This started with a bang and ended with a bang! This book was good. I liked that both characters are serial killers but ONLY go after bad people! I did feel like the more we got toward the end, the more it dragged a little. I feel like it could have been 50-100 pages shorter. Hint as to why I gave this 4 ☆'s and not 5.
The couple that kills together stays together. Hazel and Fox are an ordinary married couple with a baby. Except for one small detail—they're ex-serial killers. Then Hazel gets pregnant, and they give it all up for life in the suburbs. But recently, Hazel has started to feel that itch again. When she kills someone behind Fox's back and brings the police to their door, she must do anything she can to protect her family.

Thank you, Netgellay, and Random House Publishing for the Ebook in exchange for my honest review.

I adored the premise of this books. The plot was engaging and interesting. There were also twists I didn’t see coming which I appreciated. I loved the ending. Unfortunately I could not seem to like the FMC. Honestly, the only character I really liked was the FMC’s friend Jenny.

THANKS TO THE PUBLISHER FOR THIS ARC IN EXCHANGE FOR A HONEST REVIEW.

Two serial killers who got married and now work together. Sounds like a good pitch, right? I thought the same. 
Haze and Fox both have this itch to kill bad people. Fox comes from a perfect, extra-rich white family, He doesn't have any motive to kill people except he feels good after killing good people. On the other hand, Haze grew up in foster houses, here and there, and her life experiences made her take revenge on bad men. They met and got married quickly as they fit together. After having a kid, they can't practically continue their side hobby so a break makes sense. Except, it is not easy to break habits. 

The story has potential. I really enjoyed the start and introduction of the character but once the story started progressing, it felt like nothing was progressing. The story was too slow and I was just turning pages without getting something new or interesting. It was so dragged. I felt Haze got more story time and she didn't have anything to offer, except what she was wearing and mundane things about her life. On the other side, Fox felt more interesting than her and his point of view sounded more humane. Haze was such an annoying character, she was just there having a cardboard-like personality. The story could have been so much more. The ending was another positive thing, it was interesting but at that point, I stopped feeling anything for either of the characters. Fox had a lot to tell but all of his tracks were swiftly covered in the last few pages. I have no idea, why haze started cursing a lot in a few chapters or why every character was swearing in the same pattern. For some reason, it bothered me.

Being rich and white is a heck of an alibi, almost like you can get away with murder. A Serial Killer’s Guide to Marriage by Asia Mackay hooked me from the first page. The chemistry between Haze and Fox is so irresistible that, despite their murderous past, it’s impossible not to root for them. Their personalities are incredibly likable, and the way they navigate quitting their deadly habits cold turkey is both hilarious and, in a strange way, relatable. The novel captures their struggles with this drastic life change in a way that feels genuine, and the miscommunications between them—though typical of any relationship—are elevated by their unique circumstances, resulting in plenty of laugh-out-loud moments.

What sets this book apart is its quirky tone and offbeat humour. Mackay perfectly balances suspenseful thrills and light-hearted fun, which is no small feat in a story about two former killers. It’s thrilling, yes, but also surprisingly charming. I found myself rooting for Haze to figure out how to balance her dark urges with the demands of suburban motherhood. Her character is endlessly fascinating—a fierce, unapologetic woman trying to navigate life in a completely new way. Her internal conflict and artistic outlet gave her a depth that made me glued to her journey.

Fox, meanwhile, is a refreshing twist on the “book boyfriend” trope. He’s caring, supportive, and has a softness that contrasts with their criminal past. He brings a genuine warmth to the story, and it’s easy to see why readers would fall for him. But for me, Haze truly steals the show. She’s eccentric, loud, and utterly confident—a "girl’s girl" through and through despite her limited social circle. Her unapologetic nature makes her an unforgettable character who’s as fierce as she is.

This is an exceptionally well-written blend of dark comedy, romance, and smart thriller. Mackay's unique take on love and crime had me giggling, shifting in my seat, and fully invested in this messy, murder-filled marriage. If you’re looking for a thrilling and heartwarming story, this one is a must-read!

Thanks to Asia Mackay, Random House Publishing Group - Ballantine, and NetGalley for the eARC of "A Serial Killer's Guide to Marriage." The book will be available for purchase on January 14th, 2025.

First of all, thank you to NetGalley and Asia Mackay for this ARC. This isn’t my typical genre but oh I loved it!! It felt very Mr and Mrs. Smith if you know what I mean. Dual timelines can be tricky but this was done really well. I was hooked the whole time. I would 100% recommend this book!!

First I want to thank the publisher for allowing me to receive this ARC. Overall I enjoyed this book. However, with it being categorized as satirical I expected it to be funny. There were a few jokes here and there but I felt like the story needed more. This is the first book I have ever read by Asia Mackay but I will likely be reading more from her.

Random read about a married couple that are serial killers together but go “straight” to raise their kid. But both are pretty miserable until they find an outlet…

Fun concept, very contrived storyline. Unbelievable character dialogue and the conclusion was beyond ridiculous. “Let’s tie up every loose end with a convoluted solution - and make everyone happy!”

Great book! First time reading this Author and would definitely recommend. Kept me on my toes and very curious about the outcome. Overall great book.

“A Serial Killer’s Guide to Marriage” is by Asia Mackay. This books follows married couple, Hazel and Fox, as they have hit a lull in their marriage - things are “okay” in their relationship (focus mainly on their child), but the spark just isn’t, well, sparking as much as it had in the past. In the beginning, I really liked this book - watching as Hazel struggled to balance who she was (an artist) with who she is now (a Mum) was interesting. But as the book progressed, I found myself becoming - for lack of a better word - bored because it felt like the story was dragging. I do think a few chapters could have been combined for a tighter and faster paced story - or maybe a few of the chapters regarding the past excised. I did like the different POVs. I also really like the cover of this book. I do wish that the two main characters had communicated better with each other, but the miscommunication trope is not my favorite.

Thanks NetGalley and Random House for an ARC of this book in exchange for an honest review. There are so many more of these humourous mysteries lately, and I am absolutely here for them. I get caught up in the characters and wondering what will happen next. I was not prepared for this ending. Love how the author took us in a whole different direction and made us see people differently. I would definitely recommend this book. Worth checking out when it’s published in January. A ⭐️⭐️⭐️⭐️💫read for me.

Two serial killers married to each other! This book shed a lot on some pretty typical marital problems, with two not-so-typical protagonists. We got to hear narratives from both sides. It was an enjoyable book!

A Serial Killer’s Guide to Marriage is very Dexter meets Mr. & Mrs. Smith.

I was lucky to read an ARC from NetGalley and Random House. This novel had me laughing so many times. I crushed it in two sittings and stayed up way too late because I just wanted to know what came next.

Haze and Fox are goals, and Haze’s “words of advice” at the start of each part had me cackling. So real and honest.

I received a free e-arc of this book through Netgalley. The cover is beautifully eye-catching as well as the title. The story of how Fox and Hazel both became serial killers and met was very interesting and believable. I enjoyed reading this book as the characters and the writing pulled me in. I couldn't guess the ending so that made it all the more appealing. A different kinda of read although I could definitely feel Hazel's tribulations as a SAHM.

Asia Mackay’s A Serial Killer’s Guide to Marriage brings a wildly inventive premise to life, blending sharp humor, suspense, and domestic drama into an irresistible thriller. When I picked this book up, the intriguing title alone had me curious, but the story inside offers much more than just the novelty of its name. It’s an engaging, clever read that manages to poke fun at the complexities of marriage while delivering a gripping narrative.

The protagonist, Hazel, is unlike your typical heroine. She’s a former assassin who’s settled into a life of suburban normalcy, complete with a loving husband and kids. However, life as a wife and mother hasn’t erased Hazel’s deadly past. As she tries to juggle her dual existence—taking care of her family while dodging old enemies—she's pulled back into a world of danger, secrets, and, of course, murder. The stakes rise as her personal and professional worlds begin to collide, threatening both her life and her marriage.

What really sets this book apart is the way Mackay writes Hazel. She’s both fierce and relatable, a lethal assassin who deals with the same mundane challenges many wives and mothers face—laundry, school runs, and trying to keep her marriage strong. Hazel’s voice is sharp and witty, and her inner monologue is full of humor that keeps the reader entertained even during tense or dangerous moments. The contrast between her normal domestic life and her deadly side gig adds a lot of the book’s charm and humor.

One of the strongest aspects of A Serial Killer’s Guide to Marriage is Mackay’s ability to balance the book’s darker themes with humor. The novel is full of amusing moments where Hazel’s lethal skills collide with the ordinary problems of family life. For example, she’s just as likely to be plotting how to eliminate a target as she is thinking about what to make for dinner. This contrast makes the book feel fresh and keeps the story moving at a lively pace.

However, there’s still plenty of tension to keep readers on edge. Mackay expertly builds suspense, especially as Hazel’s old life as a killer catches up with her and starts threatening the stability of her family. The action scenes are well-written and adrenaline-filled, creating moments of real excitement and danger. Hazel’s complex feelings about her past and present life add depth to the story, making her more than just an action heroine.

The novel also touches on the theme of identity—how much of our past selves we can truly leave behind. Hazel’s struggle to maintain her new life while reconciling with her old one adds an emotional layer to the book that makes it more than just a fun thriller. Her marriage, too, is at the heart of the story, and while her husband could have been explored in greater depth, the relationship dynamics offer plenty of intrigue.

That said, one of the book’s minor flaws is that some of the supporting characters, including Hazel’s husband, could have used a bit more development. While Hazel is a fully realized, multifaceted character, the rest of the cast sometimes feel like they’re playing supporting roles to her journey. But for a story as action-driven as this, it’s a small gripe.

Overall, A Serial Killer’s Guide to Marriage is a fast-paced, darkly funny novel that blends thrills with real heart. Mackay has created a unique character in Hazel—an assassin who’s trying to keep her family intact while navigating her dangerous past. The mix of humor, action, and emotional depth makes this book a fresh take on the thriller genre and a thoroughly enjoyable read.

3.5/5

Being rich and white is a heck of an alibi, almost like you can get away with murder.

Hazel & Fox are your perfect suburban couple with a perfect daughter. After spending 10 years in the honeymoon phase of their marriage, it all comes to an abrupt halt thanks to the birth of their daughter. Then Hazel breaks their pact and kills, but he deserved it, so it's fine. This book follows past and present Fox & Hazel navigating their relationships, hardships, and what makes them the way they are.

This book is outside my norm and felt a little more romance/relationship than thriller, but it did have a few nice twists my oblivious self didn't see coming.

A Serial Killers Guide to Marriage was great! I’d call it a romantic suspense. Perfect for fans of Killing Eve!

This book was amazing! Cute and funny, a great addition to murder and comedy collections (if that is a thing)

This was a lot of fun! It is a fast-paced, dark, absurd (a compliment!), and also hilarious story.

Two serial killers, married to one another and once deeply in love, now find themselves living in the suburbs and raising a child. Hazel and Fox promised they wouldn't kill anymore - or at least that's what Fox suggested and Hazel begrudgingly accepted. When Hazel breaks her promise, she begins to spiral as she tries to conceal her secret from Fox.

The premise is great and I appreciated how we got a lot of insight into Hazel and less so into Fox, even with dual perspectives. I think the ending softens the overall story and the characters but I still enjoyed the read. 3.5 stars. Recommended to anyone looking for a creative and thrilling take on a marital drama.

Thank you very much to Random House Ballantine and NetGalley for the opportunity to read a copy.

Unputdownable fast-paced read!

I thoroughly enjoyed this book, Haze and Fox had me eagerly flipping pages curious to see what kind of fiasco they would get into next.

This storyline is a Domestic Thriller Rom-Com mashup and honestly it worked really well. There are heavy and twisted moments, comical moments and really heart warming moments as well.

This is a new to me author and I can't wait to read more from her in the future. I'd definitely recommend adding this one to your TBR.

Thank you Asia Mackay, Net Galley and Random House Publishing Group- Ballantine for providing me with an ARC of this book!

This was super interesting to read and to get an insight into the minds of married serial killers! What a wild story. Thanks to NetGalley for the ARC. I was laughing and then stunned at other moments.
