Secret Baby for the Mafia Don

Rate this book
I’m the monster she’s been hiding from.
But now I’ve found her and
her secret…my heir.

For the first time in seven years, I catch a glimpse of my betrothed.
Then a knockout punch sends me to the ground.

Nothing will stand between me and what’s mine.
Not even the rival mafia family that's imprisoning her.

Our marriage was arranged in childhood.
Kate Aguirre belongs to me and it’s time to claim her.

But love is a luxury I don’t deserve because I’ve done unspeakable things.

Nothing can stop the inferno that burns between us though.
Even the cold monster inside of me is warmed by our fire.

But when I finally prove to Kate that she doesn’t need to hide—hers aren't the only eyes staring up at me.

I’ll tear the world apart to make her my wife and keep our son safe.

"Secret Baby for the Mafia Don" by Demi Ryder is a thrilling addition to the Billionaire Sinners series, delivering a dark and captivating tale of love, betrayal, and redemption. This third installment can be enjoyed as a standalone, though reading the previous books enhances the experience.

The story centers around the powerful and enigmatic mafia don who discovers that his betrothed, Kate Aguirre, has been hiding not only from him but also a life-altering secret—his heir. After seven long years, a chance encounter brings Kate back into his life, igniting a fierce determination within him to claim what is rightfully his.

The plot takes readers on an intense journey as the protagonist confronts a rival mafia family to rescue Kate. Their arranged marriage, planned since childhood, positions Kate as his destined partner, and he is unwavering in his quest to protect her and their son. The narrative masterfully balances the cold, ruthless aspects of the mafia world with the fiery, undeniable chemistry between the lead characters.

Demi Ryder's storytelling is both gripping and emotionally charged. The characters are well-developed, with the protagonist’s internal struggle between his dark past and the warmth he finds with Kate adding depth to the narrative. Kate's strength and resilience shine through as she navigates the treacherous path back to her true love.

The book is rich with twists and turns, keeping readers on the edge of their seats. The romantic tension and the eventual emotional payoff are beautifully crafted, ensuring that despite the morally gray and twisty journey, a happy ending awaits.

"Secret Baby for the Mafia Don" is a compelling blend of arranged marriage, second chance romance, and the gritty world of mafia rivalry. Demi Ryder's ability to weave these elements together creates a mesmerizing story that will appeal to fans of dark romance and thrilling love stories. If you’re ready for an intense, morally complex, yet ultimately heartwarming tale, this book is a must-read.

I spent a good portion of this book hoping that Elio would rain heck down on the Baldinis and bathe their world in blood. I haven’t been a Baldini fan in the past. I’m still not, although Grazia redeemed herself and went from the girl who was angry that someone else being kidnapped was going to ruin her wedding to a capable, formidable, interesting woman. I enjoyed that journey. Marco I’m still lukewarm about, and I think that Grazia’s brothers are despicable.
As far as Elio and Kate go, they have both grown since the beginning of the book, when Kate was immature and impulsive and Elio was impulsive and full of rage. Elio had a lot of baggage to work through after the abusive “training” his father put him through. I thought it was interesting that Kate’s pleasure/pain receptors are so strongly connected. I did enjoy reading about the love between Elio and Kate, and how they made each other better people.
But this was a very strange book. The kidnappers allowed the MMC to go home, and to visit the FMC while she was in captivity. Then there was a convenient coma, and a major Kumbaya moment. I got whiplash.
This book was written well, with good grammar and decent stylistics. And it was very readable. It certainly held the attention. It just made me scratch my head a lot, especially with the ending. I get that the Baldinis were main characters in the previous books in the series, so they couldn’t be condemned as horribly ebil and have this MMC rain blood and destruction on them. But the ending was beyond belief.
Because it was well written and interesting and I didn’t hate it, I’m giving it three stars.

Secret Baby for the Mafia Don is such a captivating story. This is Elio and Kate's story. Elio La Rosa is the oldest son in his family and Kate is the oldest daughter in her family. Their families have promised them in marriage, since they were small children. Both of their families are quite powerful. Elio's father has trained him to be a dangerous and brutal man to take over the family organization one day.

Elio discovers that Marco is marrying into the Baldini family and knows Kate will be there. Elio intends on getting Kate back, but doesn't know about his son.

Secret Baby for the Mafia Don is another amazing Mafia Romance book that I thoroughly enjoyed reading. I could NOT set my kindle down before finishing this book. The chapters flowed with such ease, that you could follow the story and not get lost in what was happening from chapter to chapter. Kate is promised to Elio La Rosa since the day she was born, Elio is the oldest son of one of the most powerful families in the US. While Kate is the eldest daughter of one of the most influential families in Mexico. The marriage between Kate and Elio was planned for them while they were both infants to help shore up their family bonds and trade alliances that would make their parents rich. In the beginning Elio is thrilled about marrying her, he liked enjoying women and told his parents that he wasn't going to agree to marry a "stupid girl" like Kate. However, once Kate grew out of the awkward teenage years and blossomed into a beautiful woman, Elio changed his mind about their pending marriage. I'm so happy that Elio and Kate ending up having a happy ending and our happy married with a lovely daughter. I'm definitely going to check out more books by this author. I would also HIGHLY recommend this books to other readers.

This is a complicated love story. Elio La Rosa has been groomed brutally to become the leader of his New York La Rosa crime family. He no longer understands tenderness or softness. Even his future love life has been laid out for him. He is to marry Kate, his childhood friend. Kate is the oldest daughter of a powerful Mexican family. Now that Kate has matured Elio certainly thinks she is hot. He can’t keep his hands off Kate, but Elio doesn’t know how to express his feelings. Kate though is in love with Elio and is a romantic. She wants loving words but what she hears makes her run. For years Elio has searched for his woman and finally, she is within reach ...but… she’s staying at an enemy’s home. Hot-headed Elio breaks in during a fancy family wedding and causes a scene. The mob family takes him prisoner along with Kate. Elio will make a great bargaining chip for getting better trade routes. It’s a mess. BUT… it all works out wonderfully in the end. Probably, is one of the best endings I’ve read. I received a free advanced copy of this story from Booksprout and these are my thoughts.

i read this book as part of an arc program. This is the third book in the Billionaire Sinners series. In this book, we pick up at the wedding of Marco and Grazia. Marco had helped Kate hide years ago when she realized she was pregnant by Elio, the man she was promised to in marriage. Kate overheard a conversation where Elio said he had no use for her after the wedding and she had a child. Kate decided to go in hiding to protect her baby. For years Elio searched for her, but Marco had hidden her and no one knew where she was. At the wedding, Kate brought her son and Elio showed up to claim her, only he was kidnapped along with Kate by rivals Luca and Enzo. They hoped to force Elio to turn over profitable trade routes. Meanwhile, Elio was determined to win Kate back. I really enjoyed this book. I liked Elio, he wasn't as bad as i first thought he was. I think Kate still loved him and he loved her, he just couldn't admit it. This was a good end to this series.

I have read this series and I think this book is the best one! I really enjoyed it! Kate was betrothed to Elio from childhood. Kate has always loved Elio. Elio was raised to be the new head of the family by his father who trained him to be ruthless. He has done unspeakable things that he cannot forgive himself for. A misunderstanding of a conversation Kate overhears Elio having sets off a string of actions to hide from Elio by a pregnant Kate. This leads to years later Kate and her child being kidnapped by the Baldinis to get at Elio’s business. There is so much action, drama, plot twists and in all this madness a possible way to love and a HEA. I found Kate to be my favorite female lead character in the series so strong and a fighter. Elio once opening his heart became a great lead also. Loved their story.

Wow, this book was so good grew up as children knowing their parents organised their marriage all their lives. Kate, escaped to her good friend and when her fiancee Elio La Rosa, came looking for her she lied to him and he left angry. Seven years her friend has kept her in hiding, now Kate is watching her friend getting married. Elio turns up and starts fighting until she spoke then things go down hill after that. There was action, suspense, danger, violence, enemies, kidnapping, betrayal, lies, secrets, twist, passion, pleasure, and maybe even love. This was a fantastic book, I highly recommend reading this book you won't be able to put down the book.

For me this book was hard to get into as it is not normally what I read. This book made me feel like I was a fly on the wall watching everything unfold. Kate has such patience with Elio and his lack of wanting to show her any emotions. Then for Kate to remain hidden for seven years with a child that Elio didn’t know about was a feat in and of itself. I honestly couldn’t do what she did and not get stir crazy sooner. When Elio pops back into her life everything changed, Kate got scared and felt more trapped than before. By the end of this book I truly appreciated Grazia and her putting her brothers in their place and helping Kate and Elio. Not to mention peace between mafia families is uncommon but felt so surreal reading about it and how it was held together was amazing.

Hiding their son

A great dark mafia romance, full of action, drama, enemies-to-lovers, steamy romance, secrets, suspense, danger, kidnapping, misunderstandings and passion with some great twists.

Kate and Elio have been betrothed to each other since childhood but after a misunderstanding she runs to her friend Marco who agrees to pretend her pregnancy is with him and then helps her to hide and keep her baby safe.

Seven years later Marco is getting married ("Stolen by the Enemy") and Elio gets in, having followed him for years in the hope of finding Kate. When a fight starts Kate does her best to stop Elio who is determined that she is still his; but more problems arise with hostilities between the rival families leading to the bride's brothers kidnapping her.

Elio and Kate have been betrothed by their parents, everything was going fine until she over heard one of his conversations. She needed to get away to protect herself and their unborn baby. She tells him that the baby is Marco's. Fast forward seven years, Elio is still looking for Kate, he crashes Marco's wedding to find her.

This picks up at the end of the last book but can be read as a standalone. Grazia's brothers abduct Kate and her son, Mateo to make Elio give them a piece of his operations. Can Elio find out what went wrong between him and Kate back then and protect his son and her from her captures?

This is an emotional journey for both characters.

Secret Baby for the Mafia Don is an arranged marriage, dark mafia romance with a twist of second chance love and kidnapping. It’s the third book in the Billionaire Sinners series. It can be read as a standalone, but for the best experience try the books in order. This is Elio and Kate's story. Book 3 picks right back up at the wedding of Marco and Grazia. There was action, suspense, danger, violence, enemies, kidnapping, betrayal, lies, secrets, twist, passion, pleasure, and maybe even love. I liked the character development and how I could picture myself as the character. Watching the two of them reconnect and piece together a new relationship after everything that happened was very intense. Loved the addition to the series!

Absolutely fantastic. It has been a while since I read a book that had me this enthusiastic. I absolutely felt engaged in Elio and Kate's relationship. Kate and Elio's relationship almost was destroyed because they were not honest with each other, Elio because he was trying to protect Kate, and Kate because she made assumptions. Elio and Kate really needed to learn how to communicate earlier and it would have skipped all the heartache and turmoil that they went through. I absolutely loved the story. I do not know how Demi Ryder escaped my attention, but I am glad I discovered her because this book was awesome.

I love mafia stories and this story immediately kept me glued to my book. We are taken into the lives of Elio and Kate, they have been promised to each other since they were children. When one day she overhears a conversation, it is the reason she went into hiding for a few years. Years later they meet again at her best friend's wedding. From that moment on things get exciting because she and her son are kidnapped by his rival. A great story full of drama, action, danger. unexpected twists and lots of steam.

Elio and Kate were betrothed since they were teens and soon, they will be getting married. That is until she overhears something that shatters her heart. She runs to a friend for help and when Elio catches up, they both lie to him in order to get him to leave. Seven years she has been in hiding but now her friend is getting married, and she wants to be there. Elio learns she is there and shows up unannounced which causes a fight between him and the Baldini family. She and their son are kidnapped after Elios is knocked out. Will he be able to save them from his enemy? Will she give him another chance?

This is a great story I just didn't expect some of the things that happened during this story to happen. Any other mafia story things would've been different if someone kidnapped the loved ones of a rival family. This is a well written and very entertaining story. Its a book any book lover would enjoy.

These two have been betrothed since childhood, but when Kate overhears somethings, her heart is broken and she runs. Now 7-years later Elio finds Kate, but can he keep her safe?
This is a well written action packed story, with family, friendships, enemies /lovers, danger, suspense, intrigue, misunderstandings, passion, emotions, secrets, lies, drama, rivals, an arranged marriage, kidnapping, and love, which leads to an entertaining, twisted, and spicy, dark romance.

This is Book 3 in the Billionaire Sinners Series by this author, and can be read as a standalone. It is a dark mafia romance between Kate and Elio. These flawed but likeable souls and the unique plot make for an intriguing read. It is a second chance love story with drama and steam, danger and suspense, sexual tension and chemistry, and twists and turns, plus appealing secondary characters to keep the reader interested. An engaging page turner.

Demi spins another great romance filled with Mafia mayhem. Elio and Kate made the pages of the book sizzle even though were enemies with an arranged marriage. However, when Elio comes for Kate, he now has a surprise waiting for him as well. This was a great read and I definitely recommend. I wish I could make this book series into a mini-TV series because it would definitely make for a great movie.

Betrothed at Birth

Betrothed at birth Elio and Kate find themselves in a predicament when she overhears a phone call and misinterprets it. The loss of seven years is profound but where he finds her and the secret she has carried ignites a fire within him. With wonderfully written twists and turns, this story will take you on a ride of enjoyment.

No

If I could give it a zero I would. I liked nothing about this book. Skimmed through the sex scenes they were borderline disturbing from the little I read. Violent and read as low budget porn. Also they covered quite a bit of the pages🙄. Some of the characters from the old books in this series suffered because I could not stand them by the end of this book. They were trash and h got on my last nerves! Good luck

A very good Mafia story full of misunderstandings, threats and angry family members. All the ingredients needed for a page-turner. Elio and Kate were betrothed nearly from birth, things don't go as planned when they are old enough to marry. How they get their HEA is well-written and highly recommended reading.

This book was so amazingly written. Demi is one of my favorite authors. I feel in love with the characters from the start. And yeah, maybe at first, I thought Kate deserved so much better than Elio, but in the end I'm glad they fell in love and were both so happy. Also, ladies, just remember...real men show those emotions when it is most important ;).
