The Killer & The Mob Boss

Rate this book
He’s all danger and dimples, she’s all knives and trauma, and the banter and blades are on point.
Romance? Not exactly. Obsession? Absolutely.

Welcome to foreplay, Isadora Blackwell style.

*******************************************************************************

Love like this doesn’t come with flowers. It comes with scars.

*******************************************************************************

Anastasie Laurent vanished once to survive. Now, she’s back to finish what was started. Her past is soaked in blood and secrets, buried alongside the man she once loved and the life she was never meant to escape. But when a rival family resurfaces, threatening the last pieces of the world she’s tried to protect, Ana stops running. It’s time to burn everything down.

Cole Cavallo is no longer the prince of the mafia. He’s its king. After a brutal war leaves his family in ruins, he returns to Chicago to rebuild his empire, harder, colder, and deadlier than ever. What he doesn’t expect is her, a woman he once helped save from the thing that once changed both their lives forever.

Ana steps into his war with a body count, a kill list, and no intention of being anyone’s salvation. But her past is his future. And every name she’s hunting is a threat he can’t afford to ignore.

This isn’t a reunion. It’s a reckoning.

The Killer and the Mob Boss is a brutal, sultry, blood-stained love story about two monsters who were never meant to survive, but just might save each other anyway.

Perfect for readers who like their heroines unhinged, their mob bosses feral, and their happily ever afters paid for in blood.

Swearing, spice, and everything not-so-nice with violence and a little bit of gore thrown in.

Some writers craft fairytales.
Isadora Blackwell crafts firestorms.


A lifelong student of human darkness, betrayal, survival, and forbidden desire, Isadora doesn’t write to comfort. She writes to unearth the wild, terrible beauty that lives under your skin and dares you to fall in love with it.

There are no happily-ever-afters here.

Raised on a steady diet of classic tragedies, dark romanticism, and the sharp thrill of crime dramas, these romances sting.

Delivered in a lush, brutal, electric voice, her happily-ever-desipte-everything tales are not slow dances, but knife fights disguised as kisses. And the characters are bloodstained, battered, and breathtaking survivors of.

If you’re looking for fragile love stories tucked safely away from danger, you’re in the wrong place.

If you want characters who bleed, betray, and burn for each other?

Welcome home.

A Few Things You Should Know

Genre-bending is the rule, not the exception.

Expect dark romance, psychological thrillers, and twisted loyalties. Sometimes all at once.

There are no perfect heroes here. Only survivors you will love too much and villains you’ll secretly root for.

Love is never painless, but it’s always worth the scars.

High-stakes dark mafia romance. This is the perfect mafia romance, it's the darkest kind. Deranged and disturbed. All the elements someone would seek in a mafia romance. You could feel the tension through the pages. It was written well and impossible to put down once you've started. Isadora Blackwell hit the mark with this one. Morally grey with steaming tension.
I know there is audio coming for this book, but I usually don't do audio. However, this is one of those I think I would enjoy.

Dark mafia romance done perfectly. The tension and chemistry between the 2 main characters is exactly what I love!
If you are looking for a FMC who is fierce and independent and a MMC who can't seem to stay away from her with definite touch her and 💀 vibes, then this book is for you!
It was beautifully written, and I can not wait to see what else Isadora has in store for us!

I absolutely loved the sassy, witty banter between Anastasie and Cole - it kept me laughing even in the darkest moments. I’m usually not a fan of violence or gore, but in this world, it’s all about revenge and survival, and Blackwell handles it perfectly. The level of detail in her writing is incredible, and the huge shock closer to the end completely caught me off guard. Dark, intense, and utterly addictive - I can’t wait to see what she writes next!

A spicy mafia romance between a killer and a mafia boss with an instant attraction. The main characters, Ana and Cole, are an interesting couple with fun banter. Ana has a particularly interesting back story. Oh, and the spice is indeed spicy. It is full of action, deception, and dealing with loss.
I look forward to reading more in the series.
