Mercedes Ron Culpable (3 book series) my fault, your fault, Our fault.

And her new stepbrother Nicholas is the most spoiled of them all. Arrogant, aloof, and viciously attractive, Nick is everything she hates, especially when she learns his bad boy persona isn't just a façade. She's spent her life running from danger, and Nick is danger incarnate. Yet neither of them can prevent the powerful attraction that flares between them—enough to turn their worlds upside-down and tempt them beyond all reason.

But Noah's past may be even more dangerous than their forbidden romance. And if he wants her, Nick will have to decide if he's willing to risk everything.
