Rate this book
MAFIA. COWBOYS. RIVAL FAMILIES. An explosive arranged marriage!

Gianna

I was raised to become a leader. I promised my father I’d do whatever it takes to forge my legacy.

So I forced one of the most powerful mafia families into an alliance- and now I’m trapped on a ranch with a grumpy cowboy for a husband.

I’ve spent my life manipulating and killing my way to power, and I’ve found the one man that won’t work on.

Colten Sterling.

He thinks I’m nothing but a mafia princess sent to destroy his family. He’s not wrong. That’s the mission I was sent on.

What he doesn’t know is that I’m done being a pawn.

He brings out a side of me I never knew could exist. A happy version. And I finally learn what true love really means.

But, it’s better that he remains thinking the worst of me.

After all, monsters don’t raise daughters to love. They raise them to betray.

Except the longer I live on Sterling Ranch, the harder it gets to remember which family I’m fighting for— and which man I’m supposed to ruin.

Because Colten won’t give up on me. He looks past my scars and fights for my heart.

I’m no longer just a princess. I’m the Queen of this empire and now that I’ve found my King… we’re coming for it all.



Colten

My purpose in life is two protecting Sterling ranch and eliminating anyone who threatens my family.

Until I’m forced to make a deal with a devil in high heels and red lipstick.

Gianna Milano is devious, dangerous and devastatingly beautiful.

And now, my wife.

I know I’m just a stepping stone to her ultimate taking over her family empire.

What I didn’t expect was to fall so hard for her.

She didn’t just take my last name, my viper stole my heart.

But when Gianna is handed the keys to the kingdom she’s spent her life fighting for, everything changes.

I vowed to make her regret ever saying I do, but as enemies start closing in, I find myself making another to never let anyone hurt her ever again.

I’m prepared to lose everything if it means Gianna gets another shot at life.

⭐⭐⭐⭐⭐ 5 STARS! 🖤🔥

Okay, Luna Mason seriously never disappoints me!! I was hooked on Colten and Gianna from the start! 😍

Gianna was everything I love in a FMC! Strong, stubborn, and not afraid to stand her ground. And Colten?! That grumpy, protective cowboy had me swooning! 😮‍💨🤠

I loved the push and pull between these two! Their chemistry was insane, but it was the moments when they finally started letting their walls down that really got me. I loved seeing their relationship turn into something so much deeper.

The tension, the spice, the drama, and all the emotions had me eating this story up! I honestly didn’t want it to end. Another Luna Mason book that has me wishing these characters were real! 🖤
