The Devil’s Trainer

He broke her heart. She trained a monster to break his bones. Serena caught her boyfriend in bed with her own sister. Instead of crying, she packed her bags and walked into the darkest corner of the underground fighting world. Her goal? To find a man terrifying enough to destroy her ex inside the MMA cage. Enter Kaelen. Known as "The Killer," he’s a massive, scarred underground fighter with a violent past and zero limits. Serena offers him a deal: Let me coach you, and together we will ruin the man who destroyed us both. As brutal training sessions lead to explosive physical tension, Kaelen’s cold heart begins to thaw. He transforms from a lone wolf into a dangerously obsessed protector. When her ex tries to fight dirty and the Russian mafia threatens her life, they quickly learn one fatal rule: Never look at Kaelen’s coach, and never, ever touch his woman. From gritty underground cages to the flashing lights of Las Vegas, watch this badass female lead and her lethal champion deliver the ultimate beatdown. Blood, revenge, and a romance that hits harder than a heavyweight knockout.
