The Highest Bidder by Arianna Fraser

She thought being sold in The Auction was just for one night. She was wrong.

Ethan…
I find lost things and people for the MacTavish Scottish Mafia.
Sometimes, I return them to their proper owner. Sometimes, I make them disappear.
When I’m charged with bringing back runaway Sloan Masters to her father, the instructions are disturbing: If you can’t extract her, unalive her. I don’t hurt women, I protect them. But I still have a job to do. When I find her, there’s one more wrinkle. To retrieve her, I’ll need to be the highest bidder at her auction. This pretty little runaway is expensive, but her sweet body is worth every penny. She’s fascinating; secretive and fueled by fury, and she’s not willing to trust me. Taming her will be the biggest challenge of my life.
I’m ready for it.

Sloan…
They call him the Scottish Demon.
His name is uttered like a curse throughout the crime world, a horror story parents tell to children to make them behave.
So when he comes for me, I can’t run fast enough. Ethan MacTavish has the body of a Greek god and the charm of a sociopath bent on world domination. I can’t tell him the secret I’m hiding, the reason my stepfather sent the Demon after me. The more I fight, the tighter he holds me. Can I trust him with my secret, or will he make me disappear, too?

The Highest Bidder is a standalone dark mafia romance with a HEA and no cheating. If you love your men morally grey, you’re going to fall in love with Ethan.
