4.5***** stars


Hell, I really really liked this one.

“I’m product,” he reminded, […]
“You’re upset about that.”
“Would you like to be owned, alpha?”
“Depends on who’s offering to hold my leash.” Oberon winked and then chuckled when Fenrir glared.

“You’re nothing like what I imagined, and everything I hoped for.”

“Some might argue that I’m bad luck,” Fenrir said. “Things haven’t been easy for you since you bid on me.”
“Behave.”
“I… am?”
“I’m not mated to product from the Wardrobe, or Michelle’s throwaway. I’m mated to you.

And you know what I adored most about this book besides the thrill of both the plot and the romance? The abundance of dialogue!

Thank you to Chani for letting me see an early copy of this for proofreading!

Oh my gosh I absolutely loved this book; another scorching hot omegaverse, but with a twist! Omega Fenrir hasn’t always been an omega - born an alpha, he’s been through some truly horrendous experiments that have stripped him of his Alpha designation and forced him to be an omega. Trapped by a sinister organisation called The Wardrobe that traffics omegas and alphas, he’s forced to go undercover in rival mafia gang, The White Frost.

But it all goes wrong when Fen ends up with the wrong member of The White Frost, Oberon King. Oberon is an Alpha and high ranking member of the mafia… even if he can be a bit of a clutz. But what Oberon does know is this omega that’s practically landed in his lap is hiding secrets… but are lies Fen is telling enough to quench the desire Oberon feels for him?

I loved this pair; they have such good push and pull! And there’s something about a ditzy alpha with a totally feral omega just speaks to me on a deep level 😌 Their HEA brought me so much joy, I just love this pair!!

Whilst this isn’t as dark as some of the author’s other books, please check the trigger warnings before reading 💕

I'm really enjoying Chani's recent books and the way the dark content is now being balanced with some humour.

Oberon was pretty funny, and even though he's a possessive Alpha who takes what he wants, he was so eager to learn everything about Fen.

Fenrir was super interesting to me because his genetics blend a few of Chani's existing species as well as him being a test subject for the ongoing genetic ABO experiments, and it was really fun to see a new variant.

I'm very curious about what Levi is up to, and I did get my hopes up for a Levi and Shiloh pairing, but then I remembered Shiloh already got paired off 😭 Either way I'm eagerly anticipating the next book in this storyverse.

Fenrir lost the grandparents raising him at 14, and he landed on the street working as a grunt, and then he was taken in by Michelle who runs the Wardrobe, a place that does medical experimentation for the sake of profit, they sex traffick people. He was an alpha, but because of the experimentation, he was turned into an Omega. He's been sexually assaulted over the years as part of them trying to groom him into a role. Now, it's been about 10 years, and he is being put up for auction for his heat for the first time. He has been Michelle's favorite whipping Boy and pet, and he's been tasked with a mission to seduce and bug someone from the White Frost mafia. He longs to belong to someone, and he thinks by doing this he could earn his place with Michelle as pack as opposed to the product.

Oberon is high level White Frost mafia. He wasn't intended to be Fenrir's target, but the Omega caught his eye. He wins him in the auction, he's enamored, and he quickly decides to keep him. He claims him as his mate. But things aren't simple because Michelle wants Fenrir back, the Wardrobe and the White Frost are at odds, and Fenrir has a new dangerous mission... To take down Michelle and takeover the Wardrobe so that it's victims can either go free or choose to become employees and have protections in place.

I enjoyed this book. I liked that Fenrir was so powerful and snarky. He definitely didn't let Oberon walk over him. They had a steamy connection, they were both smart and witty, Oberon was obsessed and at times Fenrir walked him like a dog. Well done story. The author won her battle against typos in this book, I only noticed one.

Two small things I didn't enjoy. I thought the preoccupation with this weird Omega virginity (having had lots of sex, but just not being knotted) was icky and weird. And I didn't love how Fenrir always referred to people as product. It would have made more sense for him to think of them as people first.


Some notable moments:

"Ownership? Up until now, ownership had only felt like suffering, loneliness, and pain. This current sensation, while edged in the latter, was so far from suffering it was insane. There was nothing lonely about this feeling. About being locked on the alpha’s knot. Trapped in his lap. This couldn’t be ownership, because that had never felt like belonging before, and Fenrir knew better than to trust in the careless words of an alpha getting off."

"“Have you been lying here, wondering when and how I would dispose of you? Precious.” Soothing pheromones exploded into the room, practically choking Fen with their potency. “I’m your alpha. I would never. Your life is safe with me. Now your ass…well, I can’t make any promises about that, but—”"

"“You have someone vacuum a cave?” Ridiculous. “Also, if someone comes to throw out bad food, surely they could have returned the multi-slate you took.” “It slipped my mind?” “Fantastic.” “It’s no big deal.” “That I’m mated to a moron? Kind of is.”"


*FYI about steam: I rate steam based on a combination of quality & quantity. I note kink separate from steam because I don't want to underrate steamy reads that don't have much kink.

**Note about spoilers: I like to comment on the plot of a book in reviews, so I almost always mark my reviews as containing spoilers. But I try to avoid spoiling the big dramatic moments! As a reader, I personally like to know what I'm getting into before I read a book so I know more about the content and if it's to my taste/mood, so I try to give that information in my reviews for myself when I'm considering rereading and also for other readers.

[Sona · Rating 4 out of 5]

This was highly entertaining, gripping from start to finish, but not something that completely consumed my brain afterward.

The story follows Fenrir, originally born an Alpha but forcibly turned into an Omega through experimentation reducing him to a literal “product” in a world where people like him are owned, sold, and dehumanized. That premise alone sets a very dark, uncomfortable tone, and the book fully leans into it. Definitely not for everyone, but if you’re familiar with the author’s work, you know exactly what kind of intensity you’re signing up for.

Enter Oberon, a mafia figure who takes one look at Fenrir at an auction and decides he has to have him. It’s very much an instant-obsession setup but what I actually loved was how the plot unfolds from there.

You’d expect a typical power imbalance where Oberon dominates and Fenrir becomes dependent… but that’s not what happens.

Fenrir, despite everything he’s been through, is tough, resilient, and emotionally guarded. He’s not fragile — he’s survived. And in contrast, Oberon is the one who feels almost undone by his own emotions, completely gone from the start. That flip in emotional power made the relationship far more interesting than the premise suggests.

The romance takes time to settle into something mutual, with Fenrir slowly letting his guard down and that progression worked really well for me.

That said, while I enjoyed the ride a lot, it didn’t hit that “I will never recover from this” level. It was engaging, addictive, and exactly what I expect from this author but not particularly groundbreaking.

Dark, intense, and very entertaining a reliable read if you’re in the mood for morally grey obsession, power dynamics, and a surprisingly strong, unbreakable character.

[ML · Rating 4 out of 5]

This is the best of the 3 books so far in this series!

The plot was well done and I loved both MCs. Very hot together and all the pheromones and scenting was seriously 🔥🔥🔥🔥🔥🔥

Lots of high quality villains and grey heroes. Super good.

The epilogue could have been longer but we still get another book in this series so they can tie up loose ends then I guess.

I loved Oberon and all his chaotic energy. Fenrir was fun as a stabilizing influence who wasn’t a pushover.

[A Low Nicole · Rating 2 out of 5]

Yes I’m DNFing and rating, something I reserve the right to do when I really really try to read a book and just can’t do it because I can’t justify continuing to read something I’m not enjoying when there are so many other juicy and excellent books in the world.

I made it to 39% before calling it off after even the smut became boring. I have a strange relationship with Ms Chani Lynn’s books, where I kinda dig the super dark vibes but don’t really love her writing style. I think she does better when she’s depicting younger characters—the dialogue where I ended reading at between mob boss Oberon and some of his flunkies sounded like people in their early twenties who spend too much time on social media. Appropriate when writing college-aged students—intergalactic mobsters not so much. I appreciate her story arc in this series about a mafia trying to take down a sex trafficking ring—a weird and uneasy juxtaposition with her whole non-con speciality, but I’m going with it—and wish I liked this installation more.

[Readbookswithcats · Rating 5 out of 5]

This is the second novella in this series. It’s an MM, alpha/omega (no shifting), dark romance. Fenrir, an alpha, is a a product of bad experimentation. He was sold to this auction house and was forced into becoming an omega. The owner took a special interest in him and instead of pimping him out, made him into a weapon.
One auction night, he is instructed to auction off his first heat to one of the low ranking White Frost members so he can then infiltrate and plant a device to spy on them.
What is not expected was for Oberon, the richest man on Synastry, and high up in White Frost, to come. They also didn’t expect him to be so interested.
After paying $11Million for 1 heat, he is taken with Oberon. Oberon knows the omega was a spy but can’t help himself. In order to take him and keep him, he decides to bite and claim him. Now, no one could take him away.

Such a good novella! Loved the entire thing! Highly recommend!!

[True Loveislovereview · Rating 4 out of 5]

This story combines sci-fi and omegaverse.

Oberon (aka O) Ming, has the mark of the White Frost, the mafia. Watching Fenrir on the Holiday Heat auction made him bid high. The contract says one heat with the virgin omega and then return him. He’s obsessed with the mouthy omega and has other plans. No one will touch him again, only O, it’s his omega!

Fenrir was held prisoner since he was fourteen, always treated as property and as an object. Now in his twenties, he finally got his chance to get away.

O was ridiculously head over heels with Fenrir. He’s obsessed and protective of him.
A little complication here is that Fenrir’s former owner wants him back.
Because Fenrir is waaaay more than just an attractive omega.

I found this story less dark than I expected, it was really funny at times. O’s behavior towards Fenrir was absolutely endearing!

They are an evenly matched couple, I can’t spoil more.
A great read, well written and super entertaining.

[Julia Toth · Rating 5 out of 5]

I really enjoyed the story of Oberon and Fenrir. Their world is dark, but very interesting and I enjoyed getting to know more about Synestry. Oberon, despite being the Purse for the White Frost is very chaotic and kind of has his head in the clouds. Ferris on the other hand is the grounding presence that he needed. I loved Oberon's horrible jokes and the banter he had with Fenrir. I loved how Oberon followed his instincts even when he wasn't sure what was happening, but it all worked out for him in the end. I loved the bond between Oberon and Fenrir and how Oberon helped Fenrir and took care of him.

This was a fun and interesting read and I loved the journey these two took me on.

I always love the sci-fi aspects in these books. This was such an interesting read. The whole universe that Chani has created is so unique. The romance was sweet aswell as questionable at times lol. I mean if you’ve read any of her other books you would understand 🤣 It was easy to get into. You have some world building throughout that just draws you in and makes you want to know more.

Ps. She writes in dual pov 3rd person. But like well written 3rd person 👌

The best book of this entire saga, with the most interesting and different plot from previous ones, well-developed and peculiar characters, not similar to the latest books written by the author, finally one of Chani's stories like I haven't read them in a long time, one of those stories by the author that as soon as you started you had to read it all in one go without stopping, I can't wait to read about the next protagonists I hope the stories will have dynamics that are as distinctive and interesting as this last one!

THIS is why I read CLF. This story is back to the intriguing, creative, and twist-filled plotting and intensely focused, complex character connections I had come to expect from the author’s unique work and style. It’s one of her Synastry-set omegaverse reads, and the best and most developed and polished of them so far. It delivered a riveting read.

Fenrir is the kind of morally gray character you can sink your teeth into (and Oberon literally does, because that man is no fool and knows a keeper when he buys one). Betrayed by family and sold into a slave/indentured situation at age 14, he’s been tortured with experiments that changed him from an alpha into an omega, and then trained to be the owner and leader of the Wardrobe’s personal pet/weapon. Oh, the Wardrobe is an exclusive bordello/sex business, but, Fenrir isn’t there for that use really. He’s to be sold for sex just this once. If he’s successful…

He's about to be deployed to spy on his “owner” Michelle’s potential enemy, the White Frost, a planetary mafia of which Oberon is a key member and the richest, known as the Purse. Fen’s supposed to lure in a much lower level member of the White Frost, someone less risky to fool. Oberon isn’t even supposed to be at the auction in which Fen’s next heat is offered for sale as part of a “heat virgins” sale. But the bored Oberon attends on a whim…and when his eye meets Fen’s, it’s game over for Fen. Or game on. Because despite someone so high up and powerful buying the first heat in which this alpha-turned-omega will ever be penetrated, Fen has a mission, and completing it is crucial if he wants to gain the semi-autonomy he has craved ever since he was forced into this fucked up situation with no way out. Even though targeting Oberon instead of a low-level member is likely to end with Fen’s death. In that case, at least he’ll be free of the insidious Michelle’s gaslighting, manipulations, and broken promises of something better if he continues to cooperate.

The situation is fraught with peril and insanely passionate. I loved it. Oberon goes feral for Fen even before they connect physically, but doesn’t really know it until they’re in the thick of heat and he cannot help but claim him, altering both their lives irrevocably. There’s no insta-love here, but the lust is feral and hot and leads the way to develop, over the course of the twist-filled book, that fragile emotional connection that moves from wary enemies who fuck to loyal partners who will die before they give each other up. STELLAR.

The absolute craving for each other is tangible. Fen's intent to depart after this heat? Ha ha ha yeah no, never gonna happen. Ultimately Fen’s fate isn’t his own choice, but somehow, becoming Oberon’s gives him the kind of autonomy that felt viscerally satisfying and right. And the way they take down the enemies….

JUSTICE. Thank you.

Fen’s special physicality is the icing on the cake, because he’s no ordinary alpha turned omega. No, he’s something far more unique and deadly…! Very cool. Literally. Ice cold.

So many special little things…Fen’s fear of the Butcher (Fiora) and how that plays out, his thirst for vengeance, the jaded and easily bored Oberon’s claiming and fall from “this is my toy” to “I will die for him” is so satisfying. 100% will re-read.

HEA. Super dark omegaverse romance. Alpha-turned omega, unique abilities, touch him and DIE, claiming bites, heat, romantic suspense. NO OM action or drama, just villain drama and vengeance. Both men have pasts, but Fen's is majorly f'd up. Highly recommended for CLF and super dark romance fans.

My thanks to BookSirens for the ARC; this is my free and impartial opinion.

ARC Review – His Marked Omega by Chani Lynn Feener

At this point, Chani Lynn Feener could publish a grocery list and I would read it. Her omega books own me, and His Marked Omega just reaffirmed that completely.

This story is dark, obsessive, high-heat omegaverse with a mafia twist, and it absolutely delivers.

Fenrir Snow is not your typical omega. Born an alpha and forcibly stripped of his designation through brutal experimentation, he’s been reshaped into something the world wants to label as compliant and controllable. Except Fen is neither of those things. He’s sharp. He’s powerful. He’s hiding more than anyone realizes. And watching him navigate being underestimated? Delicious.

Then we get Oberon King. High-ranking White Frost mafia alpha. Confident. Dangerous. Slightly dramatic. Immediately gone the second Fen steps into his orbit.

The undercover element added so much tension, but the real magic was the dynamic. This is alpha x ex-alpha/synthetic omega, and that distinction matters. Fen still carries alpha traits, and the push and pull between them constantly keeps you questioning who is actually running the show.

Oberon gives strong “touch him and you’re done” energy, but he also has these unexpectedly soft moments that made me feral. Meanwhile Fen is rolling his eyes while secretly dismantling everything around him. The obsession escalates fast, but it feels earned. It feels inevitable.

And the possessiveness? Top tier.

This book includes dark themes such as trafficking, experimentation, violence, power play, dub-con elements, and explicit sexual content. It is very much a darker omegaverse romance, so check the author’s note for full details if you need them.

No mpreg. Guaranteed HEA. Maximum obsession.

If you love morally gray mafia alphas, powerful omegas who refuse to submit quietly, secret abilities, and a relationship where both characters are a little unhinged in the best way, this one needs to be on your list immediately.

Chani does not miss. Not once.

[Kreela · Rating 5 out of 5]

Chani deserves more attention. Her writing is excellent. The plot is what every romance lover wants. The characters are well done. And the sex is copious. What more do you want?

{omegaverse; m/m; dual pov; high steam}

“Heated Hearts Day was the one day a year when the Imperial family and their government openly recommended the use of heat inducers. The drug was legally sold at all pharmacies for a week leading up to the holiday”

Truly alien
Fenrir was the product of a successful operation that created a trans, or an omega from an alpha. In this world there were no Betas, and Omegas were either scarce or not fertile, so lab experiments were desirable to increase the population.

Michelle was Fenrir’s keeper. She owned the company that converted him, and her pheromones restored his sanity. “She was both his jailer and his savior, a cosmic joke that wasn’t lost on him.”

Auctioned off on the holiday for a single heat, Fenrir was secretly on a mission to implant spyware on the competition, but he captured the attention of the wrong alpha.

It was a rich guy/poor boy romance, or a romance involving a tortured lab rat. The story felt a bit like a superhero comic with the action, and both men were capable.

The Romance:

“The alpha’s pheromones were intoxicating. Briny with a hint of pine.”
“Can you seriously not keep it in your pants for one afternoon?” Fenrir sounded annoyed—“

Quick thoughts:
-there’s a lot of sex
-the anatomy seems to include both female and male parts, so a female could enjoy reading about the sex. I am not sure about men, though.
-fluids
-chess game and talking during the act
-MM
-mating bite
-banter
-Precious? What an odd endearment for a guy

I received this ARC ages ago, but was immediately delayed due to an obligation that took up all free time. I’ve been on the edge of my seat and avoiding both Goodreads and Patreon in an effort to swerve spoilers. Insomnia had me starting this after waking at 3am…yesterday, technically, and I have no regrets.

Now, I did have to work yesterday and do other non-book things yesternight, so it is now 1:30am and the missing sleep hours have caught up, SO, this review is gonna be rill brief, but still…true? No, valid. No…uhm…well, it seems my words have gone on strike due to unfair working conditions. *googles arc phrase I’m supposed to say*

Voluntary! My review is voluntary and I’m writing it because it’s honest and not bribed out of me. *cough*. moving on.

This book was really g.d. cute. Oberon was, dare I say, a sweet lovable simp angel merd3r puppy who I love. He did so very right by Fen :’)

An alpha mafioso who’s a squishy marshmallow simp for his bossy alpha-omega hybrid ice-whisperer is both a fun thing to say and also a the most adorable.

Fen’s story was a harrowing one, but wow did he win out with his scary teddy bear.

I only dropped a star because

Spoilers under this:

I was really looking forward to more for Fen’s fat and juicy super-revenge from at least 1 of the 3 villains who destroyed his happiness, but their bits wrapped up rill quick without much mention. This might make me a bit of a villain myself, but I really wanted to see what sort of horrors Chani came up with for those 3. Shame.

Okay if I write anymore it’ll stop making sense so definitely read this. Chani makes omegaverse a whole new experience and I love that for us.

[Addison · Rating 5 out of 5]

His Marked Omega expands the omegaverse universe with a story built around ritual, obligation, and the inescapable pull of obsession. The plot centers on Fenrir Snow, who enters a structured, transactional event that quickly spirals into something far more personal when Oberon King becomes fixated on him. What begins as a controlled exchange transforms into a deeper struggle over ownership, choice, and emotional attachment. The story is driven by inevitability, as Fenrir’s attempt to survive within a system designed to use him collides with Oberon’s refusal to let him remain temporary.

Fenrir is a compelling character shaped by exploitation and resilience, carrying both trauma and determination as he tries to reclaim agency over his own body and future. His guarded nature and survival instincts make his journey emotionally engaging, especially as he begins to confront what freedom actually means to him. Oberon is commanding, relentless, and deeply possessive, with a fixation that evolves from interest into obsession. Their dynamic is intense and asymmetrical, built on pursuit, resistance, and a growing unwillingness to remain detached. The emotional tension between them is constant, driven by both attraction and control.

Chani Lynn Feener’s writing remains immersive and sensorial, emphasizing emotional intensity and atmospheric detail. The pacing is steady but charged, allowing both tension and character evolution to unfold within a contained timeframe. Overall, His Marked Omega is a dark, compelling installment that blends obsession, survival, and emotional awakening into a tightly focused romance.

[Samantha✨ [reads everythinggggg] · Rating 4 out of 5]

3.5/5⭐️ I received His Marked Omega by Chani Lynn Ferber through a Goodreads giveaway, and I want to thank the author and publisher for the opportunity to step into a completely new genre for me.

I’m not gonna lie, this book was way outside my comfort zone. Going in, I had absolutely no idea what to expect, and at first I was honestly pretty confused trying to understand the Alpha/Omega dynamics and the world itself. But once everything started clicking into place, I found myself completely pulled into it and genuinely curious about where the story was headed.

I thought the story was really entertaining, and I kept trying to piece together what was happening next, even though the ending felt a little predictable to me. Still, I had a lot of fun with it. There were moments that had me on the edge of my seat, and other moments that genuinely made my heart ache in a good way, which surprised me because I didn’t expect a book like this to hit emotionally for me.

The romance unfolds gradually, with Fenrir slowly lowering his defenses, and I really liked how naturally their connection developed over time.

While this book didn’t completely emotionally wreck me, and I did find a few moments a little repetitive, I could also understand how those scenes helped strengthen the bond between the characters.

Dark, obsessive, and full of tension, this is a great read for anyone who enjoys morally gray characters, intense power dynamics, and a romance built on devotion and possessiveness.

[maisie · Rating 5 out of 5]

Fenrir being a synthetic omega just makes this story hit differently. He’s not just vulnerable, he’s questioning his own existence and what it even means to belong.

There’s this constant undercurrent of him trying to prove he’s more than what he was created to be, and it hurt in the best way. He’s sharp, guarded, proud, and you can feel how badly he doesn’t want to be owned — even when the bond starts pulling at him.

And Oberon? The control. The intensity. The way he sees Fenrir as not just a product, not as something manufactured, but as his omega. That tension between what Fenrir believes about himself and how Oberon refuses to see him as anything less than real? I was obsessed.

Their dynamic is all sharp edges at first. Power struggles, distrust, emotional walls a mile high. Fenrir fights the bond. Oberon doesn’t back down. It’s messy and charged and so, so good. But what really got me was how the story slowly shifts from dominance and resistance to understanding and choice. It never feels easy. Every soft moment feels earned.

The angst? Immaculate. The emotional payoff? Worth it.
I finished this completely attached to Fenrir and lowkey defensive of him. Five stars, no question. I’d reread just to watch him choose himself and then choose Oberon all over again.

SO EXCITED FOR THE NEXT!

I received an advance review copy for free, and I am leaving this review voluntarily.

HIS MARKED OMEGA is the fourth book in the Beguiled Omegas series, although you can read it as a standalone.

Oberon King is known as the Purse of the White Frost, while Fenrir is simply known as Wolf. Fen has lived for many years as a Product of The Wardrobe, and has one final mission before his mistress, Michelle, says he will be claimed as Pack. Of course, you know it's not going to be straightforward!

I loved the back and forth between our two MCs, complete with their cheesy romantic one-liners and the dad jokes. That was balanced by Fenrir's heartbreaking backstory that came out in dribs and drabs. They are ably supported by a host of characters, some of whom I've heard of or met in previous books.

This is a dark romance, so it does come with trigger warnings. Please read to ensure it's safe for you. I personally didn't think it was too bad, but that's me. Use your judgment for your own mental health.

A great read that I thoroughly enjoyed and have no hesitation in recommending.

Any time Chani finishes a book, I always drop what I am doing to read it (even if I have to adult ugh). Still one of my favorite authors to read especially when it comes to dark reads. I am really enjoying the stories she is creating within the omegaverse, though I enjoy all her stories. The world is unique and very interesting to read about. I've always liked the Alpha x Alpha dynamic, even though Fen is no longer an Alpha, I loved his personality. He was headstrong and no dandy flower; but all of Chani's omegas are no push overs. I really liked the back story of Fen. It gave him an even more of an equal standing with Oberon. Though, I liked that there was a flaw in this which made it more real and not godly.

The commentary between the two (and the side characters) was also hilarious. I also liked how Fen still had trauma from every thing that was done to him and it was depicted in the story. It wasn't glossed over and or ignored.

I am still looking forward to Levi's story and also Shiloh's (but more Levi cause it's Levi).

Chani Lynn just gets better and better the more I read... And that's saying something because I was already obsessed with her work from the start 😈.

Fenrir & Oberon's story might be my new favourite (until the next one 😏) and I am obsessed with their dynamic! The entire premise of Fenrir's backstory was one I haven't read before and I LOVED every second of it. Oberon was the perfect mate for him and thankfully was as obsessed with Fen as Fen needed him to be 🥹. This has some serious hurt/comfort vibes even if there are some darker aspects.

I seriously love this new series and can't wait for Leviathan's story... And honestly any story in the future to come 😍.

Fen & Oberon were absolutely 🔥🔥 together and their spicy scenes? 🫠🥵💥 Absolute perfection in my eyes 🤣 I was SWEATING 😅. If you've loved any of Chani's books then this won't disappoint and if you love Omegaverse with a helping of dark and mysterious then you should definitely check this (and the rest of the series) out 💘.

Another Excellent Book in Chani's Omegaverse Series!

I read this as an ARC, and I absolutely adored it!

I've enjoyed every book in this series so far, but Fenrir and Oberon are my favorite characters in it. There are also Chani's staple triggers that tend to appear in most of her stories, but overall, this one is considerably more tame than some of the others.

Don't get me wrong, though... Definitely read the trigger warning page that Chani always includes because her books can be intense. However, if you love over-the-top possessive alphas and fierce omegas in a well-written, well-executed story that is deeply engaging, then you should definitely read this book.

The spice is delicious, as per usual, and the action and plot are, muah!, chef's kiss.

10/10 totally recommend. This is not your ordinary omegaverse story, and that's a very good thing!

As expected from this author, this was a great story.

Fenrir and Oberon's story was actually sweet, considering how they met and how both of them are. They got attached surprisingly fast, and Oberon was quite honest about his feelings from the start. Instead of resisting and pushing him away, Fenrir gave him a chance too. He'd always wanted to belong somewhere, so that makes sense, though.

I honestly loved that Fenrir wasn't weaker or more delicate because he was the omega in the relationship. He'd been born an alpha, and he could be lethal when he wanted. A perfect partner to Oberon, who loved his fire and dangerous nature.

I would have liked this book to be longer, but I understood that their story was over. I'm just greedy, I guess lmao

Since ‘his secret omega’, I've been hooked... And I'm not going to keep that a secret. ‘White Frost’ is fascinating, but the whole world and its planets have captivated me for a long time.
This story has earned a special place on my list of favorite books. Why? How could it not?
I love this instant attraction, especially when neither of them quite understands or wants to admit it. It's wonderful to watch the game of love and attraction unfold from the safety of your cozy blanket.
Those who like Dark will definitely get their money's worth here, while those who are more sensitive will... well, have a hard time. Nevertheless: I definitely recommend reading it, but you have to pay attention to the foreword.
Please give us more of this, Levi still needs his second chance.

Now this is not the first book I have read by this author, so I already had certain expectations. And I have to say that once again I am not disappointed. This story is about Oberon King, a mafia boss and quite a dominant boss, who has some problems with his feelings, if he has them or not of course. And then he meets Fenrir Snow. Meeting is not entirely correct, because he rents Snow for a considerable amount of money. What he doesn't know, perhaps suspects, is that Fenrir is not just anyone and that the company The Wardrobe has a major influence. Enough to create an exciting, emotional and spicy story. So I really enjoyed these two MCs from the first to the last page, who are quite evenly matched. So if this book is interesting enough, I would say a resounding YES to that.
