“I know exactly who you are,” he murmured, his voice a low growl as he pressed me against the cold stone wall. His body caged mine, heat radiating from him like a wildfire waiting to consume.I lifted my chin, ignoring the way my pulse betrayed me. “Then you know why I’m here.”His lips brushed dangerously close to my ear, not touching—just enough to make my breath hitch. “Do you?” His fingers traced a slow, deliberate path down my arm, stopping just before my bound wrists. “Because you don’t look like a hunter right now.”I swallowed hard. “And you don’t look like a monster.”He chuckled, dark and amused. “Oh, little hunter, you have no idea”.
