Esteria, the queen of the northern human kingdom, was finally getting married to the vampire prince of her dreams. What began as a treaty between their two kingdoms had blossomed into a courtship where she had truly fallen in love. Life was perfect until darkness cast its shadow over her happiness. Her beloved vampire betrayed her, delivering a fatal blow. With her last breath, she made a desperate deal with a Demon God. "You will have to become my mate to gain the power to exact your revenge," he whispered in her ear, sending a shock through her dying body. This Demon God was not only breathtakingly gorgeous and immensely powerful, but he was also dangerously seductive. Now, he was offering her a deal that promised both vengeance and peril. Esteria’s mind was a storm of grief and fury. Could she handle the Demon God’s insatiable desires and the deadly power that came with their pact? Or would she be consumed by the chaotic demands of this new, dark world? "I will kill both of them. I will draw their last breath with my sword and burn their bodies with my fury," she vowed, her determination as fierce as the hellfire she now wielded.

“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.

As Kael adjusts to buses, phones, and indoor plumbing, it becomes clear he isn’t the monster Noah expected. Bound by rules neither fully understands, their pact draws attention from forces far older and far more dangerous than either of them. With power that always comes at a cost and a past that refuses to stay buried, Noah must decide how much of himself he’s willing to lose to survive and whether some bargains were never meant to be broken.
