I love the new pairing I don’t think I’ve read a book with just Betas. But I love Cillian and Darius together you get 2 unhinged betas who would do absolutely anything for each other. Man with this author you never know which pairing you’ll get and I like that. Can’t say I ever been disappointed with her work.

Betas Unhinged: An MM Betaverse Novel
📖 377 pages
🗓️ Release: 12/05/25
✍️ N. Slater
✨ MCs: Darius, Cillian, and Mr. Shit

WOW. This book is unhinged in the best possible way.

Betas Unhinged delivered every emotion I crave as a reader—dark, obsessive, chaotic, and impossible to put down. From the very first page, I was hooked. The chemistry between these characters is feral, intense, and deliciously twisted, and the way they fit together feels both dangerous and inevitable.

N. Slater weaves together multiple tropes so seamlessly that you truly get a little bit of everything—dark romance, obsession, devotion, and absolute mayhem. The storytelling is electric, the pacing relentless, and the tension kept me on edge the entire time. I needed to know what would happen next, and stopping before the end was not an option.

The characters are beautifully written, layered, and emotionally raw, making their chaos feel earned rather than excessive. The plot is sharp, gripping, and incredibly well thought out, proving just how skilled Slater is at crafting a dark Betaverse that feels fresh and addictive.

And yes—the pet raccoon? An unexpected gem that added charm, depth, and just the right amount of chaos to an already rich story.

This book didn’t just meet my expectations—it blew straight past them. I am beyond excited to see where this series goes next, because if this is only the beginning, I am absolutely locked in.

🔥 Highly recommend if you love dark MM, obsessive Betas, and beautifully written madness.

I don't know which part one me over. The bunny ears, the absolute simp of a serial killer, dressing up a raccoon or Mr. Shit in general. This was a full on roller coaster and this time it wasn't an emotional one. I loved that through out the whole thing, I had no clue what was going to happen with the case! It was so good! I love that we got povs from the detectives as well. It was so interesting to read. I highly recommend it if you like a dash of omegaverse sprinkled into your chaos.

loved the betas and the raccoon comedic timing. I do think this isn’t exactly the book if you aren’t into serial killers, but luckily I don’t mind. I loved the fact there’s no 3rd act break up💖

Did Not Finish
February 12, 2026
Dnf at 69%

I tried reallllly hard with this one. It was on the Black History Month bingo card on the mm romance subreddit. I'd seen this author before and I love omegaverse so I figured it would be a good place to start, but I just can't go on.

There wasn't necessarily anything wrong with the actual writing but the plot was wild in such a way that I had to tell myself to think of everyone as an alien species - a species that talks and reacts differently than I would expect any other person to. But even that didn't work.

The omegaverse element was barely used. Characters were identified by their designation but it didn't seem apparent how they were different to one another or why it mattered in society. As betas, the MCs don't have much in the way of things like slick and knots (idk if that even exists in this universe anyway) but there wasn't much explanation of why designations matter then. If that aspect had been removed, the story would've been exactly the same - so why use it?

The serial killer bits were definitely unhinged but I can't complain because... it says so in the title. But it was more descriptive than I had anticipated. Not sure when I became squeamish (I used to read a ton of horror) but apparently I am now and I had to skim the killing parts.

The real disappointment was in the shallowness and confusing/contradicting nature of the plot. It felt like the author sometimes forgot what they had said about something and then made it seem like it had always been a big deal later even when it hadn't come up before. Things felt sort of shoved in out of nowhere or too convenient or just wildly out of sync with reality.

I liked the dynamic between the MCs mostly because I like D/s dynamics especially with a Dom who is more the Daddy/caring type who just wants to spoil and care for the sub MC (this is NOT Daddy kink, he's just that sort of MC). Their dynamic does not make up for the rest of it though and the sex scenes felt really rushed which means the smut couldn't even cover.

And then there was the raccoon. I saw it come up in reviews when I did a brief look through but I didn't know what to expect. This was another area where obviously disbelief needed to be suspended and I guess, sure, I'm into the idea of a serial killer who wears bunny slippers and has a pet raccoon who he dresses up. Why not. It was slightly more believable than other parts so might as well.

This book just wasn't for me and I could probably 2 star it but I didn't finish it and I don't need to bring it down. Others seemed to be able to go with it more than I could.

Pet names: KITTEN!!! (best part of the book, honestly)

"I'm going to make a mess of you," he says, his breath hot against my ear.


"I don't want to think for a little while," I say, the admission almost freeing. This is dangerous as fuck but if I’m already in this deep, how bad could it be? Cillian's expression softens for just a moment before that hungry grin returns. "Oh, you're going to be perfect, aren't you?"


I've never let anyone have that kind of power over me. I've always been the one in charge, maintaining control even in my most intimate moments. But Cillian just took it. And I let him. And it felt like coming home in a way I've never experienced before.


"He's a good partner in crime. Loyal, vicious when necessary, and excellent at being a distraction. Plus he’s kind of cute." I look at the raccoon, at its blood-matted fur and judgmental expression. A partner in crime. Of course Cillian has a murder raccoon.


"You're staring," Darius says without turning around. "You're worth staring at."


"You're mine," Cillian says, his voice rough with restraint. "Say it." "Yours." The word comes out broken. "I'm yours."


Murder, bath, cuddles, sex. A perfect date night by anyone's standards. Well. By our standards, anyway.


I am his and he is mine, two monsters who found each other in the dark and decided to stop pretending to be human. Whatever comes next, whatever challenges we face, we'll face them together.

Mr. $hit is the best

Mr. S*** is literally the best thing ever. He's adorable and he's cute. And oh my goodness, the scene where he's putting on the slippers absolutely adorable.

That being said, this book was just not the yum to my yuck or whatever the phrase is? It was just like the title states- crazy. I think it's more like and this is a bit of a spoiler. I guess I'm just not much of a fan of like people needlessly dying and a lot of it. Just kind of was like that. I mean it's nothing against the book. It's just a feature that really isn't a thing for me and that's fine. Everybody has those.

I'm interested to see where this cliffhanger goes where the story continues because obviously there's more going on. Is there an organization? Is there not an organization? Who's the actual Mastermind pulling the strings? We found another Marcus which is cool. I think I've read one other book that has the Marcus in it so I need to go read the other ones.

Again, don't like take me not caring for all of the things of this book for not liking this book or liking this author. This is legitimately, one of my favorite authors right now and I love reading all of her work and I plan on going through her entire repertoire eventually. She has quite a few books. I like the Dynamics between the characters. They're quirky and fun.

Going into the science side of things, Miss chemist. What exactly is this chemical? That's decontaminating the crime scenes and denaturing the DNA so that it can't be tested? Cuz typically that's just sodium hypochlorite (aka bleach) but surely if it was bleach people would notice the smell right? Like even if you're doing PCR and you use DNA away. It's literally just like low concentration bleach because as we know stuff like alcohol just fixes the DNA in place and something like a peroxide is just super reactive and not really sustainable. I mean it is but you know anyways I'm just rambling because I told this author that when I reviewed their books from now on I'm going to nitpick their science stuff because I can. <3 so here's book number one since the start of me reviewing the science stuff. On to the next adventure.

Ultimately wasn't my jam.
Starts out with a pretty good storyline and some absolutely unhinged Betas - as the title would suggest. One of them is a psycho stalker who is obsessed with the other, and the other Beta is hiding his darker side and only lets that part of himself out to play occasionally. But his Beta stalker witnesses that side of him and it only makes him more obsessed. Convincing the repressed Beta that he's his though is another story.
There was definitely a slow burn element to the story and it wasn't as spicy as it was made out to be. It does have some somnophilia and cock warming, as well as kind of dominant/submissive roles that were out of the norm for at least one of the characters. There are more scenes that are eluded to than there are on page. The ones that were on page were pretty decent, I would give it a 2.5/5 peppers on the spice scale.
What I didn't love about the book was that it kind of turned into a thriller/murder mystery story, but the reader knows who the murderer is and are watching other side characters try and figure things out. These Betas aren't like "good" killers where they're vigilantes who are getting rid of terrible figures. They enjoy killing others and base their targets on things like who irritated them most recently, or who is currently making their lives difficult. And for the amount of murdering that goes on, you'd think they would be better at cleaning up after themselves or be more careful. It's clear that one of them is going to be caught at some point in the near future and the nonchalant "oh well" attitude they both have about it is weird to me. I assumed that neither one of them would be discovered and they would get away with it. But the open ended not knowing if they will get caught and other characters having a point to prove by capturing them does lend itself to other stories in this particular story. I just won't be reading them.
While the author talks about Alphas and Omegas in passing, this story was only about Betas, so I personally wouldn't categorize it as being part of the Omegaverse.

Not mad I read it, but won't be continuing on in the series.

Two killers mate bond, cause chaos with raccoon

What does one town, a business accountant beta, an obsessesd IT beta, raccoon, and a bunch of murders have in common? Everything, absolutely everything. By day Darious is a corporate accountant
Cillian is an It consultant whondoes odd jobs, and by night? Both are serial killers, with varying styles. Cillian is obsessed with Darius and has somehow adopted a raccoon as a pet.
This is a highly unhinged dark romance comedy featuring two male betas, who are mates. I can get behind the fact that 9/10 times their victims are not good people, bullies, criminals that got away with things they shouldn't, or people who like to hurt others. With the exception of one victim, not to upset on the others. The protective, love and devotion cilliann shows along with the intelligence in his foreplanning make him a highly interesting character to follow.

A M/M omegaverse romance between 2 serial killer betas, yes I did 100% jump into this.
Cillian is a chaotic ball of unhinged devotion, who will kill for his beta and protect him at all costs. Stalking is his middle name, but he is fiercely protective and happy to give his beta anything he needs, including covering up his crimes, and removing threats.
Don't get me started on the adorable pet sidekick and mini killer raccoon, and the outfits! Loved the humour and crazy interactions, he fit their insane family dynamic in the best way.
I loved the way Darius falls into the unexpected relationship and care of Cillian, and how he is finally seen and appreciated as he is.
I also enjoyed the switch up in POV's including snippets from the detectives on the hunt for the killers, and seeing the complex web grow.

Excellent and interesting super dark romance

I loved this one (not a surprise since N. Slater writes fantastic omegaverse stories), and I could not get enough of these MCs. I had no idea how much I needed unhinged serial unaliver betas in my life, but here we are! (And two beta MCs is so fun to me!)

This book is pitch black, and both MCs are without morals, so don't expect any kind of redemption arc. Personally, that's why I love stories like this so much. Even bad guys need unconditional love sometimes. 😅

The spice is top tier, and it's honestly fairly low angst, but you definitely ought to check your TWs/CWs before reading.

Absolutely recommend this one!

I received an Advanced Reader Copy.

I have to admit the raccoon was a huge comedic edition to the story. He had me cracking up the whole time. He kind of reminded me of a toddler in a way. Now Darius and Cillian were definitely a trip. Darius was more controlled while Cillian was just an adorable psychopath who would do anything for his beta. Though, I really loved how calculated and one step ahead he had been especially towards the end. Violence was truly their love language. I also loved the way Darius surrendered so beautifully for Cillian. HFN, I look forward to the next book.

Hilariously unhinged

Murderous raccoon? Check. Obsessed over the top stalker/serial killer beta? Check. A suffocated by daily life serial killer who wants real connection & to be seen? Check. Molotov cocktail of the most delicious variety, and as we all know, variety is the spice of life hahaha

Okay, this is my first book from this author and I LOVED IT! Serial killer boyfriends/mates, omegaverse (beta/beta), stalking, obsession, murder, and a friggin raccoon THAT WEARS SWEATERS!!! This was steamy and funny for something with darker subject matter and it was perfect. Mr. Shit IS the shit and I love how lovable and unhinged Cillian is!

Pet Raccoon!

I loved this book. The pet raccoon added something extra to the book that really tied it together. I love when unhinged people meet their other half and can be who they are and be loved.

As always, no spoilers.

Thoroughly fucking enjoyed this book. Never would guess half the stuff, happy how it all ended. Loved Mr Shit. The shenanigans. The banter. The matching PJs with the duck slippers. 10/10.

I forget this is omegaverse (or Betaverse) because they're both Betas and don't have the same problems as alphas and omegas do with the pheromones, and the heats and ruts. I was reading this as a contemporary and then remember it's Betaverse when mates and mate bonds are brought up.

This was a game of predator and bigger predator. The cat and mouse (stalking) game that Cillian was playing with Darius in the beginning had me thinking there was only 2 killers in this small town, but then we meet another mysterious one later on. The detectives being so persistent with Darius had me on edge, and I was wondering how they were going to get away from things.

Also Mr. Shit was so cute and helpful (at times). Perfect name for him and the chibi character of him at the top of each chapter is adorable.

The ending seems to connect to the next book, so I'm excited to see how it goes and if we'll see Darius and Cillian again.

I know this book is likely not going to be for everyone. Why?
1. They are murderers and not necessarily just for the good of the town. They like to murder.
2. While this take place in an omegaverse world with A/B/O secondary sexes, this story focuses only on Betas.
With that said, this is exactly why I liked this book!
1. They are unhinged. And they're also obsessed with each other...even if one of them tries not to be. Plus they have their unhinged racoon to go with it. (Seriously, he was my favorite.)
2. The whole point of the Beta Accepted series is that the Betas finally get the spotlight. They still have to deal with dynamics, but at the end of the day they don't need a Beta or Alpha to feel needed, wanted, or to find the perfect mate.
This has just enough comedic relief to make the dark romance aspect not feel as overwhelming and I would definitely read more in this universe!!

This is one of my favorite books that I have ever read. I was hooked from the beginning, and it was so entertaining. There was romance, a bit of mystery, and a whole lot of chaos. Mr. Shit is the best character, no arguments. This is a dark romance done

I’ve read this author before, and they do a good mix of MM, MM+ and also books that involve an FMC. So a good variety to pick from.

Now I’m an OV fan but don’t read mpreg so it’s always great to find books that meet this request. Also, here betas are the main focus - which is quite rare given normally Alphas and Omegas take precedence in OV.

If you’re expecting some form of ‘I’ve turned a new leaf and will stop killing people’ then you won’t get that here. Nor are they vigilante killers. They simple kill people who annoy them or get in the way of their plans. I’m fine with that, there’s no killing by them of kids or animals, which is my line.

We have the most adorable side kick in Mr Shit, a raccoon, who Cillian accidentally adopts and then provides with outfits that Mr Shit loves (squeaky duck slippers anyone?!). He features throughout and was such a great addition. Having Cillian talk to him and involve him in stalking Darius just fun to read.

Both Cillian and Darius are well suited, they just work - ignoring the whole serial killer share interests - and we get to watch Darius fall for Cillian after being wonderfully confused (and stressed) about why Cillian could possibly like him, given he’s a killer. We get excellent tension as to the police sniffing around Darius for his crimes and a nice little twist that I didn’t see coming.

There’s not a huge number of sex scenes but I felt the number we had was amble for the length of the book. The sex scenes were very hot.

We are left with a set up for more books in this series and I’m looking forward to the next MM one.
