PoisonVerse
Anarchy
Inside Anarchy, the strong take what they want. It’s the most secure prison for feral alphas on the continent. No cameras. No guards. No laws.
And I’m the first female omega to be locked inside.
Taught that I’m sinful and broken, I’ve been forced to suffer my heats alone. A penance—so maybe, one day, I would be worthy of good alphas. But one mistake destroyed that fragile bargain, and they dropped me down here—a touch-starved omega trapped in a prison of beasts.
I should have died the first night. But instead of being torn apart, I found something I never believed I would have—mates.
Traded from saints to sinners, I expected damnation, but Phantom, Karma, Vandle, and Sin don’t care how much atonement I’d paid before they saved me.
Instead, I was claimed. Shielded. And they are teaching me worship like I've never seen.
Their chance at freedom is coming soon, but Anarchy devours what is sacred, and my pack has a problem: in a prison where omegas are currency, our pack has two.
And we have ten days to survive in a prison full of feral alphas who would kill my mates and keep me caged here forever.
This book is a MFMMM why choose. This book has a double omega dynamic to it, but the male omega is not with the alphas in the main story. It can be read as a standalone but exists in the larger PoisonVerse Universe!

Thank you to Marie Mackay for sending me an eARC in exchange for my honest review, and for having allowed me to continue in her alpha reading team.
Another banger from my favorite Omegaverse author, and this time packing a punch with another fellow author. I admit, I was a little apprehensive to have Marie co-write with Olivia as I personally didn't enjoy Pack of Lies. But this duo worked great together. There was an excellent balance in each other's writing strength that helped the story flow nicely, despite it being lighter than Marie's usual works.
The characters were well distributed and written. You could tell for the most part who wrote who and the way it was split was perfect. Sin is definitely up to Marie's strength and I adored how broken, hurt, defensive, and fiercely protective he was. All throughout the only thing I wanted was for him to be free so that he could finally heal and find himself. Crescent I also adored for being his cute ball of hurt that just wanted to be loved and belong somewhere. Karma and Phantom sometimes felt too similar to me in terms of voice, but I still loved their dynamics especially concerning how they approached Crescent. Though I do lowkey think that there was a preference for Sin x Crescent compared to the other alphas, so I would've liked not to have such an apparent favoritism displayed.
The story itself was rather light in the sense that, compared to the usually heavy, dark themes that characterize Marie, this one only had tension from surviving Anarchy until appeal day with the added fear and trauma that lingered from the character's inner demons. Regardless, I felt the authors did fantastic at keeping the pace going while also having the pack navigate different difficult situations. This could've either felt like the story dragged out needlessly with rather repetitive mundane scenarios, or it would be too rushed. I'm interested in seeing more of Anarchy if there is a chance to expand on other packs, considering on what was hinted by the end.
What wasn't on my bingo card was the plot twist by the last part of the story. This will definitely bring some expansion into the Poisonverse and I'm very intrigued to see how that goes.
Overall, I have yet to read a Marie Mackay book I haven't liked. Anarchy was still installment to the Poisonverse. It's not on my list of favorites compared to her other works, but I definitely enjoyed it. And I love Sin with all my heart.
PS. The librarians were the cutest ever and I honestly only wished they had been present for longer.

If you love dark, gritty Omegaverse with strong emotions, Anarchy is definitely worth reading!
Crescent is an omega thrown into a prison built for feral alphas—where lawlessness isn’t just common, it’s survival. Things seem hopeless—until her scent-matched mates find her. They’re on a 10-day countdown to possible freedom with a target on their backs. Now they have to survive together long enough to make it out.
This book was so good! Crescent was so battered and traumatized, and watching her slowly start to believe she deserves love and safety had me misty-eyed more than once. Her alphas have their own trauma too, but instead of pushing her away or creating unnecessary angst, they recognize her as their salvation just as much as they are hers. Emotional maturity—we love to see it!
Even with everything she’s endured, Crescent still manages to be funny. Her inner thoughts had me smiling more than once. One line that perfectly sums her up: “I wasn’t built for running. Reading? Yes. Running? Absolutely not.” Same girl, same.
One of my favorite things about this book was that the tension wasn’t within the pack. There’s very little resistance once they realize what Crescent means to them. No dragging out their acceptance of her. No petty drama. The conflict is external, and the real story is about healing—about hurt people choosing each other and building a better future together. Watching the pack come together was honestly the most satisfying part of the whole story.
That said—this book gets gruesome. It does not hold back so, definitely read the content warnings before diving in.
I genuinely hope this becomes a full series because I am not ready to leave this world (or this pack).

Rating: 3.5 / 5 Stars
You will never catch me turning down a PoisonVerse novel. I’ve been in love with this particular universe author Marie Mackay cultivated ever since she published Havoc Killed Her Alpha and I have no doubt I’ll ride or die for it until Mackay (and her contemporaries) get tired of playing in the sandbox and move onto another.
If you’re already a fan of Mackay’s work, Anarchy hovers somewhere in between the Shattered Omega series and Havoc Killed Her Alpha in terms of darkness and intensity (I’d say Psycho Alphas is more intense, more violent, and spicier than Shattered Omega, so it doesn’t come into play here). Ironically, this book isn’t especially spicy–while this is a book that does get spicier as it goes on, the spice scenes themselves aren’t very explicit or gratuitous. There is a great deal of violence from the very start, but it’s less violent (and less descriptive) than Shattered Omega. The religious/cult trauma and the trauma from being imprisoned creates a great deal of tension both within and without the characters and propels much of the plot.
At a length of 501 pages, there does seem to be an issue with a lag in pacing during the middle third of the book, where it seems like a lot of talking is being done but not a lot of doing. While this portion of the book isn’t devoid of matters like character development and plot movement, it isn’t consistent enough to keep engagement with the book high. I could feel myself start to get a little detached. I have a feeling Mackay and Lewin were using these pages to introduce characters that might be more important in future books, and that’s fine, but it did result in what’s usually called “filler material”.
The book does end really strongly, with a fantastic last 30%. We get more PoisonVerse lore, some special guests, a really good dose of suspense, well-earned revenge, taking down some enemies, and what looks like a pack headed towards their HEA. 3.5⭐️

The Poisonverse books are absolutely amazing, but I personally think these authors have stepped up the Poisonverse with this one here. The layers that these Authors layer their story with is perfectly complex. They add backstory throughout the book when it plays the best role at dragging you further on in. This book absolutely deserves the 5 stars I'm giving it. My only issue is the same as with the rest of the Poisonverse, I'm always left wanting to read more.
Crescent is such a sweet caring omega who just doesn't understand a lot of what is going on, but that's due to what she's gone through in her life. She's a bit odd, and that lets us all know that there isn't anything wrong with being odd. She doesn't exactly love what you'd expect an omega to love, but it shows how perfect she is for her pack and how much she is clearly what they need.
Sin's character profile alone was a mind fu(k of its own. He's so complex and caring throughout, his relationship with Crescent is unique and perfect. The character development with him towards the end… no spoilers, but dang, do I want more of those red eyes!
Karma was the only person besides Crescent who had their own highlighted color, I just love him so much. He's definitely one of those characters that caught my attention, and I was hooked.
Phantom, you can just tell he holds the weight of everyone on his shoulders. He's definitely the one who seems to be able to hold his head on his shoulders, more clearly putting his pack first.
Vander, oh Vander… I absolutely loved when he came into play in the story! The way he understands and knows more than people realize. He's constantly watching and planning ahead.
These four are absolutely the perfect pack for Crescent.

4.25 stars. This long story is quintuple POV, well written and edited, and a dark, spicy, action packed, prison survival, omegaverse reverse harem romance between Crescent, the female omega lead raised in a cult and dropped into a lawless prison to punish her and make her disappear, and the Banner pack who scoop her up and save her: Sin, the male omega-presenting lead, Phantom, the most stable alpha lead, Karma, the male alpha lead who uses fighting to keep himself somewhat sane, and Vandle, the male alpha pack lead and seer, who hasn’t been sane prior to Crescent’s arrival. I adored the care the males took with Crescent, even in the dark, hard environment they found themselves in. I empathised with the brainwashing and indoctrination Crescent had been raised with, and appreciated the gentle way the males worked to teach her different ways. I enjoyed her growing confidence and personality. I enjoyed Sin’s strength and resilience, and was amused by his shock as revelations about him emerged. I appreciated the careful persona he’d cultivated in the prison, and the contribution he made to his pack. I enjoyed Karma’s self control, even in the midst of rut, and the effort he made to provide Crescent with the things she needed. I enjoyed Phantom’s protectiveness and his future focus. I enjoyed Vandle’s reawakening to sanity and his growing craftiness. I adored the way they worked together as a pack. I enjoyed the spicy intimate moments. I enjoyed the happy for now ending and am curious whether the authors plan to do anything more here.
I received a complimentary copy from the author and this is my voluntary honest review.

Things to note:
-This was an ARC COPY review
-Anything PoisonVerse I've learned is never not amazing.
-I finished this book the day I got the ARC
I usually do or more likely can't stop myself, from writing a review with spoilers. So this time I'm not (a very hard thing for me to do) and I will only say these pieces of advice:
1) if you've never read a PosionVerse let alone an omegaverse book DON'T START HERE!
(no there will be no context as to why, but why you might ask because SPOILERS beyond you wildest dreams. But I would %100 not start the PosionVerse with this book... Again spoilers. Come thank me later.)
2) read the trigger warnings
3) if you've done the two above already and still want to read this book... DO IT! Like I said I've so far never not liked a book by Marie Mackay, and yet again I was not disappointed.
4) still not convinced that's ok. Trigger warnings are there for a reason.... Still waiting to give it a try... Do It. Read It. Don't just trust me read more reviews, look into the PosionVerse and omegaverse. Take everything I said with a grain of salt either way I loved this book and can't wait for more.
Thank you Marie Mackay for the ARC copy and I can't wait to see more PosionVerse in the future.
I do apologize if this is not want you want to see in a review... So I challenge the people who do read this book... After you've read it, review or no review come tell me if you could write a no spoilers review and why... Or more likely how. And if this book blow your mind like it did mine.

When you survive 3 years in anarchy for your second chance....
Crescent, a female omega, arrives at Anarchy and no one knows why - female omegas aren't allowed. Anarchy is only for alphas who are feral that ask to be sent there. And after 3 years, they have a chance to appeal for freedom. For Vandle, Phantom, Karma, and Sin, that chance is coming soon, only 10 days away. So why when they are so close, does Sin decide to do something crazy and claim this omega for himself and his pack. They've just put a target on theri backs. Crescent, she doesn't know the ins and outs of the world, even most of her designation knowledge of being an omega is wrong since growing up in a church cult will do that to you. Now that she's been thrown down into Anarchy, and claimed by a pack, she needs to figure out how to survive and get a handle on her instincts since she's been told her whole life they're wrong.
This story is gritty, lethal, and dark because they things that happen in Anarchy for the packs to survive will curl your toes. And now, with their possible release upon appeal moving closer, things are kicking up into high stakes since there are other residents that don't want them to leave. It's a battle for survival with a few feral alphas in the pack.
I very much appreciate the epilogues and sneak peeks into the packs life after too. And I hope if there'a an upcomign release, we get to see more of this pack and the Kingsman pack - I want them to take down some of these scientists and elites.

SPOILERS AHEAD SPOILERS AHEAD
Firstly, after reading i cannot wait for a special edition because I desperately want this on my shelf. I also want to thank the authors because before I found them I still thought omegaverse type books were restricted to wattpad and Tumblr. Imagine my surprise when I found authors that made thrilling plots and an amazing universe to accompany such a beastiel as well as smutty genre.
SPOILERS HERE
I loved that we went full circle from Shattered omega where Vandle was first mentioned. I'm also ecstatic about the new designation introduction! It feels absolutely perfect the way Sigma was portrayed and built into the bones of the universe. I dont know if any of the authors involved have planned it but with the addition of Sigmas I can really envision a great big physical or social war that either breaks or truly reforms not only the institute but also how society views designations. I know there are so many books already but as a reader, I feel like there's so much more in store for us! I'm on the edge of my seat for a second book to Anarchy or at the very least, another book in the poisonverse! So yeah, thats how this book made me feel. Xoxo

I enjoyed Anarchy a lot, as I do with every PoisonVerse book as all the PoisonVerse authors are incredible. This book was very unique in its setting. I had not read an Omegaverse book set in a prison before this one and I enjoyed the different situations the setting was able to provide. The cage scene was glorious and I loved Crescent’s nesting habits.
In terms of characters, I enjoyed Crescent but she’s not my favorite omega from the PoisonVerse. Thistle and Havoc are still split for that title for me, but having an omega so innocent and soft was fun with such a harsh setting and intense alphas. It made for a unique dynamic and a lot of fun scenes. Out of the other characters, Sin is my favorite. He’s fun, intense, and incredibly sexy. Also the dynamic between him and Crescent is so cute and I enjoyed reading every scene between them.
The pacing was good, the writing was phenomenal like it always is with Marie and Olivia, and the spice was hot and fun. I was hoping for a bit more intensity in the spicy scenes due to the nature of the prison, but I did enjoy the scenes we received! Overall, an amazing read and one I would recommend. 10/10, I hope we get more!

I loved this book! 5/5 for me. I’m a big fan of the poisonverse and this book is no exception!
The majority of the book takes place in a prison setting. There are definitely dark things that happen but I didn’t find this book as dark as the shattered omega series. The FMC is very soft and definitely naive. She makes some frustrating decisions throughout the book but it is almost certainly due to where she came from and what she had been through. Shes very lovable and sweet though. All of the characters are struggling from their different dark pasts but they all have growth throughout.
There’s an absolutely surprising twist that happens! I knew something was up but all of my guesses were completely incorrect and I loved it!
Make sure to read the content warning by the authors at the beginning of the book if you have anything you might not want to see on page!
I received this book as an ARC from the authors but my opinion is based on the book itself. To be fair I have loved every book I’ve read by Marie Mackay and this is probably my 6th or 7th book.

Just want to say, definitely pay attention to the trigger warnings if uncomfortable. Not too graphic for some of them but better to be safe!
This was another winner for me in the PoisonVerse! I couldn't put it down once I started (unless life made me: boo!). Crescent was the sweetest with a perchance of pickpocketing keys which I loved. The whole dynamic and past of Sin, Vandle, Karma and Phantom was great and enjoyed how their relationships got better and stabilised as the book went on. Sin and Crescent are just too cute together. I loved Karma's slight unhinged craziness, phantom's seriousness bordering on being the parent figure of the pack and Vandle's relaxed nature when it came to addressing the "keys" incident.
I would love to learn more about the library pack and maybe get a glimpse into Liam's fate in the prison! Can't recommend this new addition to the PoisonVerse enough and looking forward to the next one!

Review of advance copy
"I had two pillars where there had once been one. My pack- the place I was safe. The alphas I was supposed to protect. And her- the most precious creature on the planet."

Whether you're a fan already of the Poisonverse or it is a completely new world, this will not disappoint. This book kicks off with some trauma, goes straight into action, and slowly eases you into the spicy stuff. This is a very plot heavy story following Crescent and her alphas into the underground depths of Anarchy. Just the sound of that should tell you, things down there will be dark and dangerous. Crescent comes from a difficult place and ends up with Sin, Karma, Phantom, and Vandle, who each have strong and different personalities, and Crescent may have some quirks of her own. I really enjoyed these characters and their story.

Marie Mackay and Olivia Lewin make for a literary power duo. The setting of this book, a prison for especially feral alphas where a lot of very unsavoury things happen, was perfect. Crescent is a gold pack omega with *severe* religious trauma, and when she gets dropped into Anarchy, Sin takes an immediate liking to her. I loved this pack, they’re somehow dysfunctional in a very functional way and they make a really good combo. I loved the suspense of the setting combined with the chemistry between Crescent and her men. The non-traditional omegaverse additions due to alpha and omega experiments really add a lot to the story as well. You cannot help but root for them to have their happily ever after outside Anarchy, to have them know joy and peace and safety. I loved this story and their ending fit them so well!

♾️🌟 For Crescent and her men at anarchy, the lawless prison under the Vaults.
Our touch starved Omega FMC Crescent was punished by the cult Church organization that preys on vulnerable gold pack naive Omegas. She was thrown into almost certain death with a heat accelerant in her veins, to son of the most dangerous Alphas. She meets Sin first, with his red eyes and devil may care attitude and it opens up her world to devastatingly handsome alphas of his pack. As they race across the clock to be released, will they all make it out alive?
Tropes:
Mfmmm
Double Omega
Hurt/comfort
Unique nesting
Sweet but Feral Pack; Available on February 16th on KU I love these authors!! They really know how to write an OV I’m obsessed 💞

It's in the Poisonverse series and is absolutely phenomenal. It features double omegas, one female, one male but no ⚔️. Crescent the fmc is sent to Anarchy (part of the Cimmerian Vaults Prison) as a punishment for something completely out of her control. Thankfully the rabid, feral lawless alphas are unable to claim her when Sin (the male omega...) steps in and claims her for his pack. Their pack is 10 days away from an Appeal hearing which could see them freed. But a feral pack lead, a partially feral packmate and other packs wanting what's theirs means it might just be a fight to even make it to the appeal, let alone to be cleared and released. The world building is phenomenal, and the characters are fabulous. I adore Sin but Karma has my gooey heart. I hope there will be other books featured in Anarchy. I'd really love to see what happens for some of the others there.

This book!!
If you like omegaverse books then this book is a must read! And if you don’t know if you like omegaverse books but love a why choose that has lots of suspense, a gripping plot and men who are totally obsessed with their girl, then you HAVE to pick this book up.
I loved everything about this, it was dark and gritty, and the story kept me on the edge of my seat. There was a bit of insta love, but that is fairly common with OV books, however I felt like this was insta love done right. There is no bullying in this book between the main characters which I also liked.
This book was long, but at no point was I bored or wishing it was shorter. This was perfect. I honestly wish I could read it again for the first time.

This is set in the poisonverse series, I really liked the idea of the prison setting and dropping an Omega in to stir up trouble amongst all the inmates.
I also loved that all the pack were instantly drawn to her when she came in a d instantly knew she was theirs.
Crescent drawn to Sin, Vandle, Phantom and Karma definitely put a big target on their back, but I loved how she needed her items for the nest. Spicing was spicing, and there was a lot of possessiveness from certain people in the pack.
I love Marie and Olivia's stories and this one started off really well but I felt it went on longer than it needed to be and I was starting to lose interest before the end.
Im glad Crescent and her pack got their HEA they deserved it.

Crescent was raised in a cult that told her that her golden eyes were the sign of a sinful nature, and that she could corrupt any alpha with her touch.
Thrown into a hellish alpha prison known as Anarchy, she wasn’t intended to survive — much less meet her scent matches.
Sin, Phantom, and Karma are just trying to make it 10 more days until their appeal — their one chance to escape Anarchy, which would otherwise be a life sentence.
The last thing they expected was to have a surprise omega dumped in their laps, especially since this brings deadly resentments in the prison to the fore. They need to make alliances, fast, or else this gift of a mate will prove to be fatal for all of them.

Within a corrupt society,the unwanted and the undesireable are thrown into Anarchy,a prison only for feral alphas.
But the rich and powerful can get away with anything and that's how Crescent finds herself in Anarchy.
She's sweet and idiocrined by a cult and as soon she gets thrown into Anarchy she caughts the eye of Sin ,a red-eyed omega(or we think that).
Sin and his pack(three alphas) connect right away with her .
They have ten days until the hearing ,and if they can prove they're sane ,a chance at freedom.
They only have to survive....
A well written omegaverse with a rich and complex plot and characters broken and flawed but that steal your heart from the first word to the perfect ending.
There's a lot of sensitive themes ,so check the TW before.

ARC received in exchange for an honest review.
I was so excited to get the opportunity to get my hands on Anarchy early, and it did not disappoint.
I love the PoisonVerse universe, but they do occasionally get a bit dark for me, however this struck a perfect middle ground.
The premise of the book was certainly dark, borderline dystopian, but the relationship itself was not. It was plagued by the surroundings, and the MC's traumatic pasts, but the characters really worked hard to overcome this.
It was mysterious and suspenseful, but still made plenty of time for relationships to develop.
I also loved getting more insights into the mysteries institute.

I love the poisonverse series. And this one is no exception. I loved Crescent’s story. Getting dropped into a prison full of feral and ruthless alphas. Finding a pack and a way to survive seems impossible.
There is a lot going on in this story. Feral alphas, prison politics, religious trauma and more. It was a fast paced and exciting story.
Each character give so much to the storyline and pack vibes. It’s a unique set up. And if you’ve read other poisonverse novels there are a lot of Easter eggs and tie ins which I really enjoyed.
Definitely recommend grabbing this one!
I received an ARC for free. I am voluntarily leaving this review.

I really loved this book. I like how each character had their own relationships within the pack (not that kind). The pack is full of traditionally broken individuals, but so wonderful together. Possibly because of their common goal, and the forced proximity.
Karma and Phantom have such a great bond after their years stuck together and really seem to play on each others strengths. And Sin has a magnetic quality and you can feel his swagger through the page. Vandle is kind of a menace but in the best way. And of course Crescent. The reason and center of all things.
There is so much drama and danger and sweetness. I love every second and turned right back to page one the second I finished.

Anarchy by @mariemackaybooks and @olivialewinauthor.
Just finished my ARC copy of the and oh boy where do I start?
Sweet, sweet Cresent was hilarious. Her naivety mixed with curiosity was only ever going to end up in some giggle inducing scenarios. And her pack…well they were different shades of cray cray in the best possible way. I need a little Karma and Sin in my life 😏
I don’t want to give too much away but I cannot recommend this addition to the Poisonverse enough.
I’m off to find my keys….😉

I thoroughly enjoy this Poisonverse world that these authors have created. (if you haven’t read other books within this world, I recommend them!) Our omega, Crescent, was sweet and naïve, albeit a little brainwashed (think cult) and dropped into a violent prison. Her pack? Let’s just say they fit in with the PV themes of damaged auras and feral behaviors. I won’t spoil it, but there was a new “type” added to the mix so I anticipate more stories with this new thread. I liked Sin and his “abilities” so I’m looking forward to it.

I was so excited to receive an ARC for Anarchy. This book was PERFECTION from cover to cover.
Crescent is such an endearing character - she’s sweet, quirky, and naive. I loved Sin so so much, he’s probably an all time favorite character of mine from these authors. The characters are all so unique and their interactions are so fun. The last 40% of the book had me at the edge of my seat, with a delicious revenge at the end and a HEA. This book is such a satisfying, quirky read, I cannot recommend it enough.

give me more!
Anarchy has the kind of cover that draws your eye, and premise that promises big things. Lewin and Mackay deliver on that promise. They build a vibrant, deep culture within the lawless prison anarchy. Crescent is a cinnamon puff thrown to sharks, and her alphas - and omega, sin, or are willing to do whatever it takes to keep her safe. I love omegaverse for the raw primal instincts and Anarchy has probably one of the most primal alphas I’ve read. Great job from both authors to bring this story to us!

another fantastic poisonverse
So this one didn’t feel as dark as previous ones tbh and the spice was on the lower end for Mackay books. It is a completely book so standalone/no cliffhangers which I usually prefer.
Our FMC has an internal strength but a lot of internalized trauma/fawn responses from religious cult.
Our MMCs are sweet to our FMC. They are AOOA/MFMM so there is a designated Omega (male) who is pack but not active with the park intimately.
Overall a great book and the twists and turns are what keep me coming back for more!

I received an ARC copy of Anarchy, and I devoured it. I’ve loved all of the PoisonVerse novels so far, and this was no different. The sheer chaos and complexity of the pack was endlessly entertaining and kept me desperate to keep reading. I loved watching them settle into each other and seeing new relationships forming and old relationships deepening, and seeing just how wild things got in Anarchy. I will never not recommend the PoisonVerse series, and this is no exception. Thank you to Olivia and Marie for another fantastic read!

Wow what a ride. Anarchy was everything I hoped for and more! I've been hanging on the edge of my seat for this release and may have let out a little happy scream when an ARC hit my inbox. I love the entire poisonverse but I think this might be my new favourite just based on how unique it all is. The characters and pack dynamics were fabulously done and I absolutely adored Crescent. The plot had me furiously turning pages and I couldn't put it down. Easily one of my favourite reads of the year so far.
February 17, 2026
loved it! I couldn’t put the book down.
This book put me through a rollarcoaster of emotions but I absolutely loved it. I loved loved loved all crescents men. Karma and Sin are my favorite MMCs ever. But all men would do anything for there girl. Crescent is hilarious and I’m happy they were able to get there happy ending. I didn’t know how there would be 2 omegas but one of them wasn’t with the rest for the pack but Marie and Olivia did a great job working that out. I totally recommend!
