Daddies of the Underworld: A Whychoose Mafia Romance

Rate this book
When you run from three older mafia kings…
you better pray they never find out you ran with their baby.


Five years ago, I belonged to Matteo, Dante, and Luca—
the three ruthless men they call the Demons of the Underworld.

They shared everything.
Their power.
Their empire.
Me.

Then one terrifying night sent me running.

I disappeared before they could stop me.

And I never told them I was pregnant.

For five years, I've kept our little girl hidden from the dangerous world her fathers rule.

Then the Demons finally find me.

One look at my daughter…
and they know.

Their eyes. Their blood. Their little princess.

I expect punishment.
Instead, three possessive mafia kings take us home.

Their protection.
Their rules.
No running again.

And the way they look at me makes one thing terrifyingly clear—
Five years haven't made them forget.

I'm still theirs.

And this time, all three intend to keep me.

Because the Demons of the Underworld just became Daddies…
and Daddy doesn’t like it when his girl runs.

She ran from three dangerous men. She never told them she carried their child.

Nina survives by watching, planning, and never letting anyone close enough to become a weakness. Matteo, Dante, and Luca are the exception. Powerful, possessive, and dangerous, they draw her into a relationship built on trust, protection, surrender, and a desire none of them wants divided. Each man reaches a different part of her: Matteo gives structure to the chaos, Dante makes protection feel physical and absolute, and Luca reminds her that intimacy can hold laughter.

Then fear destroys what they built. Nina runs before she can tell them she’s pregnant, and for five years she builds a hidden life around keeping her daughter safe. When the three men finally find her, the truth between them is impossible to ignore. Finding them again forces Nina to face more than the secret she kept. She has to decide whether the men who once felt like danger can become the people she trusts enough to call home.

Reunion doesn’t erase the damage. Matteo still leads with control, Dante protects like danger is always one step away, and Luca slips beneath Nina’s defenses with warmth and humor. They’re angry, relieved, hurt, and still completely devoted to her, but love isn’t enough without rebuilding the trust they lost. That choice becomes harder when their past refuses to stay buried.

As old danger closes in, Nina refuses to be protected through silence again. Matteo learns that leadership means listening, Dante lets tenderness exist beside his instinct to guard, and Luca’s charm becomes something steadier. Together, the four begin turning possession into partnership and desire into a choice they keep making.

A dark, ultra-steamy, age gap, second chance, reverse harem mafia romance with secret baby, protective dominance, shared possession, forced proximity, and chosen family. It’s about trust after fear, love after separation, and finding the courage to stay when running has always felt safer.

The Elevator Pitch: A guarded woman who vanished from three dangerous men is forced back into their orbit when the life she built in secret collides with the world she escaped. What begins as a volatile second chance becomes a struggle to rebuild trust, redefine family, and decide whether love can survive the fear that once tore them apart. With three fiercely devoted men refusing to lose her again, desire and danger tighten around a bond that has already survived five years of separation.

Nina returns to the Villa to work. She's broke and exhausted and needs the money, hence her return, since she gets paid, and somewhere to stay. Except this time, things are more dangerous, with lots of security and men in suits and women in expensive dresses and jewelry. She meets Luca after tripping and spilling her champagne tray over him. She fears she will lose her job, but Luca is amused by the incident and tells her not to worry. She later meets his associates, Matteo and Dante. Later, Nina overhears something and, despite signing an NDA, finds Luca and tells him what she heard since it seemed to involve him. He tightens security and puts Nina in a suite to keep her safe. Then her brother Marco, whom she hasn't seen in years since he disappeared, suddenly shows up looking for her. Then things start happening, and Marco gets blamed. Then Nina appears to be set up for the sting too. Marco then disappears again. Nina overhears the three men talking and decides to go herself. A storm that night is the perfect cover. But Nina is hiding a secret from the three men. Fast forward five years, and the men who have been searching for Nina get a lead from a contact and finally find her, to their relief. Now the men have found her; the person who is after her and her daughter, Sofia, finds her too, and their lives are in danger. The author keeps you turning the pages with all the action, twists, and turns that you dont see coming.

Nina returns to the Villa broke and exhausted, needing the job and a place to stay. Security is tighter this time, the guests richer and more dangerous. She meets Luca by accident—tripping and spilling champagne all over him—and fears for her job, but he’s only amused. Later she meets his associates, Matteo and Dante.
Despite her NDA, Nina overhears something that seems to involve Luca and warns him. He tightens security and moves her into a suite for protection. Then her long-lost brother Marco reappears, only to be blamed when things go wrong. Nina is framed too. Marco vanishes again.
Overhearing the three men, Nina decides to act alone. A storm provides cover—but she’s hiding a secret from them.
Five years later the men finally track her down, only for the people hunting Nina and her daughter Sofia to find them as well. Their lives are in immediate danger.
Packed with action, unexpected twists, and relentless tension that keep the pages turning.

Review of advance copy

Daddies of the Underworld by Lisa Cullen is a fun, steamy read that delivered plenty of drama and heat. The forbidden romance element added an extra layer of tension, while the mafia setting brought danger, suspense, and plenty of high-stakes moments. The chemistry between the characters was definitely one of the highlights. Each of the men brought his own personality and dynamic to the relationship, making the why-choose aspect entertaining and kept the story moving. I also enjoyed the mix of protective alpha energy, emotional tension, and spice. This is definitely a book for readers who enjoy their romance on the darker and steamier side. Overall, Daddies of the Underworld was a steamy, dramatic mafia romance with plenty of possessiveness, danger, and forbidden chemistry!

Dangerous and Complicated

Nina finds herself pregnant by three dangerous men who protect with silence. When she runs out of fear, raising her daughter alone for years until she is reunited with Matteo, Dante and Luca. From that moment on this story gets exciting, suspenseful and complicated. It was definitely an entertaining read.

Great read

Definitely a great read unfortunately has the lack of communication issue which does annoy me but the story flows well and isn't too long. I love that they have a HEA and the little girl made me laugh so much

I loved this book. There were so many intricate pieces that were put together seamlessly. Each man had his own idiosyncrasies and that just brought more to the storyline. Sophia was very bright for her age and never missed anything. She was so intelligent. There was so much I loved about this, there are no words to fully describe my feelings.
