Flying commercial is the bane of my existence.
Until the fiery redheaded flight attendant with emerald eyes falls into my lap.
The spark between us is instant. And from the moment her body crashes into mine, I know I need more than just a few hours in the sky with her.
The next time our paths cross, she tells me she’s headed out of the country, and I don’t hesitate to make sure I’m on her flight.
Our time together is filled with a passion I didn’t know existed. And for a moment, I allow myself to imagine what it would be like if our temporary arrangement turned into forever.
Until a call in the middle of the night pulls me back to reality, reminding me that with the enemies I have, letting her get too close would make her my greatest weakness—one I can’t afford.
Four years later, fate intervenes. Because she’s back, serving drinks on my private flight, and she’s apparently been keeping secrets.
With one phone call, I learn she’s been raising my son while pretending I don’t exist.
Now, with my enemies closing in and our secret out, they’re both in danger, and I’m done playing this game her way.
She might not trust me, but I’ll stop at nothing to keep them safe—even if I have to drag her kicking and screaming into my world.

Spoiler-free Review
Sweetest Sin by Nikki AshMy rating: 5 of 5 stars
Sweetest Sin by Nikki Ash is the unputdownable first book in the Tempting Love series. A one-night stand with a dangerous mafia crime boss turns into so much more when Peyton, a flight attendant, crosses paths with Dominick on a flight that changes both of their lives forever.
This heart-pounding mafia romance had me hooked from the very first page. After their explosive night together, Peyton finds herself pregnant and raising her son alone until fate gives her and Dominick a second chance. Entering his world won’t be easy. Peyton wants nothing to do with the violence and danger that surround him, while Dominick is determined to prove he can keep her and their son safe. Their wicked chemistry is undeniable, but is it enough to survive the high stakes of love and family in the mafia underworld?
Nikki perfectly sets the stage with rich family dynamics, weaving in Dominick’s siblings and the complex loyalties that come with their violent history. THAT ENDING! It left me absolutely desperate for more. I’m counting down the days until Matteo’s story, Deadliest Desire, releases on January 8th.
Sweetest Sin is a fantastic, addictive start to this new mafia romance and absolutely one-click worthy
