I’ll admit it. I tend to be skeptical of sequels. This book made me rethink that stance.

The Serial Killer Support Network is an outstanding follow up, but it truly shines when read after the first installment. To fully appreciate the depth of this story, starting at the beginning of the series is essential.

D. B. Stephens takes the foundation built in the first book and expands it in a way that feels both thoughtful and unsettling. The story dives into the consequences of redefining justice and the system created around it. These consequences ripple across legal, moral, social, and emotional dimensions, making the narrative feel layered and complex.

About a third of the way through, I was able to anticipate some of the events that would unfold. Surprisingly, that didn’t take away from the experience. Even when I saw certain moments coming, others still caught me completely off guard. I don’t cry easily, but parts of this story genuinely hit a nerve.

What stood out most is how the book explores the tension between feeling like a victim of injustice, taking matters into one's own hands, and then facing the moral weight of those decisions. It’s not easy to separate those lines, and the story doesn’t try to simplify them.

This continues to be a perfect book club series. There is so much here to unpack and discuss, from ethical dilemmas to emotional consequences. Even if you’re not part of a book club, this is absolutely worth picking up after finishing the first book.

And honestly, I’m hoping for a third installment. There’s still more to explore, and I’m ready for it.

After flying through book one, I was really excited to jump straight into this.

And this time… things go bigger.

What started as a small support group has now turned into a full network; more people, more reach, more chaos. It’s definitely interesting to see how things evolve and how the movement grows.

That said, unfortunately, I didn’t enjoy this one as much as the first book.

The pacing felt slower, killings didn't felt as personal as in book 1 where I felt connected with the characters; for me it wasn’t as entertaining overall. I also wasn’t the biggest fan of the back-and-forth between Jess and the detective, it felt really frustrating.

The vibe felt a bit different too. Not necessarily bad, just… off compared to the first book.

Still, it’s not a bad installment by any means and I am also very curious and prepared for book 3.

⭐ 3.5 stars

Slightly drawn out overall I thought but a great continuation of the series. I really looking forward to seeing how the next one pans out. Definitely some questionable actions at times but an enjoyable thriller!

[Rustic_Reads_ Donna · Rating 4 out of 5]

Having read the first in the series ‘The Serial Killer Support Group’ I couldn’t wait to see where the story took Jess and the other members of the group. The author really hit it out the park with this sequel- shining a light on abuse, and the wider consequences of taking matters into your own hands- both for the women, the men they targeted, and the community as a whole who succumbed to mob mentality and contentious moral stances in the name of justice. I was rooting for Jess even when her choices were questionable- but I can’t say I wouldn’t have done the same if I was her! 👀

I really enjoyed delving more into Sophie’s life, her history and the lengths she’ll go to protect her family. It was also good to see the return of a familiar face, one of the few men who could be trusted.

Thank you NetGalley, HarperCollins UK and One More Chapter for this ARC in exchange for my honest review.

I thought the first book in this series was painfully average, but I got a NetGalley widget for this one, so wanted to give it a shot.

I hate to say it, but it doesn’t fare any better than its predecessor. I was bored throughout pretty much the whole book, and it required a hell of a lot of suspension of belief. The cliffhanger was decent but even that wasn’t enough to get me excited about a third book.

[Sharna Raine · Rating 4 out of 5]

I really enjoyed the first instalment of The Serial Killers’ Support Network, so I was excited to get stuck into this one, and it didn’t disappoint. It’s been great to see how the characters have developed and grown in this second book, which added more depth to the story overall.
That said, I would have liked a bit more build-up leading to Maddison’s death. She felt quite distant in this instalment, and I think more focus on her could have made that moment hit even harder.
Overall though, a strong follow-up that kept me hooked, and I’m definitely looking forward to what comes next.

[Shama Rowland · Rating 5 out of 5]

The Serial Killer Support Network… I don’t even know where to start.

This book takes everything from book one and goes darker, heavier, more emotional and I couldn’t put it down.

The character work is so layered and nothing feels surface level. It’s intense, brutal at times and genuinely hard to read in places but it feels important.

This series is doing more than telling a story. It’s eye-opening, powerful and really shines a light on injustice.

Definitely check trigger warnings but I highly recommend.

IM SORRY BUT WHY HAS IT ENDED LIKE THAT!?!????

[Sophia Scarlett · Rating 5 out of 5]

The narrative is gripping from the outset, with Jess’s journey from victim to survivor at its heart. The support group, initially a place of solace and camaraderie, quickly becomes the focal point for a series of chilling events as the ex-partners of its members begin to be attacked or murdered by a mysterious figure known as “The Caretaker.” This vigilante’s actions force Jess and the other women to confront difficult questions about justice, morality, and the failings of the legal system to protect victims of domestic abuse. 💯💓

Format: eBook (384 pages)
My Rating: ⭐⭐⭐⭐✨ (4.5/5)

Quick Take
This is exactly the kind of morally gray, high concept thriller I want, and it delivers with both meaning and momentum.

Full Review
I went into this already knowing how much The Serial Killer Support Group (first installment) stuck with me—and somehow, this sequel made it incredibly easy to fall right back into that universe. Even after more than a year, the characters, the tone, and the emotional weight all came rushing back without any hesitation, which says a lot about just how impactful that first novel truly was.

What continues to stand out most is just how intelligently constructed this story is. The concept itself is bold, and arguably a little dangerous in the wrong hands, but it's handled with the level of care that keeps it from tipping into something that feels over the top or too convenient. Even when the story sometimes stretches plausibility, it does so in a manner that feels intentional rather than forced, and that made it very easy for me to remain locked in.

The pacing here is relentless in the very best way. This is one of those books where I kept finding myself pushing for "just one more chapter," and before I knew it, I was far deeper than I planned to be in the web of the novel. It moves quickly, but never at the expense of character or clarity, which is a really appreciative balance I find in thrillers like this.

What truly elevates it, though, is the moral grayness woven throughout. This isn't a story that asks easy questions, or one that gives easy answers. Watching the support network evolve and seeing women reclaim power in ways that are both unsettling and empowering created a constant tension that kept me engaged on more than just a surface level. It's the kind of story that had me sitting with my own reactions, and I found myself fully leaning into that discomfort.

The characters are another true highlight here. Sophie Salam and Jess Pendle both stood out in different ways, but I found myself equally invested in both of their journeys.

Sophie's sharp, observant nature paired with her internal struggle to remain firmly on the side of the law added a compelling layer to the investigation side of the narrative. At the same token, Jess continues to be a powerful emotional anchor; her growth from what she endured in the frist novel to where she stands now is both steady and wholly meaningful.

Something noteworthy is this is a 4.5-star rating from me, but GR doesn't allow half-stars. That said, if I had to point anything that kept this from being a full 5-stars, it would be that the larger scope, particularly around The Caretaker's expanding influence, occasionally pulls away from the investigative thread. Notwithstanding, this never quite felt like a true negative to me, perhaps more neutral. If anything, it reinforced the core theme of the story and what it's ultimately trying to say.

By the end, I was completely invested, and more than ready for whatever comes next. If a third installment is on the horizon, D B Stephen, know that I will absolutely be first in line for it.

Would Recommend If...
I would recommend this title if you enjoy dark, addictive thrillers that lean into moral grayness and give you something to think about well beyond the final twist.

[Karen Cole · Rating 5 out of 5]

The Serial Killer Support Network is the second book in D B Stephens Secret Vigilante series; I haven't yet read The Serial Killer Support Group but although I'd definitely recommend reading the books in order because there are several mentions of events in the first novel, it didn't spoil my enjoyment of this addictive thriller at all.
The chilling opening chapter of the book introduces The Caretaker, the serial killer who has divided the nation and become admired and feared in almost equal measure. Having suddenly vanished, discussions about his identity, his work in bringing abusive men to justice and whether he will return continues. As he meticulously plans and prepares, it's clear that this last question will soon be answered – but this is a different Caretaker and this time his objectives go much further…
There are chapters interspersed throughout the book which follow The Caretaker but most of the narrative is told from Jess's perspective. Along with her friends from her support group, Kelly, Madison and Hannah, she has been changed irrevocably by all she has experienced and perpetrated but it's also clear that she is driven to protect others, and here she waits to support another victim of domestic abuse. However, as the cleverly nuanced storyline progresses, her natural empathy becomes more of a curse and there are scenes which are by turns shocking and desperately poignant.
Jess has a complicated relationship with DS Sophie Salam, the officer in charge of The Caretaker investigation. Sophie is convinced that Jess is involved somehow but under different circumstances, the two women could easily become close and in spite of the risks their friendship means for both of them, they increasingly rely on one another. Sophie will go to any lengths to protect her autistic daughter and Jess's knowledge often proves invaluable, but as her life spirals out of control, does she turn to one of her main suspects for help?
The characterisation of the two main protagonists in The Serial Killer Support Network is excellent; both are likeable, relatable characters but they are incontrovertibly flawed and are haunted by their respective pasts as events in the present become increasingly dramatic. The mirroring of their situations as they are driven to their extremes is fascinating and while there's an inevitability to their eventual paths, it's never obvious what steps they will take or what actions others will inflict to take them there.
The murders committed by The Caretaker are ruthlessly vengeful but D B Stephens' multilayered exploration of revenge and the push for lasting societal change means this is also a profoundly thought-provoking novel which will challenge the reader's own moral standpoints. With a conclusion that has left me desperate for more, The Serial Killer Support Network is a compulsively serpentine, breathlessly exciting thriller and a devastatingly moving read from start to finish. I very highly recommend it!

Review: The Serial Killer Support Network by D.B. Stephens (Secret Vigilante, Book 2)
The first rule of a successful sequel is that it must stand on its own while honoring what made its predecessor worth following. The Serial Killer Support Network manages the second more consistently than the first — and that imbalance is ultimately what keeps it from matching the tight, intimate tension of The Serial Killer Support Group.
What works best here is also what is most honest. Stephens takes seriously the question that most vigilante thrillers conveniently sidestep: what actually happens when ordinary people without training, resources, or psychological preparation take the law into their own hands? The answers are sobering and ring true. Someone becomes a copycat and gets caught. Someone else, unprepared and outmatched, pays the ultimate price — because a woman with no combat training is at a serious disadvantage against a man who isn't caught off guard. And the psychological toll of taking a life is rendered with genuine weight. One character in particular is so devastated by what she has done that the nightmares become unbearable. These are the moments where the book earns its darkness honestly.
The network premise itself is less successful. What made the original story so compelling was its intimacy — a small group of women bound by shared trauma and shared secret, a Caretaker whose identity was protected by its very containment. Scaling that into a national movement diffuses the tension rather than amplifying it, and the goal of passing domestic violence legislation, while worthy in principle, never generates the urgency the plot needs it to carry. The resolution feels convenient rather than earned.
What saves the book — and what will bring readers back for book three — is the relationship between Jess and Sophie. Their dynamic is the backbone of the story, a slow burn of mutual recognition between two women on opposite sides of a line that Sophie has been quietly crossing for some time. Sophie is the most compelling character in the series precisely because she is the most compromised — a detective who has sacrificed her integrity in increments, each transgression making the next one easier and the way back harder. Where her story goes next is genuinely the most interesting question the series has raised.
The Serial Killer Support Network is a 3.5 star book in a world that allowed half stars — better than its weakest moments suggest, not quite as strong as its best ones promise. For readers invested in Jess and Sophie, it is worth the journey. Just go in knowing that this is very much a bridge to book three rather than a destination in its own right.

★★★½

I found myself feeling quite conflicted as I finished the final pages of The Serial Killer Support Network. The premise is honestly fantastic—a movement sparked by a figure known as The Caretaker, where women across the country are inspired to take back control and seek vengeance on those who have hurt them. It’s an intriguing setup for a thriller, but I didn't realise until I was already into it that this is actually the second book in the Secret Vigilante series. While it functions well enough as a standalone, I did feel like I was missing some of the deeper motivations and relationship history that likely came from the first instalment.

The story is told through alternating perspectives, including Jess Pendal (one of "The Saved"), Detective Sophie Salam, and The Caretaker himself, with occasional interjections from an encrypted messaging platform used by the network. I think this structure was well-executed and kept the story moving, but I found the back-and-forth between Jess and Sophie really frustrating. Their interactions felt unprofessional and, at times, quite unrealistic for a lead investigator on a major case. I kept wondering when Sophie was actually going to do some real investigating, as her arc didn't seem to contribute much to the actual tension.

I also struggled with the logic of the network itself. I’m all for a story about reclaiming power, but the jump to murder for every single situation felt a bit ridiculous and bloodthirsty, especially when dealing with emotionally manipulative people rather than just physical threats. It required a massive suspension of disbelief to accept that all these women, with no background in forensics, believed they could pull off multiple murders without leaving a trace. Despite the book tackling pervasive and important issues of systemic abuse, I never quite felt that emotional connection to the characters; they just didn't inspire much confidence.

The ending was probably the most frustrating part for me. It leaves several threads dangling in a way that clearly sets up a third book, but it wasn't a satisfying conclusion on its own. I would have liked something more definitive considering how large this network had supposedly grown. I did find myself wanting to skip ahead at points just to see if the logic would eventually line up, though the twists were enough to keep me going until the end. It’s a quick, easy read that flows well, but it felt a little like a feet-dragging thriller that couldn't quite decide how grounded it wanted to be.

Thank you to the author, HarperCollins UK, One More Chapter, and NetGalley for the ARC.

The Serial Killer Support Network

An Unforgettable, Five-Star Thrill Ride!

Wow!!! Five stars from me! This novel completely blew me away. I extend my sincere gratitude to #NetGalley and the publisher for providing me with an advanced reader copy (ARC) of this extraordinary book. It was an absolutely amazing read, and I thoroughly loved every single moment of it.

Captivating from Beginning to End

From the moment I turned to page one, I was utterly absorbed in this story, and that intense focus didn't break until the very last word. The suspense was so masterfully crafted that it was genuinely impossible for me to set the book down. It became a marathon read, and I raced through the chapters, needing to know what happened next. The only downside was reaching the end—I honestly did not want this book to finish. The pacing was perfect, the tension relentless, and the narrative flow made for an irresistible reading experience.

A Cast of Characters to Root For

One of the true strengths of this novel was its characters. I loved every one of them and found myself deeply invested in their individual arcs and outcomes. The author did a phenomenal job of giving them depth and complexity, making their motivations understandable and their struggles palpable. I was actively rooting for all of them throughout the entire story, a testament to the brilliant character development.

A Brilliant and Unique Premise

The central storyline, revolving around the concept of a "Serial Killer Support Network," was brilliant and highly original. I was fascinated by the intricate details of how this network operated and the ethical and moral dilemmas it introduced. The execution of this unique premise was flawless, offering a fresh take on the thriller genre that kept me guessing.

Justice Served: A Satisfying Read

There's something inherently satisfying about a story where the 'bad guys' finally receive their just deserts, and this book delivers on that front spectacularly. Watching those who deserve retribution finally face it makes for some of the best and most cathartic reading experiences, and this novel certainly falls into that category. It’s a compelling, tense, and ultimately gratifying read that I highly recommend to anyone looking for a top-tier thriller.

[Emily Portman · Rating 5 out of 5]

The Serial Killer Support Network completely annihilated my already incredibly high expectations… it’s quickly become one of my favourites of the year so far and I just can’t stop thinking about it. I could just end my review there but there is SO much I need to say about this dark, unnerving psychological thriller.

The second book continues the story of The Serial Killer Support Group, where a mysterious someone named The Caretaker has been brutally murdering abusive men, one by one. But seeing the good work this person has done and continues to do, women across the country are inspired. So inspired that they want to take back control of their own lives, to seek revenge on those who hurt them. A new network of survivors is born… and things spiral.

The plot was strong in book one, but the author builds on it effortlessly with new characters, developed backstories, unthinkable secrets, and a continuing, solid motive for The Caretaker. He isn’t just a serial killer at this point. He’s a movement. This book is even more disturbing, unsettling and addictive than the first book. It explores the consequences of actions, and how one act can have positive and negative impacts on other people and situations. The story itself was truly exceptional, but the character development took this book to a whole new level.

The standout element for me was the development of Jess Pendle, one of the original ‘saved ones’, and DS Sophie Salam, who is working on The Caretaker killings case, their individual crumbling lives, their complex relationship with one another. The way their lives collide because of The Caretaker completely captivated me. Both of these characters have secrets they need to keep hidden away, but was there a way they could help each other? Would desperation drive them to that point? It was always tense, with a continuous sense of dread that if I’m honest, I’m still feeling now. And that cliffhanger at the end?! Holy SH*T.

If you like a dark read, you will eat this book up. If you like your Dexter-esque serial killers, this might just be your new favourite series. A masterpiece of a sequel and everything I love in a psychological thriller. I couldn’t recommend this more!

[Suesyn Zellmer · Rating 3 out of 5]

This is the second book of the Secret Vigilante series, and The Caretaker is making big news. Abusive men are being targeted to discourage their behavior and encourage legislation supporting victims of domestic violence. Until real change is enacted, he won’t stop. The more notorious he becomes, the more supporters he gains. Copycats begin to emerge, trying to hide behind the anonymity so they can seek their own revenge. But that’s counterproductive to the movement that thrives on caution and preparation. The Caretaker can’t risk accidental exposure, but that’s exactly what DS Sophie Salam is hoping for.

She’s now in charge of the investigation and at her wits' end. She’s been keeping her own secrets about the past, and now they’re threatening to be exposed. She’s terrified that her daughter is no longer safe, and between that worry and the stress of The Caretaker case, she’s exhausted and desperate. She grows closer to Jess, who is simultaneously a suspect and friend. They’re aware they’re on opposite sides of the law, but can’t break the connection they have. Which could be crucial when Sophie’s ultimate fears are realized and she needs Jess’s assistance more than ever.

Readers will know what’s coming from the get-go, as Sophie’s fears build throughout the story. She has connections to someone dangerous, and The Caretaker handles dangerous men. Pretty obvious where that will lead, but there’s a lot of buildup to that point. Most of it is frustrating to me because I honestly think the whole concept is too much. I’m all for vengeance, but it should be more relative to the crime. Man beats woman, The Caretaker beats man. But just jumping to murder for every situation is ridiculous, especially for an emotionally manipulative person. And I can’t see the public reacting like The Caretaker is an idol rather than a serial killer in this day and age. We’re a little too evolved for that anymore.

My thanks to NetGalley, HarperCollins UK, One More Chapter for the free advanced reading copy of this book.

[Carolyn Walsh · Rating 3 out of 5]

3.5 Stars. Thanks to NetGalley and the publisher for an advance copy of The Serial Killer Support Network by D.B. Stephens. I was not aware of the Secret Vigilante Series, and that this book is #2 in the series. I feel I was at a disadvantage by not reading the first book, not clearly knowing the group's background, or readily differentiating the women in the group. It was clear that their group supports victims of domestic violence in their physical and mental healing. They are reassured that they were not responsible for their abuse, and although they were blamed by their partners and subsequently blame themselves for the harm, they were not at fault. They find themselves unable to move on to new relationships because many are now distrustful of men, even when they appear kind and caring.

A force outside the support group appeared about six months earlier. They call him the Caretaker, killing the men who harmed these women. A female detective, Sophie Salem, has been investigating the Caretaker's identity and whether he has been receiving information and directions from a group member.

The premise is clever, and the story is thought-provoking, leaving the reader to ponder the morality of vigilante justice. Its narrative presents various points of view, raising issues of legal, moral, emotional, and social issues. There is unsettling ambiguity about the justification of revenge. The concept of a Caretaker is spreading from the original group throughout a network. Abused women are now acting out of vengeance against their abusers.

Recommended, but prospective readers should read The Seral Killer Support Group first. (#1 in the Secret Vigilante Series). There will be a third book to follow, and I definitely want to read it.

This is the second book in the Secret Vigilante series by DB Stephens the first one is ‘The Serial Killer Support Group’.
This is a really good follow up, I would advise you to read/listen the first book first then you fully understand the characters and what happened.

It dives into the consequences of a justice system that is failing the persons who are being abused by their spouse. So, the group/network take matters into their own hands to pass a bill called “Esmée’s law”. The main characters DS Sophie Salam and Jess Pendle are friends and are becoming closer in this sequel. But Sophie has doubts about that friendship because she suspects that Jess is THE CARETAKER. Those struggles that Sophie is feeling are well written, and you can feel it yourself. It makes her human like. Jess starts to struggle with what the Caretaker is doing after someone pretends to be the Caretaker and an innocent woman dies. Can they go on with this?

The book examines the conflict between seeing yourself as a victim of injustice and choosing to take matters into your own hands. Then dealing with: is this a good choice, dilemma.
The boundaries between those ideas are far from clear, and the story refuses to reduce them to something simple. The bourdon these killings give the “Caretaker” are well written and it makes this “Caretaker” like a real person with feelings and not just a cold-blooded killer.
When I listened to the first novel I felt torn because you want women who are being abused by their partner to be safe (in real life and in this book) in this story, but the way that it’s done isn’t the right way. But you feel compassion for this killer.
I loved listening to this book. And I highly recommend both books.
4,5 stars

The Serial Killer Support Network by D.B. Stephens (Secret Vigilante #2)

𝗤𝗨𝗜𝗖𝗞 𝗣𝗟𝗢𝗧 𝗣𝗘𝗘𝗞
Sophie Salem leads the hunt for the Caretaker, a vigilante targeting abusive men. As attacks spread and the movement grows, all signs point to Jess - but Sophie still has to prove how she’s connected.

𝗦𝗧𝗢𝗥𝗬 𝗧𝗔𝗞𝗘
I’d highly recommend reading The Serial Killer Support Group first. This isn’t a loose series - it’s a trilogy. There are repeated references back to book one and while you can follow along, it’s gonna be more enjoyable if you don’t skip ahead.

Last time, the focus was on the group. This time, it expands into a full network of women. Even so, the real heart of the story is the cat-and-mouse tension between Jess and Detective Sophie Salem.

The vibe is revenge-fueled, but not gritty. Even with the heavy topic of domestic abuse, it’s handled in a more sanitized way - light enough that it doesn’t feel completely devastating.

Fast-paced, with short chapters and multiple POVs, it’s incredibly readable and easy to binge.

I’ll be honest - this isn’t a wildly twisty ride. It leans a little predictable at times, but there’s so much to love. Women supporting women, standing up to abusive men, and reclaiming control. And that ending… chef’s kiss.

𝗪𝗢𝗥𝗧𝗛 𝗧𝗛𝗘 𝗥𝗘𝗔𝗗?
Domestic abuse fills me with a deep, dark rage - but this book caused me excitement and joy. I can’t believe I’m saying this, but I liked this even more than book one and can’t wait for the finale.

Thank you HarperCollins UK, One

[Claire Ryan · Rating 5 out of 5]

I have been eagerly awaiting this installment since I first read book one about a year ago. After the wild ride of the first book, I was worried about how a sequel could possibly live up to those expectations, especially since the mystery of The Caretaker’s identity is already resolved. I shouldn't have worried, this book is every bit as thrilling as the first, and it manages to scale the story up in a way that feels both terrifying and incredibly relevant.

In this installment, The Caretaker moves beyond local justice and takes his campaign against abusive men to a national level. His goal? To force legislative changes that protect victims of domestic abuse. It’s a fascinating, dark, and thought-provoking shift in the narrative. It is essential to read the first book before jumping into this one. This is a direct continuation of the story, and the emotional weight of the The Caretaker’s mission relies heavily on the foundation laid in book one.

While there were moments where I could tell where the storyline was inevitably heading, particularly regarding DS Sophie Salam, the journey of how we got there was so exciting that it didn't matter one bit. Stephens has a way of making the process of the hunt just as captivating as the reveals themselves. The writing style is punchy, atmospheric, and kept me hooked throughout.

The ending definitely suggests we have a third book to look forward to, which has me incredibly excited. If you love vigilante thrillers with a moral edge, you need to read this series. I adore these characters and I can’t wait for the next ride.

My thanks to NetGalley and the publisher for providing me with an ARC of this book.

Look, I loved the first book in this series. It had momentum, stakes, and a premise so deliciously twisted I couldn't look away. So when I cracked open The Serial Killer Support Network, I was ready for round two of morally gray chaos. What I got instead was... a wobble.

The biggest letdown was the character work. The newly introduced players lacked depth, making it hard to invest in their arcs or even care about their outcomes. Add to that a plot that leaned more on convenience than credibility, and the whole thing started to feel shaky. For a series built on moral tension and psychological intrigue, this installment barely scratched the surface.

Here's the kicker: the cliffhanger at the end of this book is exactly what I was expecting to get out of book two based on where book one left off. The groundwork was there. The dominoes were lined up. But instead of knocking them down, this book sort of... rearranged them. It's frustrating because I know Stephens can deliver. The bones are good. The cop's storyline hints that book three might course-correct and bring back the intensity. But after this one, I'm cautiously optimistic instead of all-in.

Would I recommend it?
If you're already invested in the series, you'll probably want to keep going, especially with that ending dangling in front of you like a carrot. But as a standalone or a sophomore effort, this one didn't hit the way I hoped. It's not bad, just... middling. And after a killer (yes, pun intended this time) first book, middling stings a little more.

[Jacquelyn Dohoney · Rating 4 out of 5]

When I first read this series, I was so impressed because I thought I had read every idea that could possibly be written. It’s hard to come up with something new and fresh nowadays it seems, and it’s equally hard for a writer to take an oft used trope like vigilantism and turn it on its head. This series does exactly that. It’s a bit like Dexter in that you know the characters are doing something awful, but you can’t help cheering them on as they do it. In this second book, it was even easier to cheer them on because I had already bonded so well with the characters. I didn’t feel as close to the newer characters though, and maybe it’s because they only appeared for a very short amount of time. But having said that, their appearances did pack a punch. (No pun intended). I did have a feeling where the story was going to go, but it still gave me horrible anxiety thinking about it. The one thing that did bother me is that a couple of character’s storylines didn’t get tied up. They were just kind of left dangling, so I’m not sure if that’s it for them or if they are going to appear in the next book. I would have liked something a bit more definitive considering how big the network has gotten. Still, I can’t wait to read the next one. If you’re looking for something along the lines of female rage, women protecting women, and women who have gotten sick and tired of being sick and tired, you will love this book!

Huge thanks to HarperCollins UK, One More Chapter | One More Chapter and NetGalley for sending me this ARC for review! All of my reviews are given honestly!

A dark and twisty sequel that keeps the momentum going

I was a massive fan of the first book in this series so I was buzzing to get my hands on an early copy of this one. D.B. Stephens has delivered another high-stakes story that keeps the tension high from the very first page.

The characters are what really make it and I especially liked getting more background on Sophie's past this time around. It added a lot of depth to her character that we didn't have before. However, I did find myself getting a bit frustrated with the constant back and forth between Sophie and Jess. It felt like it stalled the plot a little in places when I just wanted to get on with it.

One thing that didn't hit as hard for me was that the killings didn't feel quite as personal this time. We weren't as connected to the backstories or the reasons why these specific people were being targeted which took away some of the impact. The ending is also a massive cliffhanger. While it definitely makes me want to see what happens in the next instalment, it's the kind of finish that might leave you feeling a bit impatient!

Overall, it's a very good read and I'm still well and truly hooked on the Secret Vigilante series. It’s fast-paced and has plenty of surprises without ever feeling like it’s trying too hard to be shocking. If you liked the first one, you'll definitely want to pick this up to see where the group goes next.

Thanks to the author, Harper Collins UK, One More Chapter and NetGalley for enabling me to read and share my thoughts of this, the second book in the series.

In this followup to the The Serial Support Group, the women of the the group once again work to help women who are victims of domestic abuse. As noted in the title, this group is now a network, having grown to encompass more women in need and helping them get their power back.

The self named "Caretaker" continues his acts of vengeance against the bad men. Jess Pendle lhas grown from the previous book. She is more sure of herself and has become a leader for the women. Sophie Salam, the police officer, has her suspicions about the group. There is alot of gray area in this book. Is vengeance right or wrong? There is no question that what these women have had to endure is wrong. Who is the Caretaker?

Domestic violence is an emotional subject and D B Stephens takes great care in presenting the subject. This is a dark book, due to the subject matter, but it is also emotional and as a reader, I was totally invested in the stories of these women. I particularly enjoyed the relationship between Jess and Sophie and watching it change.

I will say the conclusion surprised me, but in a good way. I did not see that twist coming, but I loved it. This is a fast read, a brisk pace that keeps you wanting to see where the author goes next. I look forward to the next book.

Thank you to NetGalley and the publisher, One More Chapter, Harper Collins UK, for an ARC. The opinions in this review are my own.

D B Stephens - you absolute beauty!!!
If you derive your satisfaction from a taut, slick thriller with noir undertones and plenty of angst and tension driven chapters - this is absolutely up your alley! I read this as a standalone, but am piqued to go pick up the Serial Killer Support Group, just because.
The Caretaker is a symbol of resilience and retribution against those males whose systematic abuse - physical, mental and otherwise, brings the ladies to domestic violence programs. You have to Love strong, opinionated FMCs who are able to articulate their thoughts and rationalize their emotional and mental states - Jess and Sophie are head of the packs. Jess, coping with survivor syndrome, and Sophie reeling from past mistakes which have caught up with her.
Looming large is the caretaker, whom Jess is sworn to protect and Sophie, sworn to bring to justice - you could not ask for a better premise; with multiple chapters, the messaging and network caper are all well done, just the way I like my serial killers served. If you are looking for something to replace criminal minds as your binge watch, do pick this up - you will NOT be disappointed!
My support group extends its hearty gratitude to the sponsors of this read - Harper Collins UK, One More Chapter and Netgalley! This reader also extends her gratitude to D B Stephens for the perfect storm in a woman-centric hook! well played!

The Serial Killer Support Network is the second book from the Secret Vigilante series. Anyone who wants to read this book, needs to have read The Serial Killer Support Group first in order to really understand the story and how the group became a network.

This book shows how the network has grown and the effects of taking the Caretaker nationwide. As the Caretaker was now killing men that weren’t close to the main characters it felt that the killings were less personal. Even though the killings aren’t personal, they still have the same message women taking back their power and punishing abusers.

This book is told in three POVs Jess, Sophie and The Caretaker, which I love multi POV books, so the way the chapters are divided works very well. I really liked how this book shows how grief and traumatic events can affect different people, I thought the author did a great job showing the struggles each character dealt with, even if we don’t have their own POV we see it through the interactions.

Overall, this was a good sequel, I kept wanting to see how the story would unfold, even if I did suspect some of the things that did happen.

I cannot wait to read the next book and see how the network will keep growing, and hopefully having more Kelly and Hannah involved.

Thank you NetGalley and HarperCollins UK, One More Chapter for this ARC in exchange for an honest review.

The Serial Killer Support Network by D. B. Stephens is an incredibly strong sequel that completely changed my opinion on follow-up books. After loving The Serial Killer Support Group, I couldn’t wait to return to Jess, Sophie, and the rest of the group, and this installment delivered on every level. The story digs deeper into the emotional and moral consequences of taking justice into your own hands, exploring abuse, revenge, and mob mentality in a way that feels intense, layered, and thought-provoking. I especially loved learning more about Sophie’s past and seeing how much the characters have grown since the first book.

Even when I managed to predict a few plot points, the emotional impact never faded, and several moments still caught me completely off guard. Stephens does an excellent job creating morally gray characters you can’t help but root for, even when their choices become questionable. My only small criticism is that I would have liked a bit more development surrounding Maddison before her death, as it could have made that moment hit even harder. Overall, this was a gripping, emotional sequel that kept me hooked from start to finish, and I’m already hoping for a third book.

Special thanks to NetGalley and HarperCollins UK, One More Chapter for this advanced digital copy in exchange for an honest review.

How could this be written by a man? How could he understand what it's like to be a victim of domestic abuse? I was caught from the first page, finished in just two evenings. The book blurb didn't give anything away, hinted but nothing to spoil it. I thought a support group setting had possibilities and that's very true. I'd also never thought much about men being abused too but logically I know it's true. We call them henpecked or worse but it's assumed men can take care of themselves.

I like the idea of battered and broken women coming to life again, realizing the abuser had broken them completely down and built them back into a possession. Taking control of the situation didn't bother me nor did how they did it. I applaud the intelligent, careful, practical way the plan came together. Would I be able to do it? Yes, I feel sure I could now being older and understanding how the world works or doesn't work.

I received a complimentary copy of this book. Opinions expressed in this review are completely my own.

The Caretaker began killing bad men when women came forward to tell of the mens’ abuse. The first women were Kelly, Madison, Hannah and Jess. They formed a support group that only grew across the UK. The Caretaker is a man who prepared himself so no DNA could be found when he killed someone. Everyone involved hoped to pass legislation where men would be incarcerated if found guilty of abusing a woman. Until this was passed, the Caretaker would continue his work.

Sophie is a police detective who believes that some of the wives “saved” by the Caretaker are complicit with the crimes on abusive men. She is also a single mother whose daughter, Lottie, is autistic and she worries about her so much. Sophie has a secret from her past that she is trying to keep hidden but she is afraid it will come out that could have very bad results.

I did not read the first book in the series so I wasn’t expecting things to be so “real.” There is a lot of angst among these women and they struggle to try and lead a normal life which is very difficult for them. I found the book to be quite scary so beware if you cringe easily. All in all, a good story.
