With all her energy spent trying to keep a roof above her brother and sister's head, Gabbi doesn't get time to play much anymore. Her parent's divorce has forced her to grow up too fast, leaving her to assume responsibilities well beyond those of a normal seventeen-year-old. "Hooligan" Harvie Burnt-out MMA fighter who's lost it all. He had the fairy-tale life—the perfect woman and a son he adored. Until the day it was ripped away from him in the most violent of ways. Hooligan is content to live with his rage ... until an angry girl breaches a chink in the armour that protects his black heart. She's broken-hearted. His heart is dead and decayed inside his chest. She’s lost the ability to trust while he doesn't think life has anything left to offer. When neither believes in fairy tales, can the vicious world of MMA show them that they're wrong? That even the most f#cked-up deserve a happily-ever-after? Brawl is the first book in the Black Hearts MMA series by Kylie Hillman. This coming-of-age tale is about more than MMA. There's themes of hate, hope, and healing - featuring a barely legal girl, who's wise beyond her years, and a much older man, who might have found love in the last place he thought possible.

The last thing he needs is to babysit a damsel in distress, especially one with a mouth like hers. Zali Mitchell Gabbi's little sister likes to stir drama. Stunningly beautiful and snarky by nature, she's ready to emerge from her sister's shadow and strike out on her own—if only she could get rid of her self-appointed guardian. Jep Haynes He’s an asshole and not afraid to show it. Breaking the rules is his way of flipping the universe a middle finger for the shitty hand he was dealt. Except, the trail of women and betrayed friends he leaves in his wake are cold comfort when there’s no family left to care. When Hooligan demands that he keep Zali from getting herself into trouble in the city, Jep knows he's in for a hell of a fight. She's hell-bent on self-destruction and happy to take him down with her. It doesn't take long before he realises her bitch act is nothing but a cry for help, and that the man who cares about no one might be the only person capable of saving her.
