Her Mafia Billionaire Secret Baby: Dark BWWM Billionaire Romance

Rate this book
He doesn’t know he’s a father. But he knows she’s his.

It was supposed to be one night.
One stolen dance. One look across the room that made me forget everything but him.

Declan Quinn wasn’t just Eliana’s mysterious best man—he was temptation wrapped in tailored silk and smoldering promises. I let myself fall, just for one night. And now I’m pregnant.

I’ve always been the strong one. I’ve balanced school, jobs, and chemo care for my sister without falling apart. But when my stalker ex resurfaces, I can’t protect myself alone. And the only man I can turn to is the one who doesn’t know he’s the father of my child.

Declan
I don’t do softness. But Amara cracked something open in me I didn’t know existed.
Now she’s back in my world—and in danger.

She thinks she can face it alone. She doesn’t know I’d burn the world down to keep her safe.
She also doesn’t know what I’ll do when I find out the truth.

Her Mafia Billionaire Secret Baby is a standalone, swoon-worthy, dark BWWM mafia romance filled with heat, danger, found family, protective alphas, dark mafia romance, a second chance billionaire romance, and love that refuses to die. Expect tension, betrayal, second chances, and a guaranteed HEA—because some men don't run from fatherhood. They fight for it.

Definitely reading this again

This was a great read but, it doesn’t seem like the end, they did not find the crazy Vargas, or solve the problem of getting rid of his father either. I would love to read Amara mom story she must of been a bada$$, I would love to read how they came to be. So since it is 5 Quinn will it be 5 different stories, so far we have the 2 I know it will be another because of the crazy people Vargas and his dad. But when ever it comes out I already know I will probably read the first two over so it feels like I am reading them together.

Family First!!!

Her Mafia Billionaire Secret Baby is the second interracial romance in the Quinn Syndicate. It is the love story of Amara Franklin, African-American plus Puerto Rican and Declan Quinn, Irish American. Amara is the sister of Eliana and Declan is the brother of Aidan from the first book in the series. We met them in Her Mafia Billionaire.

Their characters, as are other characters in this book, are more fully developed than they were in the first book, especially Amara's and Eliana's parents. We also know more of their back stories but it doesn't make them more realistic. It seems as if all of the main characters are related to the Irish mafia or the Italian mafia or some other mob or syndicate or other gangster group. Zoe, Amara's roommate, father is head of the Greek.

Family comes first with Amara and Declan's family legacy is most important. Both seem to have the same mantra or code: Control. Protection. Loyalty. Honesty. They both have to choose between the person they love or their family legacy. One blurb describes the book where "protection meets passion and survival demands sacrifice" which is an overstatement. There are just too many grammatical errors which pulled you out of the story. Several passages are repeated as if they were cut and pasted. This was extreme irritating and lowered my rating. Still, if there's a book with Zoe and Caden, I would purchase and read it.

There is "danger, darkness, devotion, overwhelming desire and an unexpected consequences". As with most romance books there's a guaranteed HEA!

Dark Mafia Secret Baby

I love how this author writes but the heroines comes off stupid in almost every book. There is no rational thought process that allows the conclusions they make. Pregnancy abortion adoption without any thought of speaking to the father who is not abusive or has done anything to her. Why would you believe someone who mistreated you vs someone who never did anything bad to you. They act irrationally not giving people they say they love a chance to explain themselves. He put his life on the line for you and you run away. The men in her books do too much. I am over the same story in different settings.

I enjoyed this story. And it was a different take on secret baby for me. Usually the baby is already born and the father finds out about him/her after that but he found out while she was pregnant. Different but good. And I enjoy a happy ending but I’m hoping for another story. I need to know what’s going to happen to Montoya.

OMG!

This Quinn series is awesome! I am hoping that the rest of the brothers will get a story, and let's not forget Zoe loved her as well. So if you want an extra good mafia story these two belongs in the top 2..lol

Her Mafia Billionaire Secret Baby

Only reason for the 4 Stars is that Amari (FMC) is supposed to be so smart and tough; but believes everything that came out of Vargas mouth. Declan (MMC) should have let Amari sweat it out for forgiveness. Ending????
