Sins of the Father #2
Sweet Vengeance
Cillian
I can’t figure out why I’m so intrigued by Ollie Gibson.
He’s nothing like me—soft where my world is hard, sweet and kind while I’ve grown up around violence.
But there’s a fire to him that sparks the one inside me, loyalty that calls to me, and bravery I respect even if it gets him in trouble.
When Ollie’s hurt and we don’t know if the men who attacked him will come back for more, I can’t stop myself from claiming him. There’s nothing I won’t do to protect him, even go behind his back for vengeance.
I crave him—both the sweetness and the fire, the innocence and the dirty boy he turns into under my touch.
I’ll kill for him, turn my world upside down for him, share my pain and secrets with him. Ollie helps me deal with it all—even the drama with my father.
It’s supposed to be temporary. I’m not supposed to want more, but I’m determined to keep him, and for a reason I can’t understand, Ollie wants me too.
The future lawyer and the criminal. The Good Samaritan and the killer. We’re living between two worlds, this place where vengeance can be sweet and our differences don’t matter. But we both know it can’t go on like this forever. If the violence of my world doesn’t tear us apart, one day Ollie will walk away…and I don’t know how to let myself lose him.
Content Warning: Sweet Vengeance contains discussion and grief over the loss of a parent, violence, darker themes, drug use, and morally gray characters with no redemption arc. This is still a Riley Hart romance though, so you can expect a happily ever after for our guys.

Sweet Vengeance is the second entry in the Sins of the Father series, and this story features Cillian, Tiernan's right-hand man, and Ollie, Dean's former roommate. Their story is filled with possessiveness, intensity, and primal desire. Their connection is evident from the start after a terrifying incident threatens Ollie's life, which makes Cillian reevaluate his feelings and his need to protect and care for the sweet, smart, and meek Ollie.
Overall, this is a great follow-up to the previous story. It continues building on the dynamics and relationships introduced in the first story and gives you a clearer understanding of why certain characters behave and think the way they do. Ollie and Cillian share a strong connection that I enjoyed exploring.

October 9, 2025Just putting on the dnr to remind myself this one includes sharing. I greatly appreciate the author giving a heads up for that in her newsletter! And if it won't bother you, I hope you love the story.

Cillian and Ollie were so much sweeter together than I was expecting and I really enjoyed it!
It didn't feel like as much happened as in book one, but this book was only set over around three months, whereas book one spanned almost all of Dean's freshman year.
We still get the mini mob in action but this book is solely focused on Cillian and Ollie's relationship. Ollie becomes a great support for Cillian and encourages him to do things he's been avoiding, and Cillian brings Ollie out of his shell.
There isn't as much interaction with the wider group, but I adored how Rory was such a big part of the relationship too. The sharing scenes with Ollie, Cillian and Rory really emphasised the strong bonds between them and that different types of love exist.
I am excited to see who Rory is paired with though and how that will work with Cillian and Ollie too, because it feels natural that there's always going to be some degree of a poly relationship with these guys.

October 12, 2025Book 1 was 5⭐ read - this one will be no rating. It came to my attention, early on thankfully, that the "possessive MC" shares his beloved with his best friend. Nope.

Couldn’t put it down! I love this mini mob family so much. I was so excited when I found out we were getting a Cillian and Ollie story and it was even better than I hoped! I already can’t wait for Rory’s book.

"That doesn’t mean I don’t know what he does is wrong… it just means I love him more than I care about that. The future lawyer and the criminal. How will this ever work?
Sweet Vengeance is book 2 in the new, darker romance Sins of the Father series from Riley Hart and this is Cillian and Ollie's story. It's way cuter than Tiernan and Dean's relationship in book 1 Bittersweet Revenge, but there are are still some dark themes.
What To Expect:
🖤MM romance
🖤College mafia
🖤Dark themes
🖤Opposites attract
🖤Bi-awakening
🖤First times
🖤Forced proximity
🖤Morally dark grey MC
🖤HEA

So, I really can’t decide which of the books from this series I loved more. After reading the first one, I thought Tiernan and Dean would be my favorite, but after finishing this one I'm not so sure anymore 🙈
Cillian and Ollie probably altered my brain for good. Cillian is such a complex guy, I needed a minute to get him fully. He is both tender and rough, tense and relaxed, good and bad. It's like two sides of a coin. I really get it, Ollie, I do 🤭 Ollie is a sweet guy, but don't get fooled too much, he has claws, too.
This book has one bigger sharing scene with the MCs and Rory, Cillian's best friend and other half, but this is not an MMM book.
Will definitely need to re-read this book 💞

Sweet Vengeance is book two in the Sins Of The Father series. This MM mafia romance story is about Cillian and Ollie.
We first met these guys in book one with Cillian being Tiernan’s right hand man and Ollie being Dean’s roommate. This story starts with Ollie moving into a single dorm and ready to start his next year in college. When Ollie gets hurt and they don’t know if he is still in danger, Cillian steps in to protect him.
Cillian and Ollie are definitely opposites. Ollie is a future lawyer and believes in playing it safe and doing the right thing. Cillian on the other hand is a criminal who sells drugs and kills people. We see how their attraction leads to more, and in the end all that matters is how they feel for each other. Ollie feels safe with Cillian and can let go. Because of Cillian, Ollie now sees the world isn’t as strict as he wanted it to be. And while Cillian is hurt by the absence of his father and death of his mother, Ollie is there to support him and help Cillian heal.
I definitely enjoyed getting little snippets of Tiernan and Dean as well as Aislin. Rory is a great character and has a special bond with Cillian. I appreciated the content warning about the sharing scene with Cillian, Ollie and Rory. In all honesty, the sexual dynamic with the three of them wasn’t for me.
I found this story to be low angst which I thought was surprising since it was a mafia romance. And I do have to say everything seemed to work out a little too easily for me. Overall, Cillian and Ollie were sweet together and I was happy to see them get a happily ever after.

Heroes: Cillian and Ollie
I adored the relationship between Cillian and Ollie. I loved how much of a caretaker Cillian was. He truly was the most soft- and big-hearted boy. His love was so strong and obvious for everyone around him. His pain and insecurities were up front and there for anyone to see and despite trying to push away love to protect himself he actually embraced it when it came. I loved him. Ollie was sweet but snarky and extremely strong when it came to his voice and autonomy. The relationships within the group were beautiful like in book one and I loved seeing the relationships when their dads were involved.
This is an MM romance with scenes of MMM. There is violence (a physical attack on one of the MC's - not done by the other MC), m*rder, and darker themes. But there is a lot of heart, sweet moments, and soft scenes in between. Plenty of moments within the group so we get to see lots of the characters from book one. And some great steamy scenes.
I did struggle a bit with the relationship dynamics between Cillian, Ollie, and Rory. We get plenty of information that it's coming, and it's made obviously in book one as well as several times throughout this book. It just didn't quite work for me.
I have read everything Riley Hart has released and can confidently say Riley is one of my all-time favorite authors. I love the darker side with the mafia element in this series and love how it's balanced with sweet and vulnerable.

A mafioso boy and a pre law nerdy boy, opposites in every way. Yet they were attracted like magnets and kept together by a need for comfort and vengeance. Very erotic moments with many many ILUs. A pretty low angst homey book considering the world they live in.
A tame yet very sexy story.
The 'Sweet' in the title says it all.

I didn’t like this book as much as the first one (with Tiernan x Dean). Maybe it’s because this book had Cillian x Ollie, and it was the classic bad boy/experienced MMC with the good boy/virgin MMC. Ollie’s character arc took a while for the freak4freak dynamic to solidify. I didn’t mind the sharing aspect, but the repetition of “dirty boy” vs. “kitten” or “baby” during intimate scenes started to annoy me. The “mini mob” found family aspect in this universe is great though, so I’m still hopeful about the series.
October 14, 2025
Nope, this was not for me. Didn’t vibe with Killian + Ollie or their relationship. Don’t even get me started on the pet names. Sadly this was a miss.

I'm struggling to find the words to say how much I enjoyed this book.
We're back at Ashford College, where Tiernan and his best friends, Cillian and Rory, run their own side of the O'Shea family business.
The three of them are always together and they've supported each other since their childhood. Being part of such a family left scars in all of them and they've always leaned and put their trust on one another.
Cillian has a special bond with both of them: Tiernan is his cousin and the future leader of the family and their closeness has always been solid, like brothers, and he also has a very strong connection with Rory, they're like platonic soulmates. They're used to sharing everything without any jealousy, even women.
Cillian has always been curious about guys too and his curiosity is heightened when Ollie makes his appearance in their lives as Dean's (Tiernan's boyfriend) roommate.
Ollie is everything Cillian is not, he's a rule follower, he studies hard to become a lawyer, he doesn't like what Dean's new friends do. But they also have some common traits, they're both brave and loyal to the people they love, they're caring and they suffered the same pain in their young ages, when they lost their moms. Ollie has something more, though, he has a father who loves him unconditionally, while Cillian's basically avoids his own son.
When Ollie is beaten pretty badly in order to try to save an old man, the mini mob gets into protective mode and takes him under its wings (even if a little reluctantly on Tiernan's part).
Cillian, who's been attracted to Ollie for quite some time, becomes even more enthralled by him and he can't stay away from him despite knowing very well that they belong to different worlds.
I adored the development of their relationship, physically but, above all, emotionally.
Cillian is unexpectedly soft and caring, he dotes on Ollie constantly while pretending to not be in love with him. In fact he's scared after seeing what the loss of his beloved wife did to his father and how cold he became.
Ollie, instead, grew up in a loving home and when his mom died, his father kept him even closer. Ollie dreams of a love like that and he never imagined he could find it in Cillian. But the way he holds him, he cherishes him, he makes him feel safe and protected will make him fall hard.
Everyone in their review is talking about the sharing scene: I usually despite this kind of situation, where all the people involved are not committed and in love with each other.
But Riley Hart did his magic and wrote a wonderfully emotional threesome.
This part could be a little spoilery
Rory is tender and respectful with Ollie, not only because he's his best friend's boyfriend, but also because he genuinely likes him as a friend, they have their special bond when they help each other and have space to grow closer. And Cillian is not jealous of that bond, he doesn't see it like a threat, he's actually happy that they have built their own friendship and sharing his boyfriend with his best friend, for Cillian it means also sharing something special, all three of them.
One of my favourite moments is when Rory tenderly kisses Ollie and thanks him for loving Cillian.
The last chapters and the Thanksgiving scenes were also wonderful, I'm loving how all the characters' dynamic are evolving.
I'm so very curious about what will happen once Rory will have his forever love too.
I literally can't wait for the next book.

What a follow up in this new series! I get nervous whenever I love the first book as much as I did with this Sins of the Father series because it can be easy to be disappointed with the second; I am so happy that this is not the case with Sweet Vengeance! Riley Hart has once again crafted an intriguing story with beautifully flawed characters filled with witty banter and lots of spice!
While we didn’t get much time with Ollie in the first book, what we did see definitely left me wanting more! I loved getting insight into his state of mind – there is something so endearing about his protectiveness and views of how the world should work. Having him evolve, however, and not only accept but learn to love the “mini mob” was so well written.
Cillian is everything I hoped he would be and more! I love his devotion to Tiernan and Rory and the way this branched out to include Dean and eventually Ollie was quite a ride. There are a lot of nuances to his character that I was not expecting and the way he allows himself to also grow and develop with Ollie was really beautiful.
These two boys have such a special connection and what I love most is their openness with each other. There is honesty and acceptance that can be hard to find and I adore how they compliment each other!
I have loved every book I’ve read by Riley Hart and this is no exception! I am looking forward to next story in this series 😊

This book was extremely different from the first book in the series with regard to the romance, but it also followed the same lines of showing just how truly loyal and bonded this "mini mob" is. The fierceness in which anybody in their small family circle will protect not only each other, but also their chosen partners is enviable. For Ollie, who has only ever had his father as a friend in his life it's something he's never even dreamed of.
I really enjoyed seeing Cillian work through realizing he had fallen in love with Ollie. That all his blustering about not being interested in a relationship was all for nothing because he fell in love anyways. He was terrified of loving Ollie, but he was even more terrified of not having him in his life.
The spice was HOT. Cillian is a caretaker underneath his gruffer exterior both in and out of the bedroom. There was nothing Cillian liked more than giving his man what he needed. And the scenes with Rory? They added a depth that I wasn't expecting and it truly worked for these men in a beautiful way.
Though Ollie was starting to see his world shift from black and white to shades of gray, he still held onto the core of who he was. I liked that about him. He was going to need that backbone for a life with Cillian, but I have no doubt that Ollie would say the love he got in return was worth it in the end.

Omg I loved this book so very much!! Cillian was everything I didn’t know I needed and the way he fell for Ollie was just amazing! They were absolutely perfect together and the way Ollie also excepted Rory just made me swoon! Riley couldn’t have written a more perfect couple and I loved every page! I definitely recommend this one!!

Sometimes this dragged but for the most part I really enjoyed it. Ollie and Cillian are a good fit and I really like that Ollie embraced Cil and Rory’s strong connection.
Can’t wait for the next 2.

Ugh these two had me in love even before their own book!
I loved the chemistry, the characters growing and changing and how much love they shared between them all, this found family was the best thing ever.
Rory and Cillian are the best written platonic soulmates ever. You can feel that connection between them and it’s never weird or sexual, they just are themselves and love each other so deeply it feels fated.
Now Cillian with his boy Ollie was different than anything he was like before. He didn’t fully understand it, but his desire to know more about Ollie, to protect and care for him, to watch him and touch him was not something he needed to understand; Cillian just knew he wanted Ollie and nothing was going to come between that. I liked the sweet side of Cillian we got to see in this book. He was so stoic and dry in book one, but the depth of his character and his feelings was so intense and beautiful. The way he fell for Ollie was amazing and I was in love by page 20.
And Ollie? He’s my baby, the one that learnt than not everything is black and white, and that you can love someone so much it makes you change yourself because they unlock and love every part of you back. Ollie needed that. He needed Cillian accepting and being in love with ever single side Ollie showed, it made him gain more confidence (because he was already a brave little shit) and made his dream of that family/band of friends that make you feel like you have found your true identity and home.
Spoilers ahead:
I am VERY intrigued about that Rory development. He was giving me all the brat vibes and I can’t wait to read about him getting a big teddy bear of a man that keeps him grounded when needed and punishes him when he also needs it, I know it’s going to be glorious.
Riley, I absolutely love this series and I kinda wish you’d added more guys into the mini-mob so the books could keep coming, but alas, this family is perfect and you are writing an incredible story.
Thank you, TAA and Riley, for this e-arc. As you can see I couldn’t wait to read it (literally the second the book hit my kindle I was screaming lol)!
Quotes:
"You sound like you're talking to someone who's choking."
"Not yet, but you can be later if you want."
This is the first time I'm tasting him, and it goes straight to my head, making me feel drunk off him.
Deep down, I want Cillian forever.
I'm in love with Cillian O'Shea despite all the things he does, despite the fact that I just felt a gun against his body when I hugged him...and I want to be in love with him.
"Fuck, I'm never going to be able to get enough of you. I'm fucking obsessed."
There's not a force in nature that can keep my mouth from his.
"Good. I'm dying for you too. I fucking worship you. There's nothing I won't do to keep you."
"I'm not sure what I did to deserve you, but I'm going to fucking treasure you. I won't make you regret it-not any of it. We're going to have the best fucking life."
I loved the chemistry, the characters growing and changing and how much love they shared between them all, this found family was the best thing ever.
Rory and Cillian are the best written platonic soulmates ever. You can feel that connection between them and it’s never weird or sexual, they just are themselves and love each other so deeply it feels fated.
Now Cillian with his boy Ollie was different than anything he was like before. He didn’t fully understand it, but his desire to know more about Ollie, to protect and care for him, to watch him and touch him was not something he needed to understand; Cillian just knew he wanted Ollie and nothing was going to come between that. I liked the sweet side of Cillian we got to see in this book. He was so stoic and dry in book one, but the depth of his character and his feelings was so intense and beautiful. The way he fell for Ollie was amazing and I was in love by page 20.
And Ollie? He’s my baby, the one that learnt than not everything is black and white, and that you can love someone so much it makes you change yourself because they unlock and love every part of you back. Ollie needed that. He needed Cillian accepting and being in love with ever single side Ollie showed, it made him gain more confidence (because he was already a brave little shit) and made his dream of that family/band of friends that make you feel like you have found your true identity and home.
Spoilers ahead:
I am VERY intrigued about that Rory development. He was giving me all the brat vibes and I can’t wait to read about him getting a big teddy bear of a man that keeps him grounded when needed and punishes him when he also needs it, I know it’s going to be glorious.
Riley, I absolutely love this series and I kinda wish you’d added more guys into the mini-mob so the books could keep coming, but alas, this family is perfect and you are writing an incredible story.
Thank you, TAA and Riley, for this e-arc. As you can see I couldn’t wait to read it (literally the second the book hit my kindle I was screaming lol)!
Quotes:
"You sound like you're talking to someone who's choking."
"Not yet, but you can be later if you want."
This is the first time I'm tasting him, and it goes straight to my head, making me feel drunk off him.

I’d been hoping Cillian and Ollie would get their own book ever since I clocked these mofos on their first encounter in Bittersweet Revenge! This is the second book in the Sins of the Father series starring the nerdy moralist Ollie and his very own member of the mini mob, Cillian. They lived up to every expectation I had. How sweet and protective Cillian was to Ollie and how Ollie was that safe space for Cillian made my heart melt. Even though these men were complete opposites, they molded together so well and couldn’t have been a better fit.
I really loved Cillian and Ollie, but I’m gonna be honest, I didn’t live for the Rory aspect. I’m not someone who gravitates towards books with sharing partners, but I know Riley said to trust her, so I went into this with an open mind. Ultimately their dynamic wasn’t for me, and that’s ok. I adored Ollie and Rory’s friendship and how Ollie understood how important Rory was to Cillian and how much Rory cared for Ollie and took his safety very seriously. I didn’t skim any of their moments because I really did want to understand, but it just wasn’t working for me. This didn’t mean I enjoyed Cillian and Ollie's romance any less. I’m very excited to see the continuation of this series.
What to expect…
~ Found Family
~ Opposites Attract
~ Touch Him & 💀
~ Pet Names
~ Morally Gray MC
~ Close Proximity
~ Protective MC
Thank you so much for the complimentary copy 💖

Prefered this couple over Dean and Tiernan, but the plot was better in the first book. But I enjoyed this one! 😊

Review:
Sweet Vengeance, the second book in the Sins of the Father mafia series, was nothing like I expected, and I mean that in the best way. Ollie and Cillian are such a captivating mix of sweet, intense, and spicy.
On the surface, they couldn’t be more different, but together, they complement each other in ways that feel natural and inevitable. Their chemistry is heavy, yet there’s a tenderness underneath that makes every scene between them unforgettable.
Cillian is scarred by his mother’s death and his father’s absence, he doesn’t believe in love. But Ollie shows him that love doesn’t have to be pain; it can be healing, joyful, and heartwarming. Watching Cillian slowly open himself up was beautiful, and it gave the story so much emotional depth.
I also adored the group dynamics. Rory, Cillian, and Ollie created a beautiful bond, and together with Dean, Tiernan, and Aislin to the mix made it even richer. Their loyalty and care for one another made the darker mafia world feel balanced with found family love. Now, after finishing this book, I can’t wait to dive into Rory’s story, I already know it’s going to be incredible.

Overall I loved this book. I was obsessed with the first book, and I started the second right away. I loved how Cil was able to open up so much, find love, and be true to his sweet nature. Ollie was so kind, fierce, and brave. Their love story unfolded so beautifully, twisted, and a little dark at times. This is a darker book in themes, so I was expecting that. I didn’t expect Cil to be so sweet, and love Ollie so intensely.
Once I hit 80% and I entered the scene…. (Sharing) I just couldn’t get over it. I really disliked it to be honest. I think because Cil and Ollie had such a natural love, and fought for it so much not only with each other but internally it almost felt wrong? It didn’t feel romantic, or about connection, it felt so uncomfortable. I didn’t find it to be this bonding experience, or connection that was pure of friendship and love. I really wish it wasn’t apart of their story because to me personally it took away the love and intensity of Ollie and Cil. Don’t get me wrong I love Rory so much. I want him to find his happy ending. He deserves that happiness and joy so much, I just it wasn’t dependent on his best friend too. It felt forced, awkward, and co-dependent without mutual desire.
I debate on giving this at three or four and I still might go back and change it as of right now I’m leaving at a four star because up until this point I actually love this book. I devoured it I couldn’t put it down.

Beautiful. Brutal. Addictive.
I tried to stay calm while reading this book, but I failed spectacularly 😭. From page one, I was like “why couldn’t this be MMM?” the potential was THERE, the tension, the quotes, the chemistry 🫠. But as I kept reading, I started to understand why.
Not all love stories need the physical side to feel complete, and that’s exactly what Cillian and Rory have, a bond so deep, so pure, that it doesn’t need to cross that line to be powerful. And once that clicked for me, everything made sense (even if my little poly-loving heart still wishes otherwise 😅💔).
Now, about Cillian and Ollie… these two were EVERYTHING. The chaos, the violence, the tenderness hidden beneath all that danger, I was screaming, melting, and clutching my imaginary pearls more than once. The emotional intensity was unreal, and that’s exactly what Riley Hart does best: she *hurts* you in the best possible way, then gives you the sweetest healing 🥺❤️🔥
Also, that moment when everything feels perfect and calm, and you just know it’s too good to last? Yeah. I hit 79% and immediately went: “Why isn’t the book over yet?? What’s coming???” 😭
Beautiful, brutal, and emotional, this book had me questioning my morals, feeling, and falling completely for these messy, broken, lovable men. 🖤
Would I survive a reread? Probably not. Am I doing it anyway? Absolutely.

3.5/5 rounded up 4/5.
This was an interesting sequel to the Sins of the Father series. In here we have Ollie, the future lawyer and Dean’s friend, and Cillian, Tieran’s cousin and right hand.
These guys couldn’t be more different from each other, but as the story progresses, they’re attracted to each other’s personalities, which ensures an enjoyable banter. It’s almost like wanting to eat something sweet and forbidden.
Having read most of Riley’s books by now, I can see why she wanted to explore darker themes, which I think she did splendidly. Though there is an attack that provokes the urge of vengeance, we can clearly see it all comes from caring, from being protective of the people these guys feel love towards to.
I really liked Ollie and Cillian’s dynamic and how both loved their moms, how their intimacy was built on trusting each other and finding themselves in a better place emotionally and mentally. Truth is the world isn’t black and white, it’s all made of different shades of gray and whilst the world the mini-mob live in is filled with live-or-die situations, they do have a moral compass.
My favorite part of this series is undoubtedly the found family, our dearest mini-mob. I love how each and every single one of them would do anything for their group and how loyal they prove to be time and time again. Their bond is strong and despite their different takes on life, they do respect and honor each other.
Also, I think the shared scene was so important to the three of them and it truly reinforced their bond –sometimes there are no words to explain, things just are.
Last but not least, I’m eager to read the last book in the series, which I’m curious about since Rory will be the MC. Who would have the guts to manage our wild boy?

This is book two in the Sins of the Father series featuring Cillian and Ollie. Cillian is Tiernan's cousin and right-hand man and Ollie was Dean's roommate last year. I was surprised by the pairing of these two, but, OMG, it worked.
In the first book, Cillian was only with women. He and his best friend, Rory, made comments about being interested in men, but I wasn't sure how it was going to work. Cillian is just wonderful with Ollie: protective, caring and sweet. When Ollie is attacked, Cillian and his crew are there to protect and take care of Ollie. I love how different the two men were. Ollie wants to be a lawyer and is with someone who breaks the law regularly, but they also have things in common. (family history)
There isn't as much of the other friends in this story, except for Rory. He is Cillian's best friend. The sharing scene with the three men emphasized the special bond that Cillian has with Rory, even though it's not a sexual love.
I am looking forward to Rory's book next and to see who he is paired with and how, if anything, it affects the dynamic with Cillian.
