“You're my mate," Kyle whispered, his eyes flashing gold in the dim light. I stumbled backward. "That's impossible. We're about to be family." "I know. But the bond doesn't care about that." He's supposed to be her future stepbrother. In four weeks, their parents are moving in together, and Kyle will be family. Off-limits. Forbidden. The bond between them is instant. It's the kind of love that can't be ignored, can't be denied. When Kyle looks at her, Ella feels it in her bones, this is forever. This is fate. Except fate has never been crueler. How can they be together when being together means destroying their family? When every stolen glance across the dinner table is a secret they have to keep? When loving each other means breaking their parents' hearts? She has two mates. A Triad Bond. So rare, most wolves think it's just a myth. But it's real, and it's hers, and now Ella has an impossible choice to make. Kyle is her first bond, her strongest connection. Losing him could break them both. But loving him means hiding, lying, living in the shadows of their own family. Jason offers her something different. With him, there are no secrets. No forbidden touches. No family dinners where she has to pretend her heart doesn't belong to the boy sitting across from her. Jason can give her everything Kyle can't, a normal life, a real future, a love she doesn't have to hide. But choosing one mate means hurting the other.

I simply signed the mate bond rejection papers. I surrendered the Alpha I had loved for ten years to my sister. A few days later, Ivy caused a scene at the Pack Alliance Banquet, humiliating the Silvermoon Alpha's daughter. Once again, I stepped forward to take her place, enduring the pain of a disfiguring silver brand. Later, when they demanded I test the safety of the Wolf Spirit Regeneration Ritual with my own body for my sister, I accepted with a smile. My Beta parents, their eyes red-rimmed, told me I was finally being the older sister I was supposed to be. Even Ryker, who had always been so distant toward me, stood before the cellar. He gently stroked my cheek for the first time in ages and said softly, "Harper, don't be afraid. As soon as the trial is over, I'll take you to see the auroras at Moon Goddess Lake." But he didn't know that, regardless of the trial's outcome, he would never see me again. My wolf spirit was already fading. Nothing could save me. This time, when I closed my eyes, it would be forever.

You will pay for your sins," he growled, freezing me with fear. "Please!" “You think you can hate me just because you discovered you're more powerful? Having two useless wolves inside that shabby body won’t save you, sweetheart.”
