“I didn’t just save your sister’s life, Elara. I bought yours. And I’m a man who expects a return on his investment.” Elara didn’t have options. Her sister was dying, the doctors had given up, and the only thing left in the house was an old grimoire and a ritual she was never supposed to touch. So she touched it. Now she belongs to Vane ,demon, Duke of the Seventh Circle, and the most terrifying man she has ever stood in front of. He doesn’t look like what she expected. He looks like someone who buys companies before breakfast and ruins people for sport. Cold, beautiful, and completely unbothered by the fact that he now owns her life. The deal was simple. Her sister lives. Elara obeys. Except the mark he burned into her skin doesn’t say owned. It says sacrifice. And the more time she spends inside his world , his rules, his house, his dangerous, suffocating presence ,the more she realises that Vane didn’t just answer her call that night. He’d been expecting it. She just doesn’t know why yet. And maybe that’s the most terrifying thing about him not the power, not the contract, not the way he looks at her like she’s something he’s been waiting centuries for. It’s that she’s starting to look back.
