Sonic Underground Siblings Novels & Stories

As the Principessa of the Falcone family, I craved danger and absolute freedom. But on my ninety-ninth attempt to escape my arranged marriage, Vito Moretti finally caught me. My dangerously handsome betrothed cornered me at an underground racetrack. "No one walks away from me, Liliana," he smirked from his modified Mustang. "You're the first." With my weakness for dangerous men, I made a life or death wager. "Beat me on the track, and I'll marry you. Lose, and you get out of my life." Our engines roared as we tore along the cliffside road, its curves dangerously free of guardrails. Nearing the finish line, I took a turn too fast and hurtled toward the edge. But just inches from victory, Vito jerked his wheel. He slammed his car into mine, knocking me to safety as his own plunged into the icy bay below. I scrambled down the cliff, terrified, and dragged his bleeding body from the water. "I lost," he gasped, life fading from his eyes. "You're free." My heart shattered into a million dazzling pieces as tears streamed down my face. Startled by my reaction, Vito swore softly. "Don't cry. I'll tell our fathers the broken engagement was my choice. No one will dare lay a finger on you." I sobbed and pressed my lips to his. "To hell with the bet, Vito Moretti. I'm marrying you!"

In the VIP lounge of an underground casino, Maeve, the Falcone family's princess, had been plied with too much hard liquor. Fueled by alcohol, someone goaded her into revealing the most shameless thing she'd ever done to win over the Don. She swirled her glass, pointed at me dealing cards behind the table, and threw her head back with a laugh. "Seven years ago, when Declan was in a coma after a shootout, I took his private phone. And I deleted the distress message that bitch sent him. Every last trace of it. Then I replied in his name: You're a burden. Go die." "You'll never guess what happened next. That idiot stood outside the safe house all night in a downpour, like a stray dog. I almost died laughing…" The room erupted in crude laughter. Only the man enthroned at the head of the table remained silent. The crystal whiskey glass in his hand shattered with a sharp crack. Blood mixed with the amber liquor, trickling over the veins on the back of his hand before dripping onto the carpet. His murderous, bloodshot eyes were locked on me. I calmly dealt the last hole card in front of him and offered a clean, white silk handkerchief. "Don Declan, you should wipe your hand. Blood on the felt is bad luck." After all, some stains never wash out.

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."

Nelson Smith has been struggling for survival due to kidney failure. Without a transplant, he has less than four months to live. No one in his family matched after tests were done. Not even his siblings, parents or cousins, except for one person, Janice Capuno, his wife. Janice used to be the darling of a wealthy Dynasty, until she hid her identity and married the man she loves, Nelson Smith, against her parent's wishes. Instead of getting love, she was treated like a servant by her mother-in-law, mocked as a gold-digger by her sister in-law, but for her husband, his love towards her remained unshakable. He'd never ceased defending and protecting her from his family, that's why when the doctors confirmed her to be a match, she didn't hesitate to get herself cut open to save Nelson's life. **** There was barely thirty minutes to the surgery, and Janice was already in her hospital gown, waiting to get cut and her kidney given out to save her husband's life, when the reality of everything she had believed in came changing in her eyes. "Babe....my phone...switch it off...battery." Nelson pointed to his bag weakly before the sedative took full action on him. Just before she'll put the phone off, a WhatsApp notification suddenly popped up. It was from Tricia, his University ex-girlfriend. "Baby, has the fool gone into the theatre yet? I can't wait for this to be over. Once you get the kidney, we're done with her." The message read. Want to know what happened next?

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.

Fascinated by her boldness and the surge in his power when she offers herself, Casimir accepts her as his mate. But Casimir isn't the only wolf who wants Jesse. While Jesse cannot deny the sizzling chemistry between herself and Casimir, the King is emotionless and sometimes cruel. She's often drawn to the tender safety offered by a much less powerful wolf. A male Casimir would kill if he knew how deeply they connected. Will Casimir break Jesse just as he broke two mates before her? Will he discover her potentially deadly connection with another male? Or, will the smart and resourceful Jesse betray him and flee with the other wolf? Has the Wolf King finally met his match? #Domsub #dubcon #Taboo #contractmarriage #lovetriangle
