He’s the stepbrother I’m forbidden to crave… and the only man who’s ever made me beg.

Aurora Hart never belonged in the world of billionaires—until her mother married Victor Langford and delivered her straight into the lion’s den: Cassian Langford, thirty-two, cold as winter steel, and worth more than most nations. The tabloids call him ruthless. She calls him the man who kissed her senseless the night of the wedding, then vanished like a ghost.

Now she’s trapped in his Hamptons palace for the summer while their parents sail Europe. Separate wings, strict rules, zero contact.

They last three days.

Late-night swims turn into desperate, filthy encounters against marble and glass. Every “good girl” growled against her throat makes her wetter, needier, more willing to risk everything for the one man she’s supposed to hate. Cassian warns he doesn’t do gentle. He doesn't love.

Aurora says she only wants his body—until his touch starts feeling like salvation.

But secrets this dark don’t stay buried. When the truth about their parents’ marriage explodes, Cassian’s empire hangs in the balance, and he’ll have to choose: protect the legacy he’s spent his life building… or claim the stepsister he’s been obsessed with since she was fifteen.

Filthy. Possessive. Shockingly twisted.

A standalone forbidden billionaire romance with praise, light degradation, a secret that will leave you gasping, and an HEA so intense it burns.
