Excerpt:

“You going through this marriage with me might as well be like you digging your own grave. Because the moment you start to want more from me, I will divorce you. And the moment you break your promise and try to fight me… I will ruin you and break you apart completely. Mercilessly. You will regret ever meeting this devil tonight.” His threat was given in the same soft but cold voice.

But Elle did not even flinch. Her gaze never faltered either. This man was ruthless, and she knew that clearly. His eyes that moment promised nightmares and darkness without any promise of respite.

But no matter what he says now, it would still not change her decision. She truly had no other choice.

“I understand now…” she said quietly, steeling herself. “Since you don't trust that I will keep my word, how about we do this? You prepare the divorce documents beforehand now and I'll sign it. That way, once you decide to divorce me in the future, the papers would already have been signed and there would be no way I can trouble you about it. You would just need to send it to the lawyers and have it notarized.”

A heavy silence reigned before his quiet disbelieving laugh broke the silence.

“I'm at a loss for words, Princess Izabelle.” He looked wickedly amused. But then he started nodding in approval. “Fine, princess. I will marry you.”

When Arran decides to become a mage, he quickly discovers that magic can be more dangerous than he had ever imagined. Soon, he finds himself hunted for powers he never knew he had.
