Ruthless Vows

To escape a gilded cage, I made a deal with the devil. Now he wants to own my soul.

Princess Jacqueline Marquet is out of time. With her royal family forcing her into a marriage with a vile Duke, she devises a desperate plan: a fake engagement to the one man she can control.

Enter Logan Dupont. The disgraced billionaire playboy. The charming, harmless, and utterly useless heir who is the perfect prop for her rebellion. My puppet.

But Logan is no one’s puppet.

He’s a ruthless, morally grey CEO with an obsession, and I’ve just handed him the keys to my kingdom. My carefully crafted contract becomes his terms. My safe-house becomes his penthouse. The man I hired to be my shield is a possessive alpha who intends to turn our fake relationship into an unbreakable reality.

He’s not the man I thought he was. He’s the man from that one-night stand in Geneva I swore to forget—a man who is possessive, dominant, and dangerously competent.

When enemies from my past threaten my life, Logan’s protection is swift, absolute, and terrifying. He’ll burn the world to the ground to keep me safe, proving his “touch her and you die” promise is more than a threat—it’s a vow. But his idea of safety is a gilded cage, and the price of his protection might be the one thing I have left: my freedom.

She ran from one king only to be claimed by another. But what happens when the most dangerous cage is the one you never want to leave?

Ruthless is a standalone dark royalty romance with a possessive alpha hero, a marriage of convenience, and a strong, strategic heroine. If you love forced proximity, only one bed, witty banter that turns into filthy praise, and enough “touch her and you die” to make you swoon, you’ll be obsessed with this opulent and addictive story. Complete with a HEA.
