“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. And the full moon is coming and time is running out. And Ella is about to learn that when you're bonded to two Alphas, love isn't about choosing the right person.
