The Story

Eliana:

My first husband was no good. He beat me, betrayed me, and when the chips were down, instead of having my back, he tried to put a knife in it. Now, I've rebuilt my life in Philadelphia, far from the horrors of Florida. A job with Aidan Quinn, the billionaire genius behind Quinn Technologies, is supposed to be my fresh start. Except, Aidan is more than just my enigmatic boss whose intensity both terrifies and tempts me. His dealings in the shadows hint at truths darker than I've ever known. And when danger strikes again, I realize Aidan is not just a savior but a sinner—a man with his own dangerous ties to the underworld.

Aidan:

Power. Control. It's what defines me, whether in boardrooms or the shadows of Philadelphia's underbelly. Until Eliana Robinson, with her sharp mind and secret pain, walks into my life. Her vulnerability draws me, but her lies ignite my suspicion. Eliana is hiding something, and in my world, secrets can be lethal. When her past comes hunting, my resolve shatters. To protect her, I'll wield the full force of my empire. But will she embrace the dark protector I am—or fear the monster she sees in me?

Reader Reviews

⭐⭐⭐⭐⭐

"This was a very captivating book. It is one of the very best Mafia I've read in a while. Quinn is one of the 'best book boyfriends' to come along too. Rich and Fine and generous didn't stack up to protective, caring and dangerous. Action, adventure and Steam from cover to cover. Worth every Star!!!"
