4.5⭐️ I absolutely ate this book up! I love a mafia romance with spice and this delivers, holy smokes!  Every single couple and group scene was hot AF and I loved it!  It is very clear how much love and support the main characters have for each other, and I love how well they all mesh together!  I can't even choose a favorite character because I love them all for different reasons!  

It does end on a cliffhanger and now I'm dying for the next book!

What To Expect:
💜MMMFFF polyamorous relationship
🖤Dark Mafia Romance
💜Bi-Representation
🖤S** Club/Masquerade Fun

I got the chance to beta-read this for Bri and whew! This left me hot, heartbroken, and wanting more. B.B. Heron’s pen game for these spice scenes was amazing. For so many damn bodies she made it work 😂I love how the core four felt an instant connection with Sonny and Willow. They were all made for each other and it was beautiful watching their love for each other grow throughout the book. It was great seeing Sonny grow into himself and out of what his father wanted him to be. I love how Willow met her match with everyone. She’s such a healer and lover girl that the relationships she has with each of them are perfect. I feel like I see so much of myself in Isabella’s personality that she might be my favorite girl ♥️ She is so strong and I was so proud of her throughout the story. Catalina is such a badass, sarcastic little devil! When it comes to the people she loves, she does not play!!! Dario, being the boss, felt like everything was on his shoulders and my heart couldn't break more for him. I'm glad he has everyone to help him through it, keep him grounded, and show him love. Niccolo omg 🥺 my baby. I love him bad. I can't even get into my feelings about him or I'm gonna spoil the whole book 😂 Anywaysss, these are all such amazing characters, even the side characters were lovable. I’m excited but also nervous as hell for the next installment. I know it’s gonna be great but I hope it doesn't rip my heart in two 😂

It took me a couple days to gather my thoughts. Although I did enjoy this book I wasn’t a huge fan of the instant love that happened when they added the new couple into their relationship. This book is also heavy on the spice, so it really seems like that is all going on at some parts. I still would recommend this book because over all I did enjoy it!

Thank you to the author for letting read an ARC copy!

God damn that was hot 🥵 and that cliffy was so mean 😭

I loveeee the bisexual rep in this book. It’s soooo hard to find bisexual rep in FMCs and I really appreciated it reading this!

There was definitely a few twists I definitely did not see coming that kept me from putting the book down!

P.S. charge your vibes 🥵

I got this book as an ARC. I devoured this mafia romance in one sitting. The spicy scene were EXTRA spicy 🌶️

[Brittany Thomas · Rating 5 out of 5]

Omg what a spicy and incredible poly fam mafia read!!
I ate this up!!!! It was beautifully packed with all my favorite tropes!! Mmmfff 🔥🔥🔥 taboo mafia dark romance allllll the ones that leave me panting.

There’s one way to join mafia forces this group definitely got creative!

The spice was so damn spicy but the plot flowed fantastic and I was hooked from the very first page!

The ending was cruel leaving us on a cliff hanger, like audibly screamed!

[Tyler Markham · Rating 5 out of 5]

This was a wild one and I loved every second of it. The characters are instant loves of mine and making the women so bad*ss is always a way to make me love a book plus the d***y kink another way to make me love a book. The plot didn’t take away from the spice and each character was able to show their personality without it seeming like repeat personalities which I have seen in other books with so many people in relationships but B.B. found a way to give each person their own vibe and personality. My review is kind of short on this one only because I’m in the process of rereading it to fully get everything going on. There was a lot of people to keep track of so I’m wanting to make sure I didn’t miss anyone or anything. It is a shorter read so that helps with rereading. I can honestly say that Miss B.B. does not and has not missed with her books so far and I can not wait to see what else she has in store for us

4.5 starssssss

Whew, I am drooling all over again writing this review. Let me tell you if you enjoy a variety of spice B.B. Heron and her filthy characters belong on your TBR.

One of the things I love about B.B.'s writing is that you never feel like any particular character or couple gets the short end of the stick. You are able to build an investment in the success of the group relationship and swoon with each delicious scene. How she manages to accomplish it with 6 personalities to keep track of, i haven't the slightest clue, but I am in awe of it.

Being a mafia romance with all these moving parts, you may be worried the plot is lacking but have no fear B.B. has got you covered there, too. Ending on a cliffhanger, I will be left with my jaw dropped waiting for book 2.

[Tara Ptack · Rating 4 out of 5]

Heartless Mercy by B.B. Heron is the perfect spicy mafia book! It features everything you might want, or didn’t know you wanted 😏

This book was well written and sometimes feels like you’re in the story with them. You’ll be able to watch all the characters love bloom between one another while they try to manage their family businesses. It all comes together like the perfect puzzle!

The ending will leave you literally gutted with the cliffhanger, but it’ll make sure you read the next book!

As always, check your trigger warnings before you read! Your mental health matters!

Delicious

Mexican mafia for the win! This was such a great book full of good plot and even better group relationship moments. The love with this group was so hawt and intense and heart touching. Plus all the representation and truths in this really speak volumes. I can wait to see what happens next! My jaw was on the floor with that ending!

[Amoyisreadingxoxo · Rating 5 out of 5]

B. B., Bri, Ms. Heron!! I-
These characters are the best combo, and I was LIVING my best life in every group scene🙂‍↕️

Sonny, Willow, Isabella, Catalina, Dario, and Niccolo are a tribe that I THOROUGHLY enjoyed reading about. I loved how each couple had their dynamic and relationship solidified, that and as everyone mingled you saw all the different sparks. Everyone brought so many different qualities to the relationship, and I think that was definitely my favorite part overall. Dario being the center of everything makes me so happy, and I’m glad he has support outside from his mafia world🥹

The spicy scenes in this will make you SWEAT, too good🫠🖤

[turnthepaigealready · Rating 3 out of 5]

Who doesn’t love a spiccyyy mafia read. This book is fast paced, action packed. The MMMFFFs are to die for, a beautiful relationship that grows and understands.

Powerful FMCS, strong, badass, almost knock you off your feet kinda way.

The MMCS are captivating, hardcore yet soft and oh so sweet.

Seems like we have some twists to find out, who doesn’t love a good cliffhanger

Spice 🌶️🌶️🌶️🌶️

Mafia meets polyamory in this awesome book of sexy suspense! However BB that ending I am gutted!!!

This a mafia book of romance and being your true self. Dario and Niccolo are in a relationship as are Catalina and Isabella. They have decided to share their love together. But then they meet Sonny and Willow and they feel the connection again.

But Dario, Niccolo, Catalina and Isabella are all tied to the mafia and things are brewing that could make their relationship even harder. Mafia means blood and war.

This book was so well done a mix of plot and spice. And I need to know what is next NOW! I see many families we can follow in this series too! I love that l.

This was an arc read Thank you so much B.B.Heron for letting me be apart of it.

This book was amazing I enjoyed every minute of it. I love a good mafia book! My favorite male was Dario him give off those “Daddy vibes” and being a dominant type🥵 my favorite female was Catalina she was really crazy and ready to kill for the ones she loved and she made me laugh when she would mess with Niccolo. This had the right amount of spicy, I can’t wait to see what’s in store for the next book!

[A. Miri · Rating 5 out of 5]

From page one i was sucked in. BB did such a good job giving each character their own personalities without it feeling cramped. The chemistry between each of them is wonderful and I can't wait for more. Also noticed the nod to another author and how this is a cross over. Absolutely amazing 5/5 stars

[Leona Pilbeam · Rating 4 out of 5]

I enjoyed this book. I think that maybe there should have been a bit more of a focus on the storyline as at certain parts of the book, it was nothing but spice. That's why I haven't given 5 stars sadly.
It ends on a massive cliffhanger that I didn't see coming and I can't wait to see what happens next.
Please make sure to check for trigger warnings .

This book, I have no words for it! It was soo freaking amazing, the spice was too much spicying and the plot and the romance and the group scenes!!! Everything was super hot and the cutest of Nicknames 🥹🥹🥹💖💖
And the ending left me needing more!!! I loved this book soo freaking much and I crave to know what happens in the next book❤️‍🔥❤️‍🔥

I love that this wasn't just Italian Mafia but it was Mexican Cartel also, I also love the poly rep, this is such a good book and it's definitely got 5🌶️ spice. I absolutely recommend this book but don't forget to check your trigger warnings

The cliff hanger Bri leaves us on in this is not okay! I need book 2 ASAP ma'am😂

This was so hot, I loved that you got Bi rep from all of the main characters. She gave us spice when we needed it the most, heartbreak when we didn't want it, but it made the plot so good.
Watching Catalina, Dario, Niccolo, and Isabella all fall for Sonny and Willow pretty much instantly was beautiful.

[Katia Roman · Rating 5 out of 5]

Ok guys… I didn’t think I’d like an mmmfff poly why-choose but damn it BB made it work! I absolutely loved it!!
Mafia as background story and it had suspense that kept me on the edge of my seat. And the spice?? Oh my god the spice is top tier!!!
The cliffhanger made me cry and I can’t wait for the next book!! B.B. Heron is a new author that is worth looking out for!!
Highly recommend ❤️🌶️🌶️🌶️🌶️🌶️

If you love spicy Mafia romances then you need to read this!!! Polyamorous relationships, fast-paced and action-packed.. the spicy group scenes are smoking hot... and that ending nearly killed me off.. can't wait for the next one to know what happens.

DNF - 53%

I really loved the beginning of this book. I saw some comments about how there was no translations and I agree it would have been nice to get them but I also can infer what was being said from the surrounding conversations. Now my reason for DNFing has some parts.
1. I loved the idea of it being poly but it felt weird to me that it was couples if that makes sense, maybe because I'm used to just single people but I couldn't help but think that there would be favoritism even with them all being into each other.
2. This goes with this but the pacing of this book was so fast that I felt like I couldn't even get into the story. I just realized it was 285 pages and it was over the course of i think like 4 days at 53% but they're already like poly... i don't know the word for how many people but more than a cube. I felt like I got whiplash from how fast it went and how much happened. A person is being killed, then being put on leave to deal with the death and now we're at a casino with the people we met 2-3 nights ago getting sorta threatened by a random. It was just a lot and then add in the mafia aspect and how everyone is tied together, I needed a chart or something.
There is definitely a possibility I go back and try it again, maybe it's me. Like I said I really liked the beginning i just felt like it was that test in school where you have to run and get to the line before the beep and I slowly stopped being able to get to the line.

This is my first book by this author and definitely not my last one. I loved how each chapter had a song name attached to it & one of my favorites was titled Close. If you enjoy a book with spice, boy let me tell you how worth it is to pick up this book. This book represents a polyamorous relationship and has so many other tropes that one will enjoy. The cliffhanger at the end blew my mind and left me wanting so much more from the author.

Rating: 4⭐️/5

“I’ve been told I’m a lover girl. The possibility of having a relationship with not only one, but five other people is wild. But I won’t close myself off from this opportunity yo find something deeper with someone or multiple someones.”

HEARTLESS MERCY is a fast-paced, action-packed mafia romance brimming with danger, passion, and drama. As Dario takes charge of the Mexican Cartel, he seeks guidance from Niccolo, the Italian Mafia boss. Their alliance becomes complicated by tangled MMMFFF relationships with Catalina, Isabella, Willow, and Sonny, creating a story filled with tension, betrayal, and forbidden love.

The FMCs are fierce and unforgettable—Catalina stood out as my favorite with her unhinged loyalty and dark humor that added much-needed levity to the chaos. On the other hand, the MMCs are equal parts commanding and tender. Dario exudes “Daddy vibes,” with a dominant and protective nature that makes him a captivating lead. Together, they create a blend of fiery chemistry and emotional depth that carries the story even through its most intense moments.

While the spice is off the charts, I do wish there had been a stronger balance between romance and plot, as some parts leaned more heavily into steamy scenes than storytelling. That said, the explosive cliffhanger at the end left me desperate for the next installment. This book is perfect for readers craving a fast-paced, spicy romance with unforgettable characters—just make sure to check the trigger warnings before diving in!

A big thanks to B. B. Heron for sending me a digital ARC of this book!

This is a scorching, suspenseful read that left me heartbroken and yet craving more.

The spice in this book is hoooooooot, and the MMMFFF relationship dynamics within these pages blew my expectations out of the water! Watching the love blossom between Sonny, Willow, and the "core four"—Dario, Niccolo, Catalina, and Isabella—was beautifully done. Each character brought something special, and even the side characters were memorable.

I especially loved seeing Sonny’s growth and Willow’s healing energy, and I saw parts of myself in Isabella’s strength and Catalina’s fierce loyalty and sarcasm. Niccolo and Dario were both deeply compelling (i cannot telll you the love i have for my new BF Niccolo!), although, I do wish Dario and Catalina’s connection had been explored a bit more, maybe in the next book?

The mix of mafia action, romance, and complex relationships was well balanced, but the cliffhanger ending has left me gutted.....Why you gotta do me like that B.B?!
I can’t wait for the next installment—this series has so much potential!

[Kylee · Rating 5 out of 5]

Wow! I really loved this book! So different yet so good. It was suspenseful yet I was craving so much more by the end. I loved everything from the plot to the characters. Everything was unique and so well written. I was able to imagine this world so well.

These characters were all so amazing! They blew my expectations away. The dynamics in the relationships were very good! I loved watch the love blossom between the characters. Each one brought something to the relationship that was needed. Like a puzzle piece the comes together so well! They are all so memorable.

While I love the sweet moments and the passion in this book, I will say I definitely enjoyed the spicy moments too. There are some very hot hot moments in this book, and that’s always a plus for me lol.

Overall, I absolutely enjoyed this book and the dynamics between the characters! But I do have to say that cliffhanger!! It definitely left me hanging and I’m so excited to see what happens in the next book! I highly recommend this book! So good!

Heartless Mercy left me hot, heartbroken, and wanting more and let me tell you, the spice throughout the book is REAL 🌶️🌶️🌶️🌶️🌶️

This was the first book I have read where it was a mmmfff polyamorous relationship and I didn't know what to expect but I can tell you if I had expectations they would have been blown out of the water. I absolutely devoured it and loved it!

Watching the love story bloom between the group was beautiful. My only disappointment and the reason for the 4-star review is because I was hoping that we would get to experience Dario and Catalina explore their connection beyond their friendship. It felt like everyone else explored something deeper except for those two so I felt like they were kind of forgotten and it left me feeling some type of way.

That ending though and the cliff hanger 🥺.

I can't wait for the next book and to continue the series.
