The Right Wrong Promise: A Grumpy Single Dad Romance

by Nicole Snow

The gruffest broken single dad finds home with a spitfire heiress in this stormy and spicy romance by Wall Street Journal bestselling author Nicole Snow.

I inherited a freaking family.
Thanks, Gramps. I expected the lake house, the repairs, and the weird little secrets you left behind.
But sharing this place with Kane Saint and his kids?
Holy potato.

Don't laugh at his name.
There's nothing holy about a man this guarded and growly and scary fine.
He's at war with everything except his adorable munchkins.
It's a classic standoff the instant I let him stay after an awkward mix-up.

I go to work looking for my grandfather's final cryptic gift.
Saint Dadzilla goes to work on me.
A helping hand I never asked for.
The warmest laughs over breakfast feasts.
And when one stolen kiss claims my soul, I forget this is clinically insane.

I'm in shambles.
Every flaming night whispers promises we can't keep—especially when Gramps' legacy has teeth.
What happens if playing house with the wrong man feels like coming home?

Ms. Snow is always a winner for lovers of well-written steamy romance
I have been reviewing Ms. Snow’s books since 2018 but was reading them well before that. She never fails to deliver a satisfying romance in entertaining circumstances covering every trope imaginable. In this grumpy single father meets irritatingly irresistible wealthy woman, we get some of her best deliciousness.
Margot Blackthorn is one of THE Manhattan Blackthorns, heiress to a very impressive estate and at 25yo looking to make a name for herself in the design industry. Her favorite person in all the world, her PopPop has left her the lake house in Sully Bay, Maine with a puzzle to solve. When she arrives however, she meets Kane Saint who at 36yo has twin nine-year-olds, Sophie and Dan plus an absentee ex-wife; Kane and kids have rented the lake house for a getaway. He is trying to avoid a situation in NYC and his children love an adventure. What happens when the grumpy single father meets the no-nonsense heiress? Is PopPop playing matchmaker from the great beyond? Sink your teeth into this delectable romance with intrigue, romance, intimate scenes with a narrative that almost had me coming just from reading it! I volunteered to review an ARC of this book through Booksprout.

What a great read and addition to the Blackthorn Inheritance series. Margot is the younger sister of Ethan and best friend of Hattie from the first book in the series, Vows we Never Made. It picks up shortly after the first one ended.
Margot inherited her grandparents’ lake house on the coast of Maine. When she decides to check out the property and attempt to discover what her grandfather had left her in his will she encounters a divorced dad and his 9 year old twins are renting the property. She agrees to let them stay and the story takes off from there.
Many pieces are in play with grudge holding neighbors and an unknown person skulking around leaving ambiguous threats.
There are a few nods to previous series and characters from other books which felt like a little hug from the author.
I received an advance copy of this book in return for an honest review. I will say I highly recommend this one and can’t wait for the cousin’s story!

Great Read

Love Margot and Kane’s story. Love how the two of them meet and how they decided to cohabitate together. Love how they fell in love and how they protected each other.
