Let me just say this right now, this book is dark. I think this is the perfect book for fans of dark crime.

Three sisters, one killer. Peggy, Aurora and Kate. Then we get a POV from SHE. Your job is to find out who she is.

The past traumas are a huge factor here. There’s trigger warnings galore. You’ve been warned.

Perfect for fans
- You
- Dexter
- Serial Killers

Thanks so much to Poisoned Pen Press for the gifted copy.

Thank you poisoned pen press for an early copy of this book in exchange for my honest feedback!

Pub date: June 3 2025

Throughout this story we get a POV from each sister and a 4th POV from the one who is a killer and we’re trying to figure out which of them it is.

Right away I had my theory and I never wavered in my belief of who it was. I didn’t have all the answers but I knew who it was the whole time.

Regardless of me knowing exactly who it was, I still found this story really interesting. The dynamics of the sisters getting over deep traumas of the past, paired with the everyday obstacles and changes in their lives was compelling. There were tidbits of background thrown in throughout that gave could lead a reader to believe a depraved serial killer lived within any of them.

I found the overall reveal, reasoning, and resolution to be satisfying and it left me feeling like I wanted to hug my sister.

Kate, Aurora, and Peggy are just your average sisters. They don’t always get along—in fact Aurora may never forgive Peggy for what she did. Oh, also, one of them may be a serial killer…

When Kate purchases her grandfather’s old home that the girls grew up in, she is elated but Aurora and Peggy are skeptical. The house has its pleasant memories, certainly, but its halls are also filled with dark memories that threaten to take hold of the sisters’ present lives. When a string of murders occurs, suspicion turns toward the Rowling sisters causing old, buried secrets to rise to the surface and forcing the sisters to face their past.

In Sister, Butcher, Sister readers receive a viewpoint from the killer—simply narrated as “she”—which was interesting but some of the scenes could be quite gruesome. Aside from the murders and all, there is something clearly worrisome going on with the sisters and the tantalizing prose forced me to keep reading in the beginning but I started to lose steam around the 40% mark.

The passage of time is difficult to keep track of in this book; a clearer timeline could have led to less confusion for the reader. In addition, there were parts where it seemed like the author was struggling to get to what they wanted to say leading to an uneven reading experience and a lack of flow. Wordy in places; this could have easily been trimmed down to a tighter, more concise story.

For me, just an ok story that needed a lot more work. The author seems like a good writer but I don’t think that their full potential is on display here so it will be interesting to see what they do moving forward.

First and foremost, a large thank you to NetGalley, K.D. Aldyn, and Poisoned Pen Press for providing me with a copy of this publication, which allows me to provide you with an unbiased review.

Always excited to get my hands on the novel of an author I have yet to discover, I was delighted to get my hands on this piece by K.D. Aldyn. A dark and captivating story about three sisters and one’s sadistic plan is sure to pull the reader into the middle of this piece, while leaving them questioning everything until the final page turn. K.D. Aldyn surely makes her mark with this piece, forcing the reader to decide how they feel about it all.

The Rowling sisters have always been quite personable and well respected in their community. Their family lives are the talk of those around them, but the sisters also have secrets locked away. Some begin to emerge when the eldest, Kate, returns to take ownership of their grandfather’s home. The buried secrets poke out and things turn sinister once again.

Kate tries to make sense of the visions she has from her past. Aurora, the mother of two, has only shards of recollections regarding what the sisters did in their youth. What about Peggy, a recovering addict with skeletons of her own, who can hardly piece together her day to day routine? Nothing is clear as things slink towards the sinister.

Amongst them is a killer, whose brutal acts leave men in a bloody pulp and begging for their lives. One of the Rowling women has taken to luring men to her and killing them in the most horrible fashions. Who it might be is anyone’s guess, but that darker side must be held in check or everything else could cause ruin. K.D. Aldyn surely makes her mark and serves up a chilling piece.

I usually enjoy a good piece of crime thriller fiction, especially if there is an element of horror involved. K.D. Aldyn creates a piece that pulls on all key aspects and presents them in an impactful novel. The narrative moves along and gains momentum from the outset. While I could not connect as well as I might have liked, some will surely enjoy the story’s progression. Characters were also well placed and, for some, easily relatable. I felt a disconnect and lack of empathy for the Rowling women, but can see how many might enjoy them. The plot inched forward and proved chilling for some, which I hope works well for many readers. For me, it was a decent effort that lacked the ability grab me by the neck and shake things about!

Kudos, Madam Aldyn, for a valiant effort that I hope others find even more alluring than I did.

This was a page turner I desperately wanted to know who the killer was. Three sisters , one killer , who is She? This book is told through multiple POV’s including that of the very disturbed gruesome killer. We follow along all three sisters lives currently and things they had experienced as children good and horrible.

Thank you to NetGalley and Poisoned Pen Press for a complimentary early release copy of Sister, Butcher, Sister by KD Aldyn.

I found Sister, Butcher, Sister to be a decent/okay kind of read. The characters were interesting to follow and I’m happy that we got perspectives from multiple people during the story as it added an extra element of “who am I to trust” or “what happened”. I liked the sisters and I found their life’s to be interesting, I even liked a few of the love interest for the sisters. The plot and characters kept me invested but I wish a few things had played out differently.

This thriller is certainly one of the darkest ones that I have read but I didn’t really like the perspective of “She”. The timeline of the story also tended to jump around mid chapter sometimes making things confusing to follow. While I didn’t guess the ending I’m a little disappointed by how things had played out in the end, I wish we would have gotten just a little bit more between the sisters. If you have any triggers I highly suggest looking up trigger warnings before reading, there are lots of heavy subjects and gore included in this book.

Sister, Butcher, Sister by KD Aldyn is a psychological thriller about three sisters who each see their past differently.

First, let me thank NetGalley, the publisher Poisoned Pen Press, and the author, for providing me with a copy of this book in exchange for an honest review. All opinions are my own.


A warning.  There is a lot of graphic violence and sexual scenes in this book.  Neither of these bothered me, but I am sure others may take offence.  A few problems....Sometimes the pacing was a little off. There also seemed to be a bit of repetition, and sometimes the author got a little wordy.    That being said, she could have expanded a little on the ending.  

Okay, after all that, I really enjoyed this book.  I loved the intricate relationships between the three sisters, and loved how very different their memories of the past were.  I think that really rang true.  People can see the same event very differently.

The story is told from multiple points of view, including that of the killer.  This worked really well, and although I was proven right in my "guess" as to the perpetrator, it really could have been anyone.  It was truly a mystery.

I was fully engaged throughout.  It was a very dark, yet very entertaining read with complex characters, and a rather creepy feel about it.  I loved it.

Anyway, until next time....

🔪Sister, Butcher Sister by KD Aldyn is a dark, perplexing and unsettling debut that ensnared me from the very beginning and never quite released me from its grip. With an ideal mix of intrigue, unease, family history and trauma this was disturbing but top notch read. I’m so glad I shared this one with the best in the biz @nadsylovesbooks

🔪KD Aldyn’s novel follows three siblings who must confront a past they all thought was long buried. As the story unspools, old trauma, family secrets and fractured kin relationships rise to the surface when a series of horrific murders of male only victims rip through their town. As suspicion is cast on the three sisters, the truth inches closer and fingers are pointed at each of the Rowling siblings. So just who is responsible for these heinous crimes?

🔪Rounding off a highly memorable year of reading and increased buddy reads, thanks to my partner in book crime @nadsylovesbooks, KD Aldyn’s book was the last of our buddy reads of 2025. I’m so glad this was a buddy read, it honestly allowed plenty of room for us to discuss the themes, situations, form theories and cast potential blame on each suspect. Sister Butcher Sister is quite a dark novel with some disturbing scenarios presented so I was glad to have a supportive buddy reader by my side as I worked my way through this consuming read.

🔪I opted to listen to KD Akdyn’s novel on audiobook and I must give my appreciation to the narrator, she truly made this such a addictive listen. Aldyn is a new face to me and I know after I had a read only a few chapters of this novel, I resolved to read anything new she releases. Bonus too that Aldyn is an Australian author. This one gave me some fantastic Dexter style vibes, with a feminist slant.

Aldyn exposes us to themes such as Family bonds, shared sibling history, hidden trauma, memory, identity, perception, the cost of silence, repression, the bystander effect, duality, vengeance, violence, personal choice, rage, resentment, protection, abuse, control, reputation, disassociation, self punishment, silence and mental illness. These are a heavy topics, by Aldyn incorporate these into her novel with intention and thought. The result is a narrative that cannot be ignored, it is utterly gripping.

For me, the best part was trying to solve the central riddle of which sister was the perpetrator of the crimes occurring against men in a coastal town. I know I switched and flipped a few times over which sibling was ultimately responsible, until I eventually settled on the correct perpetrator towards the latter end of the novel. My emotions twisted and altered from empathy, sadness, sorrow, anger, shock, understanding, sickness and hope. KD Aldyn makes us feel a great deal of sympathy for the Rowlings despite the circumstances around the murders, she also lets us see right into the very human side of the impact of a long term violence and exploitation, which reaches into the current family lives of the women directly involved. I really appreciated the inserted extra viewpoint of the officer charged with hunting down the killer. It was a thrill race towards the end.

Sister Butcher Sister was a book that completely consumed me. I have absolutely no hesitation in recommending this one, it’s harrowing and intense but carries so much emotional weight I suspect it will stay with me for time to come.
⭐️⭐️⭐️⭐️⭐️5 stars!

Told from the POV of three sisters- Kate, Aurora and Peggy. One of which is a killer, told from the POV of SHE.

Can you figure out which of the sisters is a serial killer?

There is a lot of trauma to unpack with this one and if you can get past the slow burn of it, it’s a well written psychological thriller about the secrets siblings hold. Check the context warning ahead of time if you have any triggers!

The story unravels the lives of each sister, giving you a glimpse into their memories growing up. The SHE chapters are dark and you will know you are in a SHE chapter pretty quickly!

I did have to pay extra attention to which chapter was focused on which sister. The chapter typically started with a name to give you the heads up.

Thank you to author, KD Aldyn, Publisher Poisoned Pen Press and NetGalley for the opportunity to read this book. I am leaving my review voluntarily.

”Don’t you think women are capable of evil?”


Sister, Butcher Sister is a twisty family drama with a sinister hidden edge. The three Rowling sisters each have their own baggage, and as secrets unravel and suspicions rise, you can’t help but wonder who to trust - or fear.

”That house; Grandpa’s house. There were things rattling around there that didn’t deserve air”


The eerie setting and creepy vibes kept me hooked until the last page, but the pacing felt a bit stuck in a loop at times, like it was circling the same scenes over and over again.
The ending was not as satisfying as I wanted it to be and I do wish the author explored the mysteries revealed a little bit more. With that being said, the story still delivers great dollops of mystery and it was extremely satisfying to see the pieces fall into place and the killer’s motives revealed.

A thank you to the author and NetGalley for providing me a copy of the book in exchange for an unbiased and honest review.

Ehhhhhhhhhh lackluster.
I went into this book with high hopes, and unfortunately my hopes were too high. It’s not a bad book by any means but I wanted so much more from it. The three main characters were far too similar and I didn’t care/connect with any of them.
Great concept but poorly executed in my opinion.

Female serial kill in the family. Three sister but you don’t know which of the unstable women it is.
This story had me locked in from the beginning. You get all three sisters POV’s and the killer’s too. There is a lot of family drama dragged up and repressed memories. I found this story to be very entertaining and fast paced. Such a fantastic debut author. I can’t wait to read more of their books.
This is a darker story with many trigger warnings.

⚠️ Trigger warning for graphic violence, sexual assault, and other trauma-related content. ⚠️

Three sisters. One killer. And way too many secrets.

When Kate moves into her grandfather’s old house, it brings her closer to her sisters—and dangerously close to buried memories. As a serial killer targets men in brutal, gory ways, we get chilling POVs from all three sisters… and the killer.

This book surprised me in all the best (and bloodiest) ways. I wasn’t expecting the level of gore, but I’m not complaining—it added to the intensity and psychological unease that builds throughout. While the pacing started off a little slow, it quickly hooked me. The tension builds beautifully, and the psychological twists had me constantly second-guessing everything. I suspected each sister at some point.

This is a dark, bloody, and deeply psychological read that I won’t be forgetting anytime soon.

Thank you to the author K.D. Aldyn, Poisoned Pen Press, and NetGalley for the ARC.

I gotta say, as a crime scene investigator, I feel embarrassed that I guessed the wrong suspect in this book 🙄 otherwise, I did enjoy this book and the pace with which it could be read. I enjoyed how the author gave little hints that made you think the killer could be any one of the three sisters, but then would hint at something else and make you doubt yourself all over again. I have three stars because I felt the ending, after the killer was revealed, was anticlimactic. The book just ended. I would have enjoyed a little more explanation into the killers psyche, but overall a very solid read!

Three sisters. One of them is a killer. But which one?

This story unfolds with an eerie slow burn that is tension filled. The chapters shift perspectives in a way that keeps you guessing. While I had my suspensions, the ending reveal still hit hard.
If you like your thrillers dark, brutal and family trauma, this one needs to be on your radar!

A good read.
Three sisters. One killer. Which one is SHE? With this chilling tagline, KD plunges readers into a gripping psychological thriller where familial bonds, buried secrets, and unrelenting suspense collide.
Likes :-
1 Unique Narrative Style: The alternating perspectives between the three sisters—Kate, Aurora, and Peggy—and the enigmatic SHE create an addictive, layered narrative. The ambiguity of SHE’s identity keeps readers on edge, constantly re-evaluating their suspicions.
2 Complex Characters:
a) Kate: The reluctant returnee grappling with unsettling visions tied to a fractured past. Her storyline adds a haunting, almost supernatural layer to the mystery.
b) Aurora: The seemingly perfect sister whose cracks reveal suppressed frustrations and simmering rage.
c) Peggy: The youngest sibling, whose battle with addiction provides both vulnerability and strength, making her arc deeply emotional.
Dislikes:-
1 Pacing: The first half of the book is slower, focusing heavily on character development and backstory. While this pays off in the latter half, some readers might find the buildup too drawn out.
Overall:- This is a must-read for fans of psychological thrillers and family dramas with a sinister edge. With its haunting prose and shocking twists, Sister Butcher Sister is sure to leave readers breathless and questioning how well they really know those closest to them.

i read the majority of this on a flight and it was honestly the perfect trip/vacation read. i really enjoyed the multiple POVs of the three sisters and all their individual storylines. i kept going back and forth on which sister was the killer so i was intrigued enough to keep reading to find out. it was a fast paced thriller/suspense that kept me guessing until the big reveal.

This is unfortunately one of those novels that has an alluring premise, but doesn't deliver. I didn't like any of the characters, the plot was extremely convoluted, and while a lot of murders occurred, not a lot actually happened in the book.

The ending was incredibly rushed with no natural progression and I had guessed the killer at around a third of the way through so that wasn't even a great twist.

This is a very mediocre novel that I can't recommend.

“She imagined herself literally f*cking them to death, these poor excuses for human beings, and the excitement of such thoughts would lead to the fantasy of sucking their blood. She loved the metallic taste of it, its viscous qualities.”

“She would find the bastard and show him a thing or two. She’d carve her initials into his body, swim in his blood. Drink it. She’d change his views on Women Who Kill.”


I went into this one blind and that was a great decision. Some jaw dropping quotes and the cover is so pretty. The girls’ upbringing maybe became long winded through the middle but overall I had a good ass time with this one. The “SHE” POV chapters were so unhinged and my favourite. Solid, dark thriller debut. Recommend for some stabby fem rage vibes!

Audiobook; it was a quick listen, listened to it in one day, a two because I found it easy to get distracted from it and didn’t have a strong urge to rewind, there were several parts that were way to graphic and I felt like I need more at the end for all the build up the book went through I felt like it just told you the killer and then it was over

Thank you Poisoned Pen Press & KD Aldyn for this read!

This book is dark and graphic- just how I like my thrillers. Told through 3 POVs, one sister holds a secret inside and through the book us readers go back and fourth figuring out who is the guilty one.

The plot was really good and I was really invested in finding out the truth. It was a little on the slow side and I did find sometimes the voices of each 3 sisters started to fade into eachother.
