Onyx Santo.
Cold-hearted, harsh, and a brutal adversary.
They call him a Devil. I call him my nemesis.


His designer suits, expensive shoes, flashy car, and cruel intelligence can't hide what he is underneath.
Empty.


He fooled me once, and I swore he'd never get a second chance.
There is nothing he can do to redeem himself in my eyes.
As my most hated rival, the only time he makes me smile is when I've bested him in the boardroom.


But someone far worse is out to get me. Perhaps...even hurt me.
The police have no leads, and I have no idea who it could be.
I do know one man who doesn't play by the rules. One man who could protect me.
I'd rather live in fear than ask for his help.


*Ruthless Devil is a full-length stand-alone, billionaire, office, enemies-to-lovers romance that is intended for mature readers, and ends with an HEA. If you are not a fan of morally grey alphaholes, or heroines who aren't afraid to tell them to stick it where the sun don't shine, then you should keep scrolling.
