The stakes are high, but the secrets are buried bone-chillingly deep in the luxurious, ultra-private billionaire enclave of Paradise Grove, where the decadent sizzle of 365 Days meets the scandalous intrigue of Desperate Housewives in USA Today bestselling Booktok sensation Shain Rose’s dark and edgy romance for fans of Ana Huang, Rina Kent, Marni Mann, LJ Shen, and JT Geissinger.

He was only supposed to be a secret fling. A forbidden kiss stolen in the dark . . .

Not the cold-blooded monster who betrayed me.

Callahan Knight is the Diamond Syndicate’s perfect weapon with honed muscles, lethal control, and merciless loyalty. Even when taking out a rival cartel’s capo—my uncle—he doesn’t flinch. He shatters my family without hesitation, and I swear I’ll never forgive him for that.

But the Syndicate doesn’t care about my hatred. To secure their power, they demand more: A vow of marriage or watch everything we love get destroyed.

Now I’m the unwilling bride living in the luxurious prison of Paradise Grove with the man I refuse to call my soon-to-be husband. Instead, he’s the villain. Enemy number one. My tormentor . . .

But also maybe my undoing.

Because when he looks at me with the same fire we once shared, I can’t decide if I want to kill him . . . or kiss him.

Yet, I refuse to be distracted by his touch or piercing gaze. Instead, I’ll play the part, wear the ring, and say my vows all while I dig for his greatest weakness.

Because he may be the Syndicate’s deadliest weapon—

But I’m just as lethal as the monster I have to marry.
