For three months, your boyfriend has been cheating on you.

And the man who wants to marry you has known the entire fucking time.

Meet Gavin Crowe.

Twenty-two. Six-foot-four. Tattooed. Filthy-mouthed. Ridiculously wealthy. A dangerously charming political science senior with light-blue eyes, a devastating dimpled grin, and absolutely no business being as persuasive as he is.

He’s also arrogant, hilarious, possessive, spectacularly impulsive, and completely fucking obsessed with you.

There’s just been one tiny problem.

You already had a boyfriend.

Xavier Bell. Your longtime boyfriend, Gavin’s rival, and the asshole who’s been sleeping with Cherie Spicer behind your back.

Gavin found out three months ago.

He didn’t tell you.

Instead, he watched, waited, and fell even harder for the one woman he wasn’t supposed to have.

Then your father discovered Xavier’s betrayal.

And made Gavin an offer.

Take Xavier’s place as your Intended in the Obsidian Society.

Gavin said yes.

Obviously.

Now it’s Halloween night at Casanova, and beneath the chandeliers of Natural Falls’ most decadent nightclub, the Obsidian Society is holding its annual oath ceremony.

There’s a masked man waiting to claim you.

A princess-cut black obsidian ring.

A vow of fidelity, protection, and provision.

And a very smug bastard who’s been dreaming about calling you his.

Surprise, Jewel.

Your boyfriend’s been replaced.

Your father helped arrange it.

And Gavin Crowe has absolutely no intention of pretending he’s sorry.

Unfortunately, Xavier isn’t going quietly, Cherie’s about to become everybody’s problem, and three powerful families have decades of friendship, business, and Obsidian secrets tangled up in this spectacular fucking disaster.

Oh, and one more thing?

Gavin turns twenty-three tomorrow.

He’s already booked the country club, invited half of Natural Falls, and planned one hell of a birthday party.

Preferably with his brand-new Intended on his arm.

Your boyfriend cheated. Your father made a deal. And the most dangerously charming asshole you know just put a ring on the table.

Whether you accept it?

Well, that’s where the fun fucking starts.
