“Why does everyone assume I need a tragic backstory to justify what I am?” Adrian said, strolling slowly toward me like he had all the time in the world. His eyes locked on mine as he continued, “Oh no, honey. It isn't because mummy dearest died giving birth to me. Or because dear old dad was too busy to tuck me in at night" He stopped when he was directly in front of me. So close that his tall frame was towering intimidatingly over me. I lifted my chin stubbornly to look him in the eye, refusing to cower. He smirked at that, his hand going to swipe a stray strand of hair from my face. “Some of us,” he murmured, “are not broken.” His eyes darkened. “Some of us are just simply… evil.” ~ I was dragged to the execution block in chains, accused of being a monster the world had erased. Then the Alpha's wolf claimed me as mate and forced him to halt the execution. In a world where hybrids were hunted to extinction, I was the last mistake left alive. The last thing Lucien Dreadmoor wanted was his mate being the single weapon that could completely wipe out wolves from existence. The bond tied us together anyway, trapping me in his keep, his rules, his control. He called it protection. I called it a cage. As war stirs at the borders and a vampire prince begins circling, whispers spread that my blood could start another war… or end it. The Alpha wants to break the bond. The Vampire wants to claim me. And somewhere between fate and freedom, I must decide which monster I am willing to stand beside… and which one I am willing to become.

I walked into that pack with one goal, catch a killer. Not fall for the one man I swore I’d never see again. Grayson. Alpha. Arrogant. Dangerous. The same man who hated me for years… and now looks at me like I belong to him. The second our eyes meet, something inside me ignites. The mate bond. A cruel, twisted joke from the universe. Because he’s a werewolf, I’m human, and this kind of bond is forbidden. But when he’s close, logic burns away. His scent seeps under my skin. His touch makes it impossible to breathe. And the way he growls my name… it’s a sin I crave more than air. We’re supposed to be enemies. Instead, we’re tangled in a fire that could ruin us both. The pack is dying. A killer lurks in the shadows. And the Alpha I hate might be the only one who can save me… or destroy me completely. I came to stop a monster. I didn’t expect to fall for one.
