“And the night we met again,” I whisper, “my wolf recognized you.” Silence. “Recognized me how?” she asks carefully. My chest burns even as my pulse thunders in my ears. “As my mate.” The word falls between us like shattered glass. Avara laughs. “That’s not funny.” “I know.” “You’re my brother.” “I know.” I find myself inching closer… closer. “That’s impossible. This is sick.” “I know,” I say again, voice breaking now. “I fought it. Gods, I fought it. I tried to convince myself my instincts were wrong, that my wolf was broken, that I was losing my mind.” Her hands shake. “Stop.” “I can’t,” I say hoarsely. “Because every second I’m near you, it gets worse. Because my wolf wants to kneel at your feet and tear the world apart to protect you.” Avara stands abruptly, backing away until her spine hits the wall. “You’re lying.” “I wish I were.” …………………………… Fifteen years after vanishing from the Silvermoon pack, Kaeden Vane returns, older, lethal, and right on time at thirty-three, the age decreed by the Moon Goddess for succession, having spent years years amassing forbidden knowledge, mastering dangerous magic, and preparing to destroy his father, the man who murdered his mother in a bid for godhood.

When Olivia moves into her father’s house, she expects discomfort and distance—not the quiet pull she feels toward his son. Adrian is older, already in college, and careful in ways that make him seem unreachable. At first, he treats her like a responsibility, someone he needs to look out for. But closeness has a way of changing things. It begins with small moments. Lingering conversations late into the night. Shared laughter that feels too intimate. The way Adrian always seems to notice when Olivia is overwhelmed, the way his voice softens when he speaks to her. What starts as protection slowly becomes attention—and attention turns into something dangerously close to desire. Olivia feels it first. A flutter in her chest when he enters the room. The way her breath catches when their eyes meet for a second too long. Adrian feels it too, even as he fights it—pulling away one moment, drawn back the next. They never say the words. They don’t have to. Every look holds meaning. Every accidental brush of hands lingers longer than it should. The air between them grows thick with everything they refuse to admit. They know the line they’re standing on. They know crossing it would change everything. Yet the heart doesn’t care about rules. What grows between them is soft but consuming—tender, aching, and forbidden. A love born in restraint, made stronger by everything they deny themselves. When their secret is discovered, it shatters them both. Adrian is sent away without goodbye. Olivia is left behind, clutching memories that feel too precious and too painful to keep. Years later, Olivia has built the life she once dreamed of. But some feelings don’t burn fast and disappear. They smolder. They wait. And they never truly let go.

And when he chose her over me, marrying the girl who had always been his world, my heart shattered in ways I never thought possible. Then I found him. The one who makes me laugh, who makes the pain of heartbreak fade… but there’s a problem. He’s forbidden. Older, untouchable, and the brother of the man I once loved. I told myself it wasn’t serious. That I could keep my heart guarded. But as our connection grows, the walls I built begin to crumble. Now, I’m caught in a dangerous, irresistible pull—one I shouldn’t give in to, but can’t resist. Some loves are forbidden. Some desires are dangerous. And some hearts, once broken, refuse to stay silent.
