She breaks every rule. He lives by them. Together, they'll burn the world down. Aspen Kingsley is a weapon—sharp, deadly, and impossible to control. When she's transferred to the Elite Guard under legendary warrior Ryzen Thorne, it's not a promotion. It's a punishment for being too damn good at her job. Ryzen Thorne doesn't do chaos. As Drayton's Sergeant-At-Arms, he follows orders without question. So when he's commanded to retrieve a dangerous magical target, he expects his new trainee to fall in line. The target? A six-year-old girl. Aspen refuses. Ryzen insists. Their first mission together becomes a battle of wills that ignites something neither can ignore—a soul-deep bond that defies every rule they've ever known. When Aspen discovers the child is the legendary Germaine Key—a living portal capable of shattering the balance between realms—she goes rogue to protect her. Ryzen must choose: uphold the oath that's defined his existence, or follow the reckless witch who's showing him that some orders deserve to be broken. But their rebellion has awakened darker forces. Betrayal runs deeper than either imagined, and the phoenix warrior who's died and been reborn more times than he can count might finally have found something worth living for. If she doesn't get them both killed first. If you love the sisterhood of Charmed, the fated mates of From Blood and Ash, and the dark magic of A Discovery of Witches, the Kingsley sisters are waiting for you.
