Three sisters, one of them is secretly a serial killer. But, which one of them is it? Dark pasts, gritty details, nightmares, and untold secrets bind these three together leading to the untold presence where the police are now involved.

Thank you, Netgalley, KD Aldyn, and Poisoned Pen Press for the ARC of ¨Sister Butcher Sister.¨ I was intrigued by the description of the book, so that is what caught my eye - but then I was thrown head first into a novel with gruesome and descriptive events that are not suitable for children... or some adults! I definitely recommend reading the trigger warnings before reading. However, I did find the dialogue between the sisters to be humorous, and their backstories evoke different emotions which the reader can be empathetic to. The author has a way of pulling at your heart strings in a way that the reader can connect to the sisters on an emotional level; and all of a sudden the reader... like watching a horror movie... is reading the next chapter behind their fingers covering their eyes. This book is not for the faint of heart! But if you like books with themes of family drama, trauma, and also gore - I think this book is for you!

This book has a fascinating concept and decent execution. I was intrigued by the Rowling sisters - each damaged, and a little twisted in their own way - but I did find the characters stiff and overly formal. The sections from the killer's point of view are brutal and gory, not for the faint of heart! And the mystery of the killer's identity is was incredibly entertaining. There's an atmosphere of unease and discomfort here that's hard to shake.

Thanks to NetGalley and the publisher for this ARC!

Dark. Disturbing. macabre.

This book sinks its teeth into you with quiet horror, unraveling in a way that’s both unsettling and strangely captivating. It’s not your typical gore-fest—it’s psychological, tense, and full of slow-burning dread that crawls under your skin.

The writing is gritty, the tone is haunting, and the atmosphere feels like walking through a nightmare you can’t wake up from. It lingers—in a good way and a very creepy way.

Perfect for readers who crave something weird, dark, and a little off-kilter.
My rating would actually 3.5

Sister Butcher Sister is about 3 sisters. One is returning home to buy their late grandfather's house, the sister that appears to have her life together but is actually having an affair, the sister who was a whole disaster and got into all kinds of trouble, and then the mysterious "she" that is going around killing specifically men. You have no idea which sister is the killer until the end.

This book has an intriguing premise. I spent the entire book trying to figure out which sister was the one going around killing men. Even tho I had it right, every time the POV swapped I started doubting I was correct. In the end I was right, but I questioned it continuously! Although the sisters' backstories are sad, it was really interesting learning about them and why they turned out the way they did. The backstories also cause you to have empathy as to why the one sister decided to start taking out the human male species.

It was easy to read. Although there were several POVs, I was able to easily keep up.

I gave this book 4 out of 5 stars and recommend it to anybody who likes a good "whodunnit."

'Sister, Butcher, Sister' by KD Aldyn had the makings of a gripping story, with a plot that promised intrigue and emotional depth. Unfortunately, the execution fell flat. The pacing was sluggish, and the writing lacked the energy needed to bring the narrative to life. Despite the story’s potential, it often felt drab and uninspired, with characters who never quite felt real. Moments that should have been tense or moving came across as oddly muted. It’s frustrating, because the premise is genuinely interesting—but the delivery left me disengaged. A missed opportunity for what could have been a compelling read.

I feel like I say this for every thriller I’ve read recently, BUT THIS WAS SOOOO GOOD! The plot was so good. The writing style was my fav: short chapters that keep you hooked, AKA crack format! The twist had my jaw on the floor my lanta!

This book is a wild ride! Dark secrets, brutal revenge, and a mystery that will keep you guessing until the very end. The story switches between three sisters – each with their own secrets – and the short chapters keep you completely hooked. It's fast-paced and intense, with some seriously shocking twists. Highly recommend! Thanks to Poisoned Pen Press and NetGalley for the ARC to read and review.

Sister Butcher Sister was a wild ride from start to finish. At different points in the book you feel deep empathy for each sister, then almost immediately after you feel suspicious of each one of them as well. The first half of this book is a little bit slower, but it really picks up at the end. Three sisters, all with deep and dark secrets that they can’t even fully remember - and one of them is a serial killer. But which sister is it?

I really liked the addition of the “She” perspective in this book. I feel like it helped me as a reader see how unhinged the killer was becoming without ruining the plot twist of which sister is the serial killer. I found myself sucked into this story, and wanted to drop everything else to read it and find out who was behind the murders.

Thank you to KD Aldyn, NetGalley, and Poisoned Pen Press for an eARC of Sister Butcher Sister in exchange for an honest review.

Sisters. There were never such devoted sisters.....

This is no Rosemary Clooney.

Kate, Aurora and Peggy are sisters. As expected, they don't always get along. They have their families, and secrets and shared history. Also, Aurora will NEVER forgive Peggy for what she did.

Also, one of them is possibly a serial killer.

There's a ton of potential with a storyline like this. Family history is always a gold mine for trauma, and this family was not different. I do feel that KD Aldyn is a good writer, was got a bit bogged down with the details, and sometimes the whole point is missing. This is a very wordy book and editing could help the flow and timeline of the story.

Thank you to NetGalley and the publishers for the opportunity to read and review this book.

Sister, Butcher, Sister is a pitch-black thriller that descends into the complexities of life after severe trauma.

The POVs of three sisters and an ominous "She" serial killer unfurl the story of the Rowling sisters. When the oldest sister returns to her grandpa's home to purchase it, unsettling memories of the past shake up her and both her sister's worlds. The reader is left wondering what really happened to them all growing up, and how will that affect their lives moving forward?

If you love intensely dark, harrowing stories about complex and toxic family dynamics, this one is for you!

What a dark, twisty read! Sister, Butcher, Sister is such a multi-layered story that kept me guessing. I really enjoyed that it started with a look into the killers mind and then turned into a mystery, yet still managed to keep the intrusive thoughts and the wild actions of the killer woven in. The unreliable narrator being the unknown killer was also a nice touch.

I loved how seamlessly KD Aldyn switched from first person to third person, I feel like that’s a special skill, often done poorly - so bravo!

Overall, I really enjoyed the book, although there were times it dragged on.

I got this book as an eARC from Netgalley and Poisoned Pen Press and I was so excited after reading about it and requesting it. The books follows three sisters, each going through their own lives and struggles. We also have a fourth perspective of She - a murderess taking some vengeance on men.

Lets discuss why I gave it the star rating I did. One of the biggest things I reminded myself of multiple times is that this is a debut novel, and I have every indication within the pages that the author will end up being fantastic and so I do feel guilty giving this one a lower rating. The writing is good on a technical level, and I think it takes skill to switch between third person and first person within the four POVs and have it be as seamless as it is. This is skillful, and something I don't see done often and was impressed with it.

As we are following three sisters, we see their indivual struggles. There is some discussion about motherhood as we have one married mother, one single mother, and one child free sister. Kate is a classic "child free high career earning" lady who is obsessed with their grandfathers old house and has returned home after purchasing it. She is the oldest of the group, but has ahabit of running away from her problems and not wanting many strings attached.

Aurora is the middle sister, and married with two children. She plays the harp, and has always been the care taker "good girl" of the group. If you were to lift her from being the middle child and make her the eldest and asked to describe a "classic eldest daughter from a drama" you'd be spot on. Her biggest twist for most of the book is simply that she's the middle sister.

My favourite to follow was Peggy, the youngest and wayward daughter who is a "trainwreck" and is trying to be better for her son and working through demons of addiction and alcohol.

I really think this author has talent and technical proficiency, and I'm looking forward to trying their next work. This one did not land for me. It was slower than I was hoping, and most of what I read from one POV (I won't say which as I do hope others go into this and enjoy it) was dull and unnecessary as it was also discussed by the other sisters. I struggled to turn the pages with the pacing, likely because I believed what I was getting was a thriller. This book leans on "dark women's fiction" in the beginning and as we continue on takes on more and more of a "character led detective drama" feel. This isn't bad, but it wasn't what I was expecting and it threw me for a bit.

Check your trigger warnings. I hope the finished novel has a list at the front or the back for readers.

I like the cover of this book, I found it intriguing. To start off, I want to say that I loved how many POVs were in this book. I sometimes have a hard time paying attention (I have bad ADHD), so the change of POVs kept me on track and reading. I did find parts of this book predictable, but getting to that point was a good read. I don’t think my prediction being right took away from the book at all. The book was very interesting, I liked reading about the sisters problems and past. Definitely a good read and worth the read.

The premise had promise—three sisters, one harboring a killer—but the execution didn’t work for me. The multiple POVs made it hard to connect with any one character, and the constant perspective shifts felt more disorienting than suspenseful. While the story leans into dark family secrets and buried trauma, the narrative felt scattered, and the tension never fully landed.

Sister, Butcher, Sister follows two sisters raised in an isolated, violent community where loyalty is demanded and questioning the rules is dangerous. When one escapes and the other stays, their lives split in drastically different directions—but their connection never fully breaks.

The book is unsettling and intense, with moments of real emotional weight. It doesn’t shy away from brutality, but nothing feels gratuitous—it’s all tightly written and purposeful. The sister dynamic is complex and believable, and the story unfolds in a way that feels both grounded and haunting.

A bold, unsettling read that stays with you.

The plot is unique and intriguing. The story is told from 4 different POVs. We hear from each sister and the "she" who is the killer that we are trying to figure out. With a difficult childhood and deep traumas, each sister could easily have a reason why they would be the serial killer. Without giving anything away, I was able to guess who it was based on certain things said. However, I still enjoyed reading this thriller about the three sisters.

Thanks to NetGalley and Poisoned Pen Press for a digital ARC in exchange for my honest review.

At first, I found this story difficult to get into, but when I did, I couldn't put it down. I love how it was structured, switching between 3 sisters - Kate, Aurora and Peggy - and a mystery perspective of one sister who happens to also be a serial killer. Aldyn does a really good job at making all narrators unreliable and suspicious by stacking evidence against all of them. I was still wavering between 2 options up until about the last 40 pages. I also ended up feeling a lot of sympathy for the killer. As we learn about their lives, we also learn about their disturbing childhood and strange parents. TW: this book talks about murder graphically, SA of children, r**e cases.

I would've liked more explanation into Aurora's breakdown, to see more of her psychology like we did with Peggy. I thought the ending was so sudden.

WOW! This was so dark and twisty and disturbing. Major props to KD Aldyn as I did not know which sister was "The butcher" until the very end and I couldn't have guessed correctly if I wanted to. this was so immersive and hard to put down, I binged it in 24 hours.

All I can say is WOW—this is hands down my favorite read of 2025 so far.

KD Aldyn masterfully weaves together the POVs of three sisters while steadily building tension throughout. The transitions between narrators were smooth and never confusing, and the plot twists? Absolutely incredible.

One of the most impressive aspects was how the killer’s voice felt so distinct and separate from the others—it kept me guessing the entire time. I was constantly torn between suspects, and somehow, Aldyn even had me rooting for the killer at moments.

This book is dark, thrilling, and unsettling in all the right ways. Aldyn doesn’t just explore murder—she exposes the ugliest parts of humanity hiding in plain sight.

Suspense lovers, mark your calendars and run (don’t walk) to pick this one up when it hits shelves on June 10th.
⭐️⭐️⭐️⭐️⭐️ — 10/10, highly recommend!
