Book Title: Sister Butcher Sister

Author: KD Aldyn

What’s it about?
Sister Butcher Sister is a dark, emotionally intense novel about two sisters bound by trauma, survival, and a haunting past that never truly let them go. The story unfolds in a nonlinear way, gradually revealing what happened to them, what they’ve done, and how pain can shape—and sometimes destroy—the relationships we hold most dear.

Favorite Part:
My favorite part was how the story peeled back the layers of memory and pain so slowly but deliberately. There were moments when I had to pause and just sit with what I read—KD Aldyn has a way of making even the quietest scenes hit hard.

Thoughts on Characters:
The sisters were written with such depth and complexity. I didn’t always like them, but I understood them, and that’s powerful. Their pain felt real, their choices felt human, and their dynamic was both heartbreaking and compelling.

Would You Recommend It?
Yes, but with content warnings. This book is best for readers who can handle emotionally heavy themes like abuse, trauma, and mental health struggles. Fans of Sharp Objects or literary fiction that explores the darker corners of the human psyche will be drawn to this one.

Thank you to NetGalley and Poisoned Pen Press for providing me with the opportunity to review this book!

Sister, Butcher, Sister follows multiple perspectives and is a fast paced, gory and thrilling read. Kate, Aurora and Peggy are intriguing characters and I loved the additional POV of the mysterious ‘SHE’. Each sister is fighting their own demons, and as the past is brought back up, the line between vengeance and justice blurs disturbingly. This alone made it impossible to tear away from for me.

As brutal as it is, Sister, Butcher, Sister doesn’t hold your hand - it forces you to sit in the discomfort, and somehow, that’s what makes it feel so real. Reading it and watching the horror unfold feels like peeling back layer after layer of rot, hoping to find something beautiful deep beneath. The complexity of the narrative paired with the character relationships creates a haunting and powerful debut.

There are scenes that cut deep, especially around themes of sexual violence and childhood trauma - so please check trigger warnings before reading.

Thank you so much to Poisoned Pen Press and KD Aldyn for sending me this advanced copy to read and review. My opinions are my own.

Dark, twisty and creepy!

Three words I love when it comes to books!

Spending time in the head of creepy characters is the best way to use up time! And this book delivers.

The best time is the time when you're reading a character and muttering "oh shoot, I'm just like that too..."

I always read a synopsis before beginning a book because it helps me focus, but lately, I'm finding that too much of the plot is given away. I'm happy to say this wasn't the case with this book. What really worked for me was the alternating POVs, especially with 'anonymous' because I just couldn't figure out who it was.

I loved how unapologetically dark and disturbing the plot was, and with each new thing I learned about the sisters' past, the more upsetting the book became. I can't wait to see what this author comes out with next. Many thanks to NetGalley and Poisoned Pen Press for the early copy. This title is set to publish on June 10, 2025.

I really did struggle with this book. It seemed like something that I would love, but I was confused for most of the time. Jumping perspectives and 2 sex scenes in the first 10% really didn’t help either. I do love a serial killer book but this one just didn’t work for me at all.

Thanks to the publisher for the chance to read this, just not for me,

Thank you to NetGalley and the publisher for a gifted copy of this novel!

If you’re looking for a whodunnit thriller where one of your POVs is the criminal, look no further. This is a strong debut novel, punctuated by quick chapters and multiple POVs. Throughout the story, the author also weaves in the important concept of grief, and how it impacts everyone differently which I believed was well done. Although I was able to guess the whodunnit aspect before it was revealed, I think this was purely by chance. There were a couple of sections where I felt the pacing was slower than the rest of the book, but I realize that is unique to my personal reading experience. If you enjoy crime dramas and whodunnits, I think you would enjoy this novel!

This book definitely takes you on a horrific ride with three sisters who have a very strained relationship. They are all fighting demons, but one fights with real knives and a purpose.
It is very quick paced and flips back and forth between the sisters and the ‘butcher’, but it is easy to follow and not confusing. It will keep you guessing until the end, most likely!
It is indeed very graphic when it comes to the murders of men, so be warned.
There are also multiple things that deserve trigger warnings and the author has placed the warning in the front!

Thank you to Poisoned Pen Press and NetGalley for the digital ARC!

Three sisters. One killer. Which one could SHE be?
Sister, Butcher, Sister is a serial killer thriller told from each of the Rowling sister’s POV and the POV of our mystery killer.

The story revolves around Kate, Aurora, and Peggy who all live their separate lives until Kate purchases their late grandfather’s home dragging up unwelcoming memories. The sisters navigate their unstable relationships with each other while we try to find out who the killer is.

The serial killer, referred to as She, is targeting problematic men. She has an insatiable thirst for blood and killing these men brings her sexual gratification. Unlike typical female serial killers, her kills are delivered with plenty of gore.

This was a bit of a slow burn but once it picked up it just kept going. I enjoyed the plot, however I had a pretty good idea early on what sister was the killer and my guess was correct. Occasionally lost in the timelines they sometimes blurred a bit. Overall Sister, Butcher, Sister was a good read.


Thank you to NetGalley and Poisoned Pen Press for this ARC opportunity. This is an honest and voluntary review.

I wasn’t prepared for this! I knew there was a female serial killer in this book but the details of the killings were descriptive. I’m not squeamish at all but just don’t come across many with such detail. This book definitely isn’t for the lighthearted, I on the other hand enjoyed it. I have to admit that I wasn’t sure which sister was the butcher throughout most of the book. I do recommend this one to anyone that likes psychological thrillers.
Thank you Poisoned Pen and NetGalley for this eARC.

Really wanted to like this, but it just didn’t work for me.
The blurb hooked me, the cover looked great—but I felt lost for most of the book. The setup had so much potential: three sisters, one of them a killer. But the story never quite came together, and the twists didn’t hit the way I hoped. Just left me more confused than compelled.

I appreciate the opportunity to read this title, but unfortunately it didn’t quite capture my interest. While the premise was promising, I found it difficult to stay engaged. That said, I’m sure it will find its audience with readers who connect more strongly with the writing style or pacing.

I gave this book 3.25 but I want to preface my review with the fact that I prefer my thrillers twisty and action-driven; Sister, Butcher, Sister works more for readers who prefer their thrillers to be slow and unsettling.

It's a psychological thriller that builds its tension around a complex and chilling relationship between sisters, with a narrative that gives a creeping dread.
If you enjoy thrillers with layered characters, simmering tension, and family dynamics that unravel slowly rather than explosively, you may find more satisfaction here. It's not a twist-heavy, fast-paced thriller, it's more cerebral, emotional, and lingering.

There are plenty of trigger warnings for this book: sibling trauma, family secrets, and sexual assault/trauma involving children.

Great serial killer novel with multiple POVs and timelines. Three sisters living very different lives come back together after one buys their grandparentse old house. We get the POVs of each sister and also of the serial killer. One of the sisters is the culprit but which one? I honestly did not know until the end and I very much enjoyed guessing throughout the book. Highly recommend.

Dang!! This book was something else. I was not prepared. This book was dark and twisted where the author has multiple turns up their sleeves. I didn't know where I was going to end up chapter to chapter. I was constantly questioning people and wondering who done it.

Thanks to netgalley and publisher for copy.

Thank you, Netgalley, for this E-ARC. Three sisters, three suspects, and three traumatic childhoods. Who is SHE? You are left wondering which one has the motive and monstrous evil to commit these crimes. I was sucked into this book from page one, and with it being a little over 350 pages i finished it in two days! I enjoyed the depth each sister was given for character development. Check trigger warnings before delving into the master piece of trauma, sexuality, and brutality.

thanks to Netgalley for an ARC in exchange for a review

what a bummer! the premise of this book grabbed my attention immediately, as i’m a sucker for a good serial killer book, but unfortunately this one fell a little flat

the characters weren’t exactly likable and the timeline went all over the place. sometimes the murder scenes were a little too much, graphic depictions of violence serve their purpose but in this case it seems like they were done for shock value.

i do like how this book wove in how childhood trauma and PTSD causes ripple effects for people’s entire lives and the unspoken unresolved trauma is the worst of all.

✨despite the problems of this book, i’ll always support women killing men indiscriminately ✨

⭐️⭐️⭐️⭐️
Dark, twisty, and deeply unsettling—in the best way.

Sister, Butcher, Sister by KD Aldyn is a gripping psychological thriller that pulls you into a shadowy world of fractured identities and sibling secrets. The writing is vivid and cinematic, with an eerie tension that builds steadily until the final, jaw-dropping reveal.

I loved how the story explored the thin line between love and obsession, and how trauma can twist even the closest relationships. The atmosphere is haunting, the characters complex, and the pacing keeps you turning pages late into the night.

Perfect for fans of psychological horror with emotional depth and a sharp edge. I’ll definitely be watching for whatever KD Aldyn writes next.

Thank you to NetGalley and Poisoned Pen Press for the ARC and the opportunity to read and review this chilling novel

This captivating page-turner immediately draws the reader in from the very first page. The three sisters are intriguing characters, each grappling with their own unique struggles and challenges. The plot keeps you guessing, as you find yourself unable to put the book down. The author’s consistent writing style and effortless storytelling make this a truly enjoyable read. My only complaint, I wish they had a better title.

My review is voluntary and all comments and opinions are my own.

Well to start I finished this is one go- which I always consider complimentary. The author does a great job of peaking my curiosity. I just wish I hadn’t felt so starved for information most of the time. I would’ve liked less of our murder’s pov’s, and more building of tension in present time. Eventually those pov’s felt repetitive and less effective as a result. I was like ‘okay girl you’re really messed up. And you LOVE killing men. Now give me some information or plot I can use!’ It’s like with creature feature movies, sometimes the less you see the monster- the scarier it is in your mind.
Definitely got some karin slaughter vibes going here but I grew weary of some cliches and formulaic scenes. (Enough creepy folk songs!) As well as getting really fatphobic and haterish in the middle there, don’t really see how it was necessary, but our narrator wasn’t exactly the pinnacle of morality anyways. I was pleased with the ending, despite being rushed. Overall I liked this book well enough but it had potential to be better. *Please check tw’s in the beginning if you pick this one up.
