Betrayed by her own family, stripped of everything, and pushed to the edge, Zoe Sterling has lived a life filled with pain and regret. But when fate grants her a miraculous second chance, she's determined to rewrite her story—and this time, no one is touching her son. Armed with deadly fighting skills, a fearless attitude, and a mother's unbreakable love, Zoe steps into the brutal world of underground boxing to build a better future for her little boy. But her unexpected rise catches the attention of Damian Blackwood, a powerful, dangerously charming club owner who isn't used to women challenging him—let alone knocking him down. As old enemies resurface, buried secrets threaten to unravel, and an undeniable attraction begins to spark, Zoe has one rule: mess with her all you want, but mess with her son, and you're getting knocked out.
