Three sisters - Kate, Aurora, and Peggy.
Kate seems the most successful one working as a lawyer and managed to purchase back her grandfather's house, which has lots of memories for them, good and bad.
Aurora, married with two children, finds her tranquillity through her harp instrument.
Peggy, the broken one, since teenagers she became alcoholic, however she's in the way of recovery.

I love the narrative style by each sisters and especially love those chapters by the anonymous murderer as it really tickles my curiosity of which sisters is the Butcher.
It's gory, it's haunting, it's dark. I also love how the author kept dropping red herring to try pointing to each sister as the butcher, but there's only one !
This is a good read. It's totally hard to stop reading as I could only wish that I could read this in one sitting!

3.5 ⭐️

Dark, unsettling, and strangely poetic — this book definitely left a mark. The writing is sharp and immersive, with a haunting tone that lingers long after finishing. I loved the themes of sisterhood and survival, and the eerie, almost dreamlike atmosphere.

That said, a few parts felt disjointed and hard to follow, which pulled me out of the story at times. Still, it’s a bold and memorable read if you’re into gritty, genre-blurring fiction with a psychological edge.

I liked the concept of the three sisters who appear perfectly normal, but one of them has a mystery POV, and SHE is a killer. The POV shifts between the three sisters, which I found fun when trying to figure out which sister is the warped one, although they all have skeletons in their closets.

This book had such a strong premise—dark, graphic, and full of tension—but ultimately left me feeling a bit underwhelmed. Holding off on revealing which sister is the butcher until the final chapter only makes sense if there’s a sequel on the way. Otherwise, it felt like the literary equivalent of edging.

The writing itself is vivid and unsettling in a way that works for the story—it leans fully into its horror elements, and the gore is more graphic than I anticipated (not a bad thing, just worth noting for sensitive readers). With sisterhood and forgiveness at the heart of the story, I was disappointed that we didn’t get to see a more emotional resolution—especially a moment of connection or reckoning between the sisters after the reveal.

Overall, it was an enjoyable read, but the ending felt rushed. Worth picking up if you like your thrillers gritty and don't mind some ambiguity.

⭐⭐⭐⭐⭐
Utterly Unnerving—and Brilliant

"Sister Butcher Sister" sinks its teeth in from the opening frame and never lets go. The story is disturbing in all the right ways, threading a razor-fine line between horror and psychological drama. But let’s talk about the real shocker: the children. Some of them are absolutely disturbing—and I mean that as a compliment. Their performances are chillingly precise, unsettling enough to haunt your dreams.

This isn't your typical horror fare. It's smart, bold, and unafraid to get under your skin. If you're into intense sibling dynamics, slow-burning dread, and unnerving little smiles from children who know too much... you’ll love it.

Unforgettable.

Thank you Netgalley & Poisoned Pen Press for the eARC of Sister Butcher Sister by KD Aldyn in exchange for my honest opinions.

This book is absolutely unhinged in the best way. It follows three sisters, each unraveling their own buried traumas, secrets, and fractures in reality. But here’s the kicker: one of them isn’t just haunted by the past… she’s actively making new ghosts. 👀

Told in three twisted, deeply unreliable POVs, you’re constantly questioning what’s real, what’s imagined, and who’s holding the knife.. literally. It’s dark, tense, and layered with so many turns it’ll leave your head spinning and your trust issues flaring. Just when you think you know who the real danger is, the story sharpens into something even more disturbing.

This isn’t your average sisterhood drama! It’s messy, mind-bending, and dripping with dread. Highly recommend for fans of psychological thrillers that aren’t afraid to get bloody weird.

Gripping story! I could not put this down and was immediately drawn into all the characters. I truly was trying to guess which sister was the "she" throughout and I can say that I had my guesses but was still surprised by how this all played out. Well done and I cannot wait to read more from this author. Will definitely add this one to my own home library! Plus, this cover is amazing!!

Thank you to NetGalley and Poisoned Pen Press for the eARC!

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.
