracing it. In doing so, she becomes something more than a victim of the city. She becomes a guide, a witness, and eventually, a keeper of the door. *Trapped in the Hollow City* is a suspenseful, haunting exploration of inner demons, resilience, and the eerie beauty of choosing to become — even when the world seems built to break you.
