Cold Hearted Bastard

2021

A full-length gritty mafia romance that blurs the lines between right and wrong... and love and hate. He didn’t have a heart... but he wanted hers. All I knew about life was anger and violence. Pain and suffering. Kill or be killed. I was a “fixer” for the Ruin—a syndicate for the Bratva, Cosa Nostra, Cartel, and any other organized crime faction that dealt in the darker, crueler aspects of humanity. I was a free agent who was called upon to do things weaker men didn’t have the stomach for. And when you surround yourself with death for long enough, soon, you didn’t remember what it felt like to be alive. And then I saw her. She was a fragile little thing who tried to be strong. But I could tell she’d seen too much horror in the world, too much of the ugly within people. I should have stayed away. I’d only bring her farther down into the darkness. But for the first time in my life, I felt a stirring in my chest, this protectiveness and possessiveness toward another living person. And it was painful. It made me feel alive. Lina tried to hide how broken she was, but I was an old friend of being ruined. She held secrets I’d find out. Because for the first time in my miserable life, I wanted something for myself. I felt something more than apathy and indifference. I wanted to possess the innocence she clung to. I wanted to break it open and consume it for myself. I could look into her too trusting blue eyes and knew I’d maim for her. I’d kill for her. And that became our truth when her past finally came back for her when my present tried to destroy her. They thought they could take the one thing—the only thing—I’d ever wanted for myself. They were wrong. When I looked at her, I felt some of the monster that made me who I retreated back to my black soul. He’d never leave... but he’d share the space. For her. A complete standalone novel in the Underworld Kings series.

Reckless Heir

2022

From USA Today bestselling author Jenika Snow comes a new full-length standalone arranged marriage mafia romance set in the Underworld Kings world that blurs the lines between right and wrong. My father sold me off to a ruthless killer in the Russian mafia, an alliance between the Bratva and the Cosa Nostra. An arranged marriage where I’d be at the mercy of the man who’d no doubt see me as his property, where I was sure he’d be just as cruel and violent as every other Made Man I’d known in my life. Nikolai Petrov, known to be a sociopath and for killing anyone for the smallest infraction. And I'd be forever tied to him, an accessory he could use or dispose of any way he saw fit. And then I found myself painted red, my wedding dress stained in blood. A man dead by my husband's hands for simply touching my hair. I was terrified of the lengths Nikolai would go to get what he wanted… to keep me as his, but despite all of that I felt something far stronger, far more dangerous. Need. Want. Dark and depraved desire. And it was all for the man who said I was his. For better or worse.

Corruption

2022

A Dark Mafia Romance From USA Today bestselling author Jenika Snow comes a new full-length standalone dark mafia romance set in the Underworld Kings world. Even the beast could get the beauty… he just had to take her. Anastasia was a Russian mafia princess. I was unworthy to even look at her. But that didn’t stop a bond, a friendship to form between us. She was the only good and right thing in my painful, brutal life. She was the only one who could look at my bruises and wounds and see I wasn’t a total waste of space. But I was ripped away from her, thrust into the underground world of violence and fighting, molded and shaped to be the ultimate killing machine for the Bratva. And that's who I was now. Razoreniye. Ruin. Now, ten years later all of humanity had been stripped from me, all the emotion and empathy that I’d once felt taken away until I was nothing more than the beast who craved blood and had far too many kills tallied up. But they could never take her away from me. And so I followed her, watched her through her bedroom window, broke into her apartment, and held her as she slept. I wasn’t a good man. I was carved out from the very devil himself, and although I would ever be good enough for Anastasia, that didn’t mean I’d ever let anyone else have her. So when she was forced to marry another, I did the only thing that made sense. I took her in the middle of the night and kept her locked up until she realized she was mine and mine alone.

Little Bird

2022

From USA Today bestselling author Jenika Snow comes a new full-length standalone dark mafia romance set in the Underworld Kings world. The first time I met Dmitry Petrov, he was making a deal for my sister’s hand in marriage with his brother. I should have hated him for that alone, but when he stopped my father from hitting me, my young heart felt something new and wonderful for the first time. It was this incurable sensation that consumed me at his protection. But he was nearly fifteen years older than me, more dangerous than any man I’d ever met, and only saw me as his sister-in-law’s younger sibling. And when he was arrested and thrown into jail, five long years passed. I refused to give up the notion that one day he’d see me as a woman—a woman he wanted. So I wrote to him daily, confided in him, told him about what was going on in my life, what I hated and loved. I did this all in the hopes he’d write back, wishing he’d want me the way I wanted him. But year after year passed with no response. Until that changed. Until he wrote back. Dmitry was cruel and harsh, saying things that should have made me cry. Not make me want him more. I knew I was playing with fire, sending a criminal pictures of myself after my eighteenth birthday, thinking about him as I did private things alone in my room. But he was a virus deep inside of me, and there was no cure for what I had. And then my life completely changed when my brother tried to marry me off. I refused to be a pawn in the mafia world, and so my only option was to leave the only home I’d ever known. But when Dmitry’s released from prison, I came face-to-face with the Russian mafia leader everyone fears. And he made one thing very clear. I’m his. He’s taking me. And anyone who tries to stop him will die.

All the Dangerous Things

2024

He was a monster, a killer, the type of man my brothers kept me away from. Gio, my sister-in-law's brother and the head of the West Coast Cosa Nostra, was family and off-limits. Maybe that was why I was so drawn to him. Violence and death clung to him like he was born in the pits of hell, and he thrived on it. Despite everything, I started a relationship with the devil himself, and I fell in love. I had to keep it a secret, knowing my brothers would kill Gio if they found out. But when I discovered I was pregnant, hiding it was impossible. To make matters worse, Gio and my brothers found themselves entangled with a dangerous new syndicate. It was a situation that threatened to ignite chaos and conflict, involving everyone I cared about. Including my new forbidden lover and the baby we were bringing into this hell on earth.
