Merciless Union: A Dark Mafia Arranged Marriage Romance (Blood and Thorns Book 2) Kindle Edition
Skeletons fall out of the closet as I get my memories back.
Everything changed overnight.
Truth became my enemy, and the sting of betrayal dragged me into a web of lies.
I’m damned if I fight to live and damned if I die.
The dark secrets I remember might tear my marriage apart.
Love is a myth we shouldn’t have explored.
My husband was always my enemy.
Love just made me forget and blinded me.
The cruel hand of death is the only answer when doom takes over.
I don’t know if I’ll survive.
Or if death will bury me along with the sins of my father.
Merciless Union is a dark mafia arranged marriage romance. It contains dubious situations, mature content, and graphic violence some readers might find offensive and/or triggering.
This is the last part of a duet and is not standalone.

- Reviewed in the United States on January 11, 2022Merciless Union: A Dark Mafia Arranged Marriage Romance (Blood and Thorns Duet Book 2) by Faith Summers is a sweepingly dramatic conclusion of Aria and Lucca's love story. Blood and Thorns is a fitting description as blood is life and thorns hurt. There is so much hurt and darkness in their lives, from their individual youths to the present, together and apart. But because of their heartfelt and precious beginning as children, you can't help but hope for this love to surpass any and all obstacles.
As one would expect from a dark, mafia world romance, the plot places each of them in peril (repeated) and the vile evilness that surrounds them is a constant presence that suffocates and blankets every good thing with danger lingering in the air. This book was a page turner as little nuggets of revelations are spread throughout. With each new revelation, I was simply compelled to continue to see what Lucca and Aria would do or what evil antagonism would befall them next. It's a constant back and forth giving the reader that sense of just waiting for the other shoe to drop and put our hero and heroine in peril once again. But it's not only their dark world, the mafia elements and danger that make this such a compelling read. Aria's amnesia, the forced marriage, trauma from her childhood and coming to terms with what she should want and what her heart wants is just the tip of the ice berg. In addition to the action, the steamy interludes with Lucca, there is a deeply emotional and psychological aspect as well. And it's not just Aria that goes through it. Lucca has his own deeply disturbing emotional and psychological issues to deal with both past and newly present.
While the dark romance elements and the mafia world make this book intriguing, the characters make it exceptional.
Overall, Lucca and Aria are stronger together and prevail against all the odds. Their love shines through giving them the impetus to survive. Not only do they survive, but Aria thrives and Lucca basks in the glow of his, Aria's and their family's HEA.
- Reviewed in the United States on May 24, 2024I love to read stories that stay with me for years and this is one of those. There is so much intrigue in this series you’ll never guess what will happen next. The characters are so different, with the hurts piled on to their lives. Please don’t miss this series. You’ll be glad you didn’t.
- Reviewed in the United States on August 12, 2021For honest Review I love merciless vow so I got the second book its the same story so I'll give it a 10 star for the story but was disappointed because I thought it was a different story . if you have not read merciless vow this is my Review Wow fantastic job 10 stars this story has love , friendship ,betrayal , action ,and so much more . two young. Children arie and Luca were Peter pan and Wendy in wonderland ,but with his family being murdered and her with betrayal in the worse kind and amnesia because of it, and love lost .now older and back together they are trying to put all the pieces together to find out all the lies, secrets ,and more as they figure out the puzzle to it all .
- Reviewed in the United States on May 8, 2024Absolutely loved it. And book 1. Lots of mystery to follow and figure out. Surprises. Suspense. Great book! Highly recommend
- Reviewed in the United States on June 24, 2024I was freaked out this whole book cause I just wanted lucca and aria to survive everything and get through it and build their relationship.
This was full of romance action heartbreak my goodness.
Absolutely deserves 5 stars
- Reviewed in the United States on January 27, 2024This 2 part series had me in a CHOKE HOLD. I read all 900 pages in like 3 days. So many twists and turns my heart couldn't keep up. HEA but please note big TW like child seggsual abu$e and explicit torture like scenes.
The story was just well written and while I normally like my FMC to be a bit more feisty you'll understand why she is the way she is. And we love a man who reunites with his childhood love ❤️
- Reviewed in the United States on April 24, 2023I am so happy I continued reading this story. It was SO good. By the end of it I wanted to murder a few people myself. And what I feared that I suspected when I first started reading the story proved true in this book. How disappointing. Thank goodness Lucca and Aria loved each other since kids or they may not have survived this. I’m already hunting for my next book by these two. And I’ve already read so many of them….
- Reviewed in the United States on October 20, 2024This was a good story, but I it kind of dragged out in this 2nd book. The first book was very interesting though.

5.0 out of 5 stars Such a Thrilling and Twisted Read!
After the amazing revelation the first book in the Blood and Thorns Duet was for me, I couldn’t wait to continue Lucca and Aria’s journey in Merciless Union. This second installment was simply electrifying! I loved every single instant of my read, packed with outrageous disclosures, sinfully hot encounters, profound feelings and it had adrenaline coursing through my veins from all the action. I was appalled at some deeply disturbing secrets unveiled and swooned over the evolution of Lucca and Aria’s romance that got truly breathtaking. This world of violence, corruption and depravity was utterly mesmerizing with its sparks of light, hope and devotion. Faith Summers is an author I look forward to reading more of her backlist novels. This duet was simply magnetic on all levels!

4.0 out of 5 stars What an ending to the duet
A masterful ending to the duet. This story is heart breaking. It will break your heart, mend it and then break it again. The suspense in this book is so intense and we'll written that it gets hard to leave the book. My heart goes out to the two protagonists, Lucca and Aria. Both have gone through soo much already, but the things that unravel in this book are just insane and I have no idea how someone survives these secrets unravelling. They are super strong characters with loads of emotional baggage and trauma attached to their childhood and adult life.
Some elements of the story revolve around sexual child abuse. This part really made me uncomfortable. Faith summers doesn't really cover the brutality of abuse. She writes it the way it should be written. This can also be a trigger for some.
The one part that affects my rating is that I somewhere was able to predict the ending, as in who did it. And it wasn't really a surprise for me.
However, this book is super well written, with an epic cast of characters who are morally grey. All mafia romance lovers should pick this duet up. It will be worth your time for sure.
