Their stepfather stopped pretending the moment he caught the scent of Kyle’s pheromones. His touches lingered. His stares burned. And then he told them exactly what he wanted: both of them, together, under him. They should have said no. They didn’t. Now Alpha Daddy has them exactly where he wants them: in his room, in his bed, on their knees. And they’re not just letting him take them. They’re begging for it.

Chiara Ravensworth is a witch—half Magickal, half Mundane. Her mother, a covert agent for the Council of Magickal Elders, lives in the shadows, while Chiara stays with her father in the ordinary world. Divorced but still in love, her parents’ strange balance mirrors Chiara’s own: caught between two realms, searching for where she truly belongs. Gideon Swan has no memory of his Magickal bloodline.

He hides from the world to protect it. Until Chiara appears at his door on a storm-torn evening—and something within him quiets for the first time. She’s the woman from his dreams. Bound by an ancient, rare bond—twin flames—their connection is both a gift and a curse. Together, they could become the greatest force for good the world has ever seen… or, as twin flames in history did, they destroy each other in the fire of their own making. While in the shadows, something dark and patient waits. It needs only one thing to rise: their union, so it could harness that flame for itself.

One touch was all it took to unravel everything. I felt his aura before I saw him— raw, possessive, undeniably alpha. “You shouldn't be here, hybrid.” Xavier's voice rumbled through me as his barrier shimmered behind me, a magic meant only for purebloods. Yet here I stood, Karenina Mason, half-wolf and half-spirit, clutching the sacred moonstone that had torn me from my path. His golden eyes traced the arrow wound on my arm, and suddenly he was too close— warm breath on my neck as he whispered, "You broke my barrier..." His lips brushed mine, transferring his aura in a forbidden bond that left my heart racing. "Now you belong to me.” But with Rylan searching for me and Nathan's dark magic closing in, how long can I resist the alpha who claims me as his reluctant mate?
