The premise of this story really grabbed me and got me out of a reading slump. How far would you go to find your sister's killer?

Cyra gets a tip that there's a group of serial killers meeting in NYC as a support group and she suspects that one may have murdered her sister. She's tired of waiting on the police so she decides to infiltrate the group and pose as another serial killer.

The multiple stories of the characters throughout Cyra's investigation into the group was fascinating. Especially when members of the support group started dying.

I couldn't put this book down. It was more than a who-dun-it. It was who and how and why? All wrapped up in a whirlwind of chaos and intrigue.

I highly recommend this for fans of mysteries and thrillers. Thank you to NetGalley and the publisher for providing an advance copy in exchange for an honest review.

Thank you to NetGalley for providing advanced copies of this book. It’s a different kind of thriller than what I’m used to—unique, dark, and very intriguing.

The story follows Cyra, who infiltrates a support group for serial killers in search of her sister's murderer, driven by the need for revenge. While the book primarily focuses on Cyra, a few chapters are told from the perspectives of the killers, which was a creative way to showcase different mindsets.

For me, the book was a bit more gruesome than expected—extremely dark and graphic in its depiction of violence.

Cyra is a complex character. She’s deeply broken after her sister's death and consumed by revenge. She’s not exactly likable, but her story compels you to keep reading as you unravel the mystery of her sister’s killer.

I’d recommend this to readers who enjoy dark thrillers. It’s intriguing and offers something different, though it was personally difficult for me to get through due to its brutality. The author did a great job delving into the unsettling minds of the killers, but the intensity may be a bit much for some readers.

So this book was something. The story in itself was nice, but Cyra's head is a bore to be. She is so 2 dimensional that from the 1st chapter i knew she'd become a killer. The whole thing with Izzie was well done, and i loved the insights into the heads of the other killers, but i feel like they were dispatched too quickly. The whole thing with Cuckoo hating blue was an unecessary detail, Whipworm was essencially a doll after the first chapter, Python was a bulldog or a pitbull - threatning only in theory, Lamprey was very interesting but his role was done so quickly, Mockingbird was also useless as he did literally nothing.
I didnt love the book and i don't think i'd recomend it.

This book turns out to be a huge mess and outright stupid at several places. I found it extremely hard to even cross the finish line. Should've DNFed.

3.5
This book definitely caught my attention with its title. Always morbidly fascinated with serial killers I was curious to see where this book would go. Here in NYC there is a serial killer support group that is well protected but allows a way for the serial killers to meet with like minded fellows.

I couldn't quite catch what the author was trying to do regarding the feel of this book. It wasn't quite morbid, but kind of was. It was kind of light, but also not. I wasn't sure how to read the room in this book. It left me unsettled by the end.

I thought this was a clever plot and enjoyed the storyline, but had to dismiss some belief at times. I saw a few holes that by the end I was questioning some things.

Overall it was a fun ride!

Thank you to NetGalley and Crooked Lane Books for the gifted e-copy of this book.

This book has such an interesting title / cover / plot that I was instantly intrigued! I was expecting a thrilling thriller with lots of intrigue, complex characters, and murder. Instead I got a flat book with very little substance.

I unfortunately lost interest in this book pretty quickly. The FMC isn’t particularly interesting and she’s able to change herself too easily and quickly to be realistic. She’s also able to fool a group of serial killers by putting on a wig and practicing facial expressions in the mirror for an hour?

Once we meet the other serial killers at the support group, I was expecting this book to really pick up, but I had a hard time keeping everyone straight because they sounded the same. The author did try and make each one unique and give them a characteristic or two to stand out, but it wasn’t enough for me.

Ultimately after the first time I put this book down, I never wanted to pick it back up again. I forced myself to get through about 30% and then finally gave up.


Thanks to NetGalley, the author, and publisher for sending me a free copy in exchange for a review!

I don't know why there are so many people angry about this book. I found it DELIGHTFUL.

It was so fun, and I loved seeing Cyra's character spiral from pretending to have the moral high ground to being perfectly morally black. I loved the interludes about each of the killers and the exploration of different motives for killing while still not forgiving these people for being killers (it was especially not forgiving of sexism, which was lovely). The gore was just the right amount, and the character development for Lamprey was especially fun.

Maybe it's because I don't read a lot of these types of books. If I did, maybe I would be a bit more discerning. All I know is that I could not put this one down and I had a great time reading.

Cyra Griffin's journey into a support group for serial killers in search of her sister's killer is an intense dive into darkness. Cyra's descent into this world is fraught with danger and moral dilemmas. The plot twists and gripping narrative make it a must-read. You'll be questioning just how many unseen monsters lurk among us. This debut novel is a dark and witty and unlike anything I have ever read before.

Really enjoyed this one, it would be a great counterpart to the Final Girls Support Group! The one drawback was that I guessed the big twist fairly early on. Still, this was a real page turner, with a nice noir feel, Recommended.

I can't imagine having the guts to sit in a room of known, self-professed serial killers. I don't think I'd be as calm as Cyra. I know she wants to find out who killed her sister, but there has to be limits, doesn't there? The idea of a serial killer support group is definitely interesting and they are certainly an interesting set of characters. Overall, enjoyable to read!

Great premise and plot concept. Characters were a little cliche. Would have loved to see more of the feminist, queer idea built out.

‘After her sister is murdered, a woman infiltrates a support group for serial killers in this biting queer feminist debut thriller, perfect for fans of The Final Girl Support Group and My Sister, the Serial Killer.’

Serial Killer Support Group - such an alluring and unique concept. Problem for me was the lack of depth & development in the characters & something about the delivery left me wanting.

That said, I am always grateful for the opportunity. So big thanks to NetGalley and Crooked Lane Books for this arc in exchange for review!

This book is not a mind-bending, seat-gripping thriller. It IS a silly, goofy read. I thought it was good and fine, and I enjoyed my time reading it, but I don't think it's a story that will sit with me for a long time. I enjoyed the complicated relationships between all of the characters (or perhaps just that Cyra was a complicated person because, well, she was weird). I also enjoyed the different kinds of killers described in the support group - as a true crime junkie myself, it felt fairly representative of the common stereotypical serial killers.

Overall, I did not love this, but I did like it, and that's enough for me.

SPOILERS!!!!

This book had a very unique and interesting premise. In my opinion, in order to enjoy this book, you need to go into it expecting it to not make much sense if you think about it for more than a few seconds. Once you get over the initial disbelief in the concept of a serial killer support group that meets weekly in person, it gets good.

I liked the author’s description of the main characters emotions in the first quarter. It felt like a good depiction of numbness due to grief and loss. However I felt as though it was a huge jump to the actions she was taking. But, as the story went further on you began to realize that the grief only made the fmc’s numbness worse. She already had something dark inside her that she had acted upon on multiple occasions but the death of her sister gave her an excuse to spiral. The way we got to go along with her on this journey of becoming a serial killer was really interesting.

The ending was not at all what I expected. A good twist when it came to who killed her sister, but I found myself hung up on the whole Lamprey situation. I don’t find it believable that she managed to kill him when he came there fully prepared and she was caught off guard. With the way he was described through the entire book, I don’t find it believable that she out fought him. Other than that, I really enjoyed this book and flew through it!

This was kind of creepy. A little more scary than the usual thrillers I pick up but I enjoyed the twists added in. If you like true crime and psychological thrillers, this should be on your list!
When our main character's sister is killed, the cops don't have any leads, but she knows they aren't telling her everything. When a friend in the records room tells her there were signs her sister was killed by a serial killer, she can't believe it. When she finds out there might be an underground serial killer support group in the city, she vows to infiltrate them and find her sister's killer.
It gets creepy when we start learning more about each serial killer. This is a mystery but I would say it means horror/thriller. Maybe I'm a wimp? Lol.
Definitely a fun read that kept me wondering what was going to happen next.

Serial Killer Support Group follows Cyra, who recently lost her younger sister to a presumed serial killer, as she infiltrates a group of them in order to find her sister’s killer.

The premise is a little cheesy—however I really enjoyed the execution. It didn’t take itself so seriously, but wasn’t a complete joke either. I have a degree in forensic science with a heavy interest in psychology, and some of the content did feel a bit ‘Intro to Forensic Psychology’. It could just be how familiar I am with those topics making them seem tedious and surface level, though, and the book itself was very enjoyable anyway. I don’t read for realism, but when it’s my area of expertise I do find myself aghast sometimes.

I enjoyed the twists in this thriller more than I usually do, specifically towards the back half. At times it felt like it was leaning one way, but I’m glad it didn’t end up there. The Lamprey character is a big wildcard in that respect.

There are interspersed POV chapters from each of the killers in the support group, and I wasn’t quite sure how necessary they were. They’re shorter than the usual chapters, and entertaining enough that I don’t think they break the flow, but they read more as writing exercises than necessary information. They do build up to the epilogue though, and that made it worth it in my opinion.

I was very pleasantly surprised by Cyra’s character arc in this novel, especially where she ends the book compared to how she starts it. I wasn’t sure I’d like her as a narrator at first, but her internal struggles and later choices made me interested in where she’d end up.

Overall I enjoyed this one a lot! I liked the direction the plot went in and the characters felt like they fit the world nicely. I think this will appeal to thriller fans and anyone with a passing interest in psychology!

Rounding up from 3.5 stars for this one. Serial Killer Support Group was an action packed book, there was constantly something happening which kept my attention. It also made it pretty far fetched- but if you go into expecting that it is enjoyable. I enjoyed the twists! Thanks to Net Galley, the author, and Crooked Lane Books for the ARC.

The Serial Killer Support Group was just an ok read for me. I absolutely loved the premise, but it fell a bit flat for me in the execution. I also figure out the twist/killer very early on and that sort of detracted from my enjoyment of the book. That being said, if the author wrote another book, I would still read it.

I really would have liked to get more in the minds of the group members, I feel like they are introduced but we didn't really get to explore much into their killings etc. We had snips of their lives.

The main chatacter was annoying, and I felt like the story wasn't developed well enough to keep my attention. I struggled wanting to pick this up and read it.

Overall it was just not for me.

When I read the synopsis I said: I need to read this, for better or worse.

And the truth is that it turned out quite well. I mean... it was a super addictive read that at times I really wanted to miss work to be able to continue reading and at other times I wondered how certain things were happening...

Serial Killer Support Group presents us with the most imperfect characters of all I have read so far and one cannot empathize with any of them at all. And I think it's something the author was looking for, they are all gray or malevolent characters (even the most 'innocent' ones).

It was interesting about the Support Group for serial killers (although I was already able to read some of this thanks to Katzy) and how our protagonist manages to enter that dark world (although she was not very far away before).

Anyway, I think it was an interesting read... with some pretty crazy aspects but that also left me wanting more with each chapter I read.
