Enjoyable read! By day, Cordelia is a pharmaceutical rep. She's been known to fudge a little on her reports with help from a friendly doctor. This sets the stage for her evening hours occupation as a serial killer. She knows how to get the job done without betraying her identity, methods and means. She's not always likeable...it's hard to like someone who leaves their victims iced down in the bathtub a wee bit too long and then leaves body parts in the kitchen refrigerator freezer. She's a good gal, but she feels completely fine about offing men who just don't do her or her friends right. Not as funny as I thought it would be. But, it's not intended to be funny. You will love it! My thanks to Emma C. Wells (are you related to Orson Wells??), Poisoned Pen Press and Net Galley for the ARC.

A gripping and entertaining read. A serial killer that is likeable? Yes please.
Many thanks to Poisoned Pen Press and to Netgalley for providing me with a galley in exchange for my honest opinion.

Vigilante men murderer?!?! Yes! Sign me up right now. This is right up my alley and I thoroughly enjoyed the ride. Cordelia was just.... Chefs Kiss! I absolutely loved her and her storyline. I wanted more, need more. Highly recommend.

I thought this book was going to be a fun and thrilling read but it was not for me. It dragged and while the beginning was fun, it quickly started to drag for me. While this book wasn’t for me, I would like to read a different book from this author.

Thank you so much to netgalley and the publisher for the arc of this one in exchange for an honest review!

This book follows a woman who kills bad guys. She is like the female Dexter. When her bestie gets a new suspicious boyfriend, Cordelia has to determine if he is actually bad or not.

Unfortunately, this book didn’t work for me. I feel like it totally just copied Dexter and didn’t offer much else for me.

It was also very repetitive for me. Cordelia just kept thinking and saying the same things. She was also just annoying as a character.

I hope others love this one but it wasn’t for me.

It immediately draws you in with its morally complex protagonist. Cordelia Black, by all accounts, is a woman who knows exactly what she wants—and how to get it. Her unique form of justice, rooted in her belief that she’s simply the vessel for karma, sets her apart from your typical antihero. Her daily life as a pharma rep contrasts starkly with her secret life of vigilante justice, making her a fascinating character who treads that line between righteousness and madness.

Her motivation—eradicating “bad men” who think they’re untouchable—feels both cathartic and chilling. The fact that she’s so calm about her actions, even as the news calls her a serial killer, really speaks to her deluded sense of control. The tension heightens when her world begins to unravel, especially with the threat of her best friend getting involved with someone Cordelia suspects might be one of the “bad men” she’s sworn to protect her family from. It’s the kind of setup that makes you question where the line between justice and obsession really lies.

What works well in this story is how Cordelia’s moral compass is tested—not just by external forces but by the very people she loves and the life she’s built. The stakes are personal, making her decisions that much more compelling to read. As the pressure mounts, you can’t help but wonder how far she’ll go to protect the delicate balance she’s created.

A great debut thriller/mystery/horror that kept me on the edge of my seat from the first page...what a book!!!

Dark comedy thriller with a posh southern belle female killer protecting her found family. Dragged a bit for me to gain another star but an entertaining read. Thanks to NetGalley and Poison Pen Press for an advanced copy for a honest review.

This review is hard to write because there were some parts of this book that I found really compelling (4 stars!), but others that I really didn’t care for (2 stars). The writing was pretty simple and straightforward, which makes it totally bingable. But the main character, Cordelia? She. Is. Unhinged. I think her vigilantism was meant to make her understandable, if not straight up likable, but girlfriend’s a psychopath. I also found the depictions of violence pushed this book into the horror genre (which I enjoy from time to time, but wasn’t looking for when I picked this up). Ultimately, I probably wouldn’t have finished this if I hadn’t gotten it through netgalley– not because it was bad, but because it wasn’t just the book for me.

If you like the Finley Donovan books (also wasn’t for me) and don’t mind more violence/gore, you’d probably like This Girl’s A Killer.

I thought this book was pretty good. I enjoyed the vigilante character of Cordelia. It took me a few times to get into this but I ended up enjoying it

This was a fun book for a thriller! I love a good vigilante story and Cordelia black was such a fun character to follow along with! The twist at the end definitely kept me on my toes!!

This is a fun vigilante story – bloody and gory but hey, they deserved it, just ask Cordelia!

This is one of those times when I did, indeed, root for the morally grey character – Cordelia is a badass with a heart of gold. Suspenseful and messy, just how I like my female rage novels!

Thank you Poisoned Pen Press for this gifted DRC!

"This Girl’s a Killer" had a promising start, and I was ready for a wild, morally complex ride. But instead of a morally gray antihero, we got a full-blown psychopath—no shades of gray, just straight-up unhinged. The main character's obsession with her best friend wasn’t just intense; it was downright toxic. She framed her actions as "protection" and justified her bloodthirsty ways as making the world a better place. But the book gave me almost no real insight into why she was like this, which made it hard to feel anything for her beyond frustration.

I found myself skimming through large chunks because it felt like listening to someone endlessly justify their bad behavior—convincing themselves that their trauma gave them a free pass to be a ruthless killer. And yet, I kept reading. Why? Because I’m a sucker for thrillers and mysteries. No matter how much I wanted to DNF, my curiosity won out—I had to see how it all wrapped up. Spoiler: it wasn’t worth it.

There was no lesson, no real theme, no consequences—just chaos, messes she made, and a finale where she slithered out of it all, lies and all, with zero accountability. It felt less like a thriller and more like watching someone dodge karma in real time. Disappointing.

Thank you to NetGallery for the opportunity to read this novel. I have really loved that this is new type of genre/play on looking at what we would normally see as the antagonist as the protagonist of the story. I loved the wit, banter, and thrill of this debut novel. I am excited to see what Wells publishes next.

Very interesting read. Was fun, the characters were well written. Very much enjoyed reading this one

This was such a fun book with a Dexter-like female character. Would love for it to be a tv series or movie!

"This Girl's a Killer" by Emma C. Wells is one rollercoaster of a thriller! If you're up for a wild ride and don't mind suspending disbelief a bit, this book delivers. It's the kind of read that grabs you from the start and keeps you guessing till the very end. The plot twists are like sharp turns on a dark highway—you never see them coming! Wells really knows how to keep the suspense going. It's not just about the whodunit but also the whydunit that keeps you hooked. Overall, if you're in the mood for a gripping page-turner that doesn't take itself too seriously, this one's a winner.

Hmmmm... I seem to be in the minority on this one, but this didn't work overly well for me. It was a quick read, which I appreciated, but I feel like the author was going for a female Dexter. However, I didn't believe it. Cordelia is supposed to be this meticulous serial killer who has gotten away with countless murders easily. But in this story, she is not careful or detail-oriented or even very smart. She makes bad decision after bad decision and mistake after mistake. So even though the author tells us she's good, that isn't what is shown. I didn't understand the whole "smoke in their eyes" thing either. That seems a bit... contrived and unexplained fully. Plus, with the premise, I honestly thought we'd get more about her process of finding, luring, and killing her victims. There was little of that and more of her whining about her everyday life - most of the problems she brought upon herself.
I honestly didn't really care overly much about Cordelia - she's not very likable. And the parts with her bff and her boyfriend were repetitive. I also didn't believe the relationship or attraction between Cordelia and Mr. Smiley. What was even the point of that relationship? She didn't actually learn that much from that connection and the relationship basically went a whole lot of nowhere. Seemed unnecessary.
I don't think I'll remember much about the plot details after a few months. If you want a morally gray serial killer who only goes after bad people, read/watch Dexter instead.
2.5 rounded up.
