Forbidden Sins

Rate this book
He’s protected me all my life. But the only thing he can’t protect me from is himself.

I’ve been raised all my life to be the dutiful daughter of New York’s most powerful mafia boss. Protected by a man who has been my bodyguard since I was eighteen, I’ve never had anything to fear, or wanted anything that I couldn’t have.

Until a job gone wrong robs me of my brother, and the only person I can turn to is the man I’ve been trying not to want for three years…and shouldn’t love.

Now the only remaining child of the Gallo family, arranging a marriage for me becomes my father’s top priority. The man he chooses for me is powerful, wealthy, connected—and cruel to the core. When a desperate moment sends me fleeing in the arms of my bodyguard, I’m forced to confront a desire that I should never have allowed myself to feel—and a forbidden love that defies every rule I know.

I’ve never been allowed to choose. But if I could, I’d choose him.

Even if he’s forbidden. Even if it’s a sin.

Prepare to be captivated by the sensational world of M. James, the mastermind behind a genre-defying realm of romance and intrigue. With a pen dipped in passion and a heart that beats to the rhythm of forbidden desires, M. James weaves tantalizing tales that will leave you breathless and yearning for more.

Follow her to the dark side where strong heroines fearlessly navigate treacherous paths and damaged heroes find solace in their darkest corners. Her words will wrap around your senses like a seductive embrace, transporting you to a world where love and danger dance a wicked tango.

M. James resides in the suburbs of Chicago but lives for the big moments that make life interesting. Although writing brings her passion and darkest fantasies alive, watching suspenseful thrillers with her two dogs and loving husband brings her excitement in the most exhilarating way. Nonetheless, getting lost in a dark mafia romance along with a tall glass of wine makes any day a bit juicier.

From enemies to lovers to forbidden romances, M. James' stories of passion, intrigue, and betrayal will keep you hooked until the very end. If your appetite craves the intoxicating prose of Rina Kent or the allure of Sophie Lark, prepare to be entangled in M. James' captivating new series. But be warned, dear reader, for her world is not for the faint of heart. It is a world where inhibitions are shed, and inhibitions are tested. It is a world where passion reigns supreme, and where the pursuit of love can ignite a blaze that consumes all in its path.

If there’s one thing Estella has always believed, it’s that her bodyguard, Sebastian, would protect her no matter what. But when her world is turned upside down and she’s forced into a role she never wanted, one that includes marrying a stranger instead of the man she loves, everything changes. As time runs out, Estella and Sebastien finally cross the line between duty and desire, and in this forbidden love story, they’ll risk everything to be together.

“Living without you isn’t living at all.”

Deep breath, this was a high stakes book. I think I sat on the edge of my couch for the entire thing because every moment felt precious, every page felt dangerous cause while I would hope that M James is going to give us a happy ending, I really didn’t know with this one. But oh my, it was a rollercoaster ride for sure.

Sebastian Sinclair was the biggest green flag, ever. He was just so endearing, even his thoughts for Estella were almost reverent in nature, so loving and supportive in every way. It’s like her pain became his pain and I really felt like I was reading true love in it’s purest form. Estella herself was just such a sweetheart and despite being put through such a hard situation, she stayed true to what she wanted and persevered through adversity. They truly were perfect for each other!

“He’s mine and I am his, forever.”

At its core, this book is a forbidden romance between star-crossed lovers. It truly had it all…violence, high-speed chases, a disapproving parent, characters from previous books (SHOUT OUT TO ALL MY AMAZING M JAMES UNIVERSE MCS LIVING OUT THEIR HAPPY ENDINGS!) and a wild, intense love so pure you can't help but root for them to make it. I really, REALLY enjoyed this one. And while I do wish we had gotten extended future chapters, I had a blast reading it and genuinely appreciate M. James for delivering such an emotional and unforgettable story where the characters absolutely deserve their happily ever after.

Sebastian and Estella were just the most amazing couple. Even though their connection was forbidden, I loved how he was there for her when times were tough.

The only daughter to the Mafia Don, Estella is forced into a marriage she didn't want, leaving her long suffering bodyguard, Sebastian still to watch over her.

Their connection and chemistry held fast for the years they were together. He tried his hardest to remain professional, not wanting to actualise his feelings nor lead her on. But she had those feelings for him all along.

It was a tough read as the dynamic with her father putting them into that impossible situation and fighting their feelings they should act upon. The trouble that came for Estella from her marriage and after.

You can't help but be involved in the story. Wanting them to get their happy ending and be together. It was a wonderful book, full of ups and downs, drama emotions and suspense.

Well written and a fantastic plot really made this book a pleasure to read. So good!!

I love an age-gap romance. I love a bodyguard romance. I love a forbidden romance. So, this book was written for me!! It drew me in and kept me on the edge of my seat. There’s violence, action, steam, undying love and unexpected twists and turns. It’s a must-read page turner.
