Merciless Heir

Never trust a grumpy billionaire who hires you to steal from his own family-especially when he locks you in his penthouse until you deliver.

Kingston Sinclair wants one thing: the priceless tiara his family's been hoarding for generations. Not for some sentimental fairytale. For cold, hard cash.
I should have walked away the moment he cornered me in that hotel bar, all brooding intensity and dangerous promises. But when the FBI's former top art investigator gets shot and shoved into early retirement, you take the jobs you can get.

Even if it means betraying the sweet grandmother who hired me first.

The deal was simple: Find the tiara. Get paid by both Sinclairs. Keep my mouth shut about working all sides. What could possibly go wrong?

Except Kingston doesn't trust anyone. So now I'm trapped in his Manhattan penthouse-"for security purposes"-with a man who watches me like I'm the real treasure he's hunting. He's grumpy. Controlling. Absolutely ruthless when it comes to getting what he wants.

And what he wants is becoming dangerously unclear.

Every clue we uncover pulls us deeper into his family's buried secrets. Every night in forced proximity breaks down another wall between us. His hands on my waist when he thinks I might run. The way he growls my name when I challenge him. The moment I realize I'm not just risking my reputation anymore.

But Kingston's still planning to destroy his family's legacy. I'm still lying about who really hired me. And the truth we're about to uncover?

It's worth killing for.

Some treasures are meant to stay buried. Some hearts are meant to stay guarded.

And some billionaires are too dangerous to love-even when hating them becomes impossible.
