The Best Man's Sin: A Forbidden Vow

He was never supposed to want her.

She was never supposed to need him.

Ivy Sinclair’s world shatters at 11:47 p.m. on a Tuesday.

Her ex’s revenge is everywhere — her name, her body, her private life exposed for the entire internet to consume. She’s trending for all the wrong reasons, and the life she built is collapsing in real time.

The person who shows up to put her back together isn’t her best friend.

It’s her best friend’s brother.

Roman Ashford doesn’t do messy.

Six years ago, betrayal taught him to lock his heart as tightly as his boardrooms — calculated, controlled, untouchable. But seeing Ivy broken on her apartment floor undoes something in him he thought he’d buried for good. Before the night ends, he moves her into the Ashford estate and claims her under his protection.

It was only supposed to be temporary.

A guest room. A security detail. A promise made to his sister.

Then temporary starts feeling dangerous.

Ivy is family in every way that matters to the Ashfords. Wanting her is the one line Roman swore he would never cross. But the longer she stays under his roof, the harder that line becomes to see… and the harder he falls.

As his father’s warnings turn into ultimatums, a multimillion-dollar deal hangs by a thread, and Ivy’s vindictive ex refuses to stay quiet, Roman and Ivy are forced to decide how much they’re willing to risk for something neither of them planned on.

Some sins are unforgivable.

Some are inevitable.

And some are worth committing twice.
