The night the Obsidian Fang slaughtered my family under a false charge of treason, I swore I would never bow to another Alpha. For five years, I survived in the shadow-drenched borderlands of Paraná as an outcast healer, concealing the volatile, unstable magic humming beneath my skin. Then he arrived at my door. Cassiano. The ruthless enforcer of the Obsidian Fang. The very wolf who held the executioner's blade over my father’s throat. He didn’t come to finish the job. A lethal, ancient curse is rotting his pack from the inside out, and my forbidden blood is the only antidote left in the world. Cassiano expected a submissive captive he could chain to a stone cell. Instead, he found a woman ready to burn his entire fortress to ash. Yet the moment our skin touches, a violent, inescapable shockwave shatters the air—a forced fated-bond neither of us asked for, and both of us despise. Every instinct screams at me to rip his throat out. Every instinct screams at him to cage me away from the world. As we are thrust into a treacherous alliance to hunt a high-ranking traitor hiding in the shadows, the boundary between my consuming hatred and his terrifying obsession blurs into a dangerous addiction. But Cassiano is harboring a devastating secret about that bloody night five years ago—a revelation that will either heal my shattered soul or ignite a vengeance absolute enough to burn the entire supernatural kingdom to the ground.

Catarina Valença made one mistake: she saved him. When nineteen-year-old Cata finds a dying wolf-man bleeding out on a deserted road in Santa Catarina, she should have walked away. Instead, she drags Bento Bortoluzzi to her family's abandoned farmhouse—and the moment he wakes, he speaks her name. A name he should never have known. Bento is packless, exiled, and haunted by a massacre he swears he didn't commit. He's spent seven years hiding from the supernatural world, and he has no intention of belonging to anyone ever again. Then Cata discovers the impossible: Bento is her fated mate. But their bond is wrong. Every touch sends Cata spiraling through Bento's memories—his exile, the murders, the betrayal. And Bento sees something in Cata that terrifies him: she has no wolf, no scent, no place in his world. Yet every wolf who comes near her loses control. When Bento's former pack arrives hunting him, Cata refuses to surrender the wolf who was never supposed to be hers. But the murders that destroyed Bento's life have started again—and this time, the killer isn't hunting wolves. They're hunting mates. Every victim bears the same strange mark Cata has dreamed about since childhood. The same mark now burning on her skin. As Cata develops abilities no human should possess, and Bento uncovers the conspiracy behind his exile, they realize the truth: their mating was forbidden for a reason. And someone powerful will slaughter them both to keep it that way. Because some bonds were never meant to survive.
