Rate this book
A new path…
After Ena’s bold decision to join Ty in the Underworld, she must navigate her status as the only witch in a society of daemons. Charged with posing as his witch-slave for her own safety, she learns to embrace her dark side, all while grappling with the guilt of her decision to leave her sister and Coven behind.

A growing love…
After waiting for nine years, Ty finally has what he’s always wanted—Ena. As their trust and bond grows, Ty must grapple with his many conflicting responsibilities to his people, to Ena, and to himself. Can he have everything he wants or is hope for the future only a delusion?

An unknown future…
As Ena and Ty work together with daemon and witch allies alike, they must find a way to break the bond to Iblis, setting right that which the witches broke centuries ago. But as they uncover more about the amulet, the ritual, and the very Gods they worship, they find that everything is not as simple as it once seemed. Together, can they forge a new future, for their peoples and themselves, or will their differences forever keep them apart?

3.75 - 4 ⭐️⭐️⭐️⭐️ so rounding up! First of all, thank you to the author providing an ARC! This was a solid follow-up to book 1, & while I didn’t like it QUITE as much it still had me engrossed, staying up late reading, & rooting for everyone. Let’s get into it

PLOT
This picks up immediately after book 2 where the team must now go on a mission to the Underworld. This book has
- witches, demons, & seers
- societal power dynamics
- found family
- a somewhat unpopular trope (see spoilers if you must know)
- higher spice with some Dom/sub play


PROS
- I thoroughly enjoyed the roleplay Ena & Ty had to do when they got to the Underworld to play a political game. I found it entertaining.
- Solid found family, big fan of them! Turner is my guy.
- The last chapter was some great insight into family drama I very much liked.
- Hot spice. Ty & Ena have chemistry like whoa.
- I thoroughly enjoyed Ty’s POVs myself so this is a pro for me personally, but if you’re someone who tires of hearing the MMC lust after the FMC, you may get a little annoyed. I love it though. Tell me how hot you think your woman is.
- I still very much like our leads. They did a couple things I wish they hadn’t overall but I still just *like* them. They’re reasonable overall, which seems a rare trait sometimes.
- Very interested in Underworld politics.
- Also excited to learn more about Omnis.
- I tore through this. Much like book 1 it just had something in it that kept me turning pages. Idk if it’s the leads’ chemistry, the fun witch v. daemon dynamic, or what but I read this in less than 2 days & was up until the wee hours reading.


MIDS
- The first half of this book was essentially without conflict, so it felt slower in comparison to book 1. Now this doesn’t necessarily bother me but I do remember thinking to myself “okay so what’s gonna happen & when are we getting around to it”.


CONS
- The phrase “that makes sense” was said enough in conversations between our cast that I noticed. Basically any time anyone would figure something out, someone would respond with “that makes sense” & follow up with more info or a question. It felt repetitive how often it was used & just wasn’t necessary IMO.
- I don’t love a trope used at the end because I also wasn’t sure how it actually happened considering the thing that occurred & caused the major conflict in this book. The 2 seem diametrically opposed, so I wonder if it’s potentially not what we think it is? But for now it doesn’t seem like it should be possible.


I will def read book 3, excited for it!

3.75⭐️, 3🌶️

You guys I’m so sad but this did not pass the 2nd book curse for me 😭

It wasn’t a bad book by any means I just felt a little bored throughout most of the book. This one pretty much picks up from where we left off in the 1st book. There was quite a bit of spice just in that first 25% alone and while we did make some gains in the plot, it was definitely slow until about the 75% mark for me.

Unfortunately this book also had one of my least favorite tropes in it as well, I don’t want to name it because I don’t want to spoil anything, but it just is not one I enjoy. I did enjoy the characters still and their relationship and I definitely think this was more of a character driven book in that aspect.

There also was not a cliffhanger ending which was nice and I am interested to see what happens in the final book.

*BETA read*

Such an amazing continuation to this series!! We pick up right after the events of The Knowing Witch and I really love that this book is dual POV! Ty's chapters were absolutely some of my favorite chapters in this book!

After being reunited and slowly owning back up to their feelings, I loved in The Unknown Daemon you get to see Ena and Ty exploring their relationship both emotionally and physically.

This book is definitely darker than The Knowing Witch. Just the dynamic in Ty's home life is more painful and disturbing the more you read. You really feel the suffering that these characters ensure and you just want to root for them to survive. Steig and Turner also make more appearances in this book, which I absolutely love because Steig is definitely one of my favorite characters in this series. He's moody and broody but you can't help but love him. I really love Turner too because you get to see a little of his background story (not too much, but glimpses) and you really feel for him. I definitely can't wait for more of these two as the story goes on.

The plot is really intriguing. I found it hard to really know who was in the wrong. Like once you get down to the underworld, you know who the evil person is...but I think you also get to see the daemons who might not be so evil. Definitely not black and white.

Besides the growing plot...there were other things growing. The spice??!! The spice was spicing! It was hot, it was delicious, and I definitely could not get enough of it!

Overall, The Unknown Daemon did not disappoint! Well thought out character development, the perfect amount of pain and suffering for the plot, and I loved how loyalties and trust were tested throughout this story, because it made the yearning between Ena and Ty that much more! So many emotional scenes and so many new questions to be answered! I really love that Ena is coming to the realization that nothing is as it seems.

Definitely excited for the next book, I cannot wait to see what happens because I know it's going to be good.

overall i enjoyed this, but i felt like it dragged, especially around the 60-70% mark. i also thought there were a bit too many sex scenes (nothing wrong with them but they may have been better off replaced by something that develops the plot). i enjoyed the first book more.

i love the characters and setting a lot and i’ll definitely read the third book!

ARC Review - “Darker, hotter, and completely unputdownable.”

Okay, wow. The Unknown Daemon picks up fast and honestly? It grabbed me immediately. I was over the moon to be chosen for this ARC because I LOVED The Knowing Witch, and this sequel did not let me breathe (or sleep) I couldn’t put it down.

A few of my highlights *light spoilers ahead*

The dual POV was such a win for me. Ty’s chapters? Perfection. The man is chaos, loyalty, and longing wrapped in one painfully beautiful daemon, and I loved every second of being in his head.

Ena and Ty together? Finally. These two get the space to actually explore their pull toward one another. It never felt rushed, just the perfect, tension-filled build into, “pinch me… we’re actually together.” Their emotional growth and physical tension was everything.

I loved the darker tone of book two. Being in the Underworld adds a whole new layer of understanding to Ty’s struggles the brutality of daemon hierarchy, the pressure of what’s expected of him, the weight he carries. The politics in the underworld are murky and fascinating, you feel how much these characters have endured at the hands of Cole.

Watching Ena slowly realise how little she really knows about daemons, the gods and the balance she’s been taught her whole life was one of my favourite parts. Learning that the Underworld isn’t just “evil.” Some daemons are awful, some aren’t, and many fall somewhere in between keeps you guessing in the best way.

Ena’s role pretending to be Ty’s Witch Slave did have me bracing for tropes I normally avoid. But Parks sidesteps them all. Ena isn’t humiliated by Ty. She isn’t diminished. She’s undercover, furious, clever, and constantly calculating her next move. And the dynamic between her and Ty as they play their roles in public while unravelling each other in private? Phenomenal tension.

For me the side characters shine in this book. Steig continues to be an absolute grumpy treasure impossible not to adore especially once you see him with his kids. Turner cracks open just enough that you want more of his backstory. And Lara? My new fave. Every scene she’s in adds depth and momentum. I need more of her and Ena’s friendship in book three.

And the ending! Bless M.M. Parks for not leading us to a cruel cliffhanger. It hits that perfect sweet spot: a satisfying wrap-up to book two while clearly pointing us toward what’s next. No whiplash just a smooth, confident handoff into the next instalment.

I had such a good time reading this book, and I truly can’t wait to see where the story goes next… Demon and Witch magic sharing???

*ARC Review*

I inhaled the first book and was so excited to receive the ARC for the second.

It picks up exactly where we were left off in the Knowing Witch and we jumped right back in. I appreciate that Ena is actually clever and uses her brain regularly. She can actually make a sound choice without letting her emotions or prejudice dictate everything. I long to be as emotionally stable and rational as she is. Obviously Ty is amazing too but Ena stole my attention and honestly, no one would have survived if not for her.

I wasn't a fan of the third act break up though. It wasn't a normal response for Ena to take a cowardly way out when things got tough... which she does admit to that later on. And I know calling it "cowardly" isn't 100% fair but I'm not as evolved as Ena so here we are. Plus I've never had the shit beat out of me so what do I know? I appreciate that they both got over themselves and their self declared pity parties.

I'm also not sure how I feel about the pregnancy. Obviously they were going at it like crazy so I'm not too shocked. It was a miracle that she got her ass kicked and broke some ribs and the baby survived unharmed... but again, never had my ass kicked WHILE pregnant so who knows... I'll have to try it some time.

Guess I'll have to just read the next one to figure out how I feel. Hoping Turner gets a happy story for himself, would be nice for him to not be the third wheel/fifth wheel in the next one. And I LOVED Mel. They were a great addition. Not sure if we'll get more of them in the next book but fingers crossed 🤞🏻

The Unknown Daemon seamlessly picks up right where The Knowing Witch left off.

The dual POV is 🤌 and the growth of the characters had me turning page after page. I love a good underworld setting and this book delivered.

I look forward to the next part of Ena and Ty's journey.

Like the first book, I'd give this one a 3.8. I felt like the resolutions to the challenges faced by the characters were spoon-fed to me, and there was never a true sense of urgency or suspense. But the spicy scenes made up for it! Undecided if I'll read 3rd when it comes out.

This book was such a wild ride. There were moments of tears streaming down my face and moments I was giggling while kicking my feet. We picked up right where book one left off and went right in to the spice! I found myself worrying that this book would be too lovey dovey and get boring but boy was I wrong. The yearning was intense and I loved every second of it. I cannot wait to see what comes next for Ena and Ty.

I’ll give this book a 3.75 ⭐️ There were some parts I really liked, but other parts in the story I struggled to enjoy so let’s dive in.
Likes:
I love the addition of Ty’s POV. I felt like this brought a lot more to the overall storyline. I think it really filled in a missing piece to the first book.
I also enjoy the magic system and politics between the witches and deamons. I think it brings to the forefront how as a society we just follow along with what we have always been told without exploring why we do. I love that the main characters end up having to question this and want to build a better, kinder next generation.
We are going to need a few Turner POV chapters because his character is one of my favorites! He so friendly, funny, loyal, and sly. He is such a good character in the story.
Dislikes-
I struggle with how naive they make Ena in the book. I think she lacks the personality to be a strong female character with the role they are wanting her to play in the book. It further bothers me into her relationship with Ty as he is very powerful and “experienced”.
I thought it was weird that she didn’t understand the word Heir. It just didn’t fit or make sense. I know they were wanting to try to explain how witch and deamon culture are different, but this was a weird way to do so.
I thought the book was pretty slow moving and kind of boring until the end.
She springs a lot of fun, exciting info at the end which I wish we could have gotten more within and throughout the book.

Overall the book has potential. I think it’s going to be really interesting to see where she takes the characters with the introduction of the unknown, mysterious Omnis clan and Ty’s mother. I know some people may hate the pregnancy trope in this, but I’m actually excited to see how she uses it further in book three. Book three could easily be the best one yet in this series!
Thank you Book Sirens and the author for letting me be part of the street team and an ARC reader for this book!

She’s a spicyyyyy one 🙂‍↕️ The Knowing Witch hinted at it but The Unknown Daemon confirmed it, they are some freaky freaks y’all. All that tension and then make it forbidden 👀 and she has to be his witch slave 👀

Spice and romance aside the world is expanding and I loved learning about all the different levels of the underworld and hierarchy of daemons. The underworld kinda reminded me of the underground city in The Veiled Kingdom by Holly Renee similar spicy vibe to that too!

We also get a better understanding of the origin witchy and daemon powers. I really like that there is a reason behind the magic both in its abilities and the specific words used when casting spells.

Because of REDACTED there is this whole concept of future sight which is so fun to theorize about through the entire book and fits in so well with the witchy vibes.

Plus with that ending there is so much more room for world expansion and lore in book 3 I can’t wait to see where she takes us!

Trope List:
💙 Witches & Daemons
🖤 Forbidden Love
💙 Witch Slave

I received an eARC from Book Sirens and this is my honest review.

✌🏻Mostly dual POV
- 🤣giggling out loud moments
- 🧙witches & daemons 😈
- 🤩 warm MMC, but only for her & found family
- strong found family ❤️
- 🌶️ spicey in the first 50%
-⛓️she likes to call him "master"
- he likes to call her "viper" & "dark goddess" 🖤

Overall, this was a strong 4 star read.

The pacing of this book was slower for the first 60%, as it focused on relationship building between the MCs as well as the MFC and the MMC's friends/family. The plot does move forward in the first 60%, but not much, again because it is highly relationship focused. I did not mind this and thought it was needed to really show the WHY behind the MFC supporting both the witches and daemons. The last 40% of the book picks up pace and I could not put it down. The author did a great job provoking emotions in the reader, particularly I was rooting so hard for the MCs to convince those needed to help break the spell.

The chapter from Cole's POV (the MMC's uncle) added so much more to the story, I am grateful the author added this near the end. We got so much more information on why Cole is evil, especially in relation to the MMC's father and mother. This detail gave the story more depth and set up the next book well, since the MMC's mother will obviously be in the next book. Also, the first chapter starting from Mel's POV was interesting, but then it came full context later in the story. This was creative and gave the story a little twist.

I really enjoyed the storyline and little undertones important in real life, such as a) the diverse crew working together, as diverse teams are stronger than teams that lack diversity, b) basic rights for all, c) leadership making choices to hide knowledge and the harmful impact of that, d) the importance of choice, e) women not having to be embarrassed about their sexuality, and f) standing up for what is right.

Something that stood out to me that I absolutely loved was how, when the MMC was silent during the conversation with his friends/family about them not trusting the MFC fully, the MFC didn't get angry and whiny, and develop helpless thinking like "why isn't he standing up for me?" and blah blah blah (like the MFC in the current popular wolf book, which I loathed...). Instead, she believed in HIM and why he was silent, betting on the fact that he probably already tried to convince them and his current silence was 1) strategic and 2) giving her an opportunity to stand up for and defend herself, him not always speaking on her behalf and giving her space for her voice 💪🏻. YESSSSSS This MFC was already full of "what ifs" in their relationship, rightfully so; therefore, to see her trust him and his silence was beautiful 😘

This leads into what a strong couple the MCs are. They really balanced each other, as well as challenged each other to grow. The MMC was so thoughtful about what the MFC would want/need, communicating with her, and being thoughtful about how his past could haunt her. He always checked in and was considerate of her feelings. The MFC was also incredibly kind and thoughtful, always considering how her actions would impact others. They were both understanding, patient, and had shared values.

Also, of note: Overall, the word abandoned was used correctly and maturely, for a bit 🙌 (see my review on The Knowing Witch for context). Specifically, the MMC references his mother abandoning him. Again, this is an appropriate use, because the mother (one with more power and resources) left the child (the more vulnerable person). However, there was one thought by the MMC about how he had "abandoned" the MFC back in the day. Again, NO HE DIDNT.

The supportive characters in this book are strong and awesome. Turner is such a sweet side character. I hope he finds his HEA. Both MCs had family that were hesitant, yet genuine and cared. They had to challenge themselves to support the MCs, really showing up. They were excellent additions to the story.

The ending was sweet and beautiful, as well as set up the next book to hit the ground running. I would not say it was a cliffhanger. However, the details were clear on what the future book would include, which I am excited about(such as who the MMC‘s mom is, what happens with Cole)! The author does such an excellent job ending one book to then pick up strong in the next book.

Why not five stars?
One trope I despise is a break up that is dramatic, not based in strong rationale, and adds NOTHING to the overall story. Well, unfortunately, that happens this book. I could tell the author was really trying to sell the rationale, as evidenced by how much internal dialogue was dedicated to why she had to break up with him and stay broken up. Let's be clear, I was NOT buying the rationale. The MFC is significantly harmed and she feared death, totally get why she wanted to get the hell out of the Underworld (pun intended). She uses this to justify why she and the MMC could never be together.

- The MFC makes the decision to end their relationship without having an open dialogue with the MMC about this. 1) this was super hypocritical because the MMC previously made the same decision on their behalf and the MFC was mad and felt "betrayed." Here, she made the decision and just told him, no open conversation. 2) THEN the MFC is all passive aggressive, secretly wishing he would fight for them. NO THANK YOU! Don't break up with someone and then secretly wish they would fight for you and change your mind, toxic AF. Tell him how you feel and say what you need to say, quit with the teenager games. I was particularly irked by this since she was more thoughtful and mature throughout this whole book.

- I was not sold on the break-up because they could have been together and I was unsure of why they were both so convinced that they could not be. They love each other, why can't they be together while they still navigate the world? They can separate for some time while he goes to the Underworld and she navigates the Covens, all while being together. Having a long-distance relationship and not seeing each other for some time sucks, but for how much they said "you are mine" and the author dedicated time to convincing the readers the MCs would never love anyone else, why couldn't they just stay in a relationship while physically separating for some time? Again, because no one could talk about their relationship, this was never an option discussed.

Or, why couldn’t they stay together and spend the little time they had left together, and then end it when the spell was broke and they had to separate to do their own things? Why did they have to break up, travel all awkwardly, and then only realize they could be together? Although they had not said “I love you,” they knew they had strong feelings. Why not spend those last days together making memories, especially if it was going to end? The rationale of making it easier by breaking up now doesn’t make any sense since they were traveling for over a week together and pretending they didn’t love each other was much worse. The approach taken in this book felt silly, teenager like, and lacked the maturity I know these characters had/have.

The two approaches I mentioned could have created so much more tension, emotion, and intrigue than the approach taken. This is especially true because nothing came out of the break up, there was no point to it other to add some teenager drama of “I can’t make eye contact” and “I love him but we will never be.” 🙄

- Thirdly, because she made this decision and he just went along with it, 30% of the book is about the MCs pouting about the breakup. This is why I do not like the break up trope, it can stall the plot and the constant internal dialogue about why they have to stay broken up is overdone and boring. I will say though, at least the author moved the plot along during this pouting phase.

And lastly, this was not a five star read because of the pregnancy ick. Now, I don't mind the pregnancy trope, women get pregnant all the time, makes sense it is included in books. I actually love it at times, it can add a lot to the story. Yet, what gave me the ick is that the MFC was going to let the MMC return to the Underworld without ever knowing he was going to be a father. DISGUSTING! I get that women hide their pregnancy from a male because the male is abusive or harmful, but that is NOT the case here. Further, isn't the WHOLE series about how people in power held information from others and the negative impact of that on the people. People were never given a choice. The MFC was literally fighting for the rights of knowledge; yet, here she was ready to hide incredibly important information from the MMC and not allow him to make an informed choice. She decided for him on what was best 🤮 The sentence that I drew this conclusion from was, "Just hours ago, she was prepared to say goodbye to him forever, and deal with their child alone."

I lost some respect for the MFC because of this second book. She was such a powerful MFC, really challenging herself to grow and do better for the world. But to even consider hiding a pregnancy from a deserving partner, in addition to the passive-aggressive approach to the break up, was yuck to me. I still love this MFC and look forward to reading more about her in the last book.

The way I love Melissa’s writing! She keeps you on your MF toes the entire time and throws in little twists that have you like “wait… excuse me… what?!?!”

THE END OF THIS BOOK. You think the story is all wrapped up then BAM hit with a big one that completely changes the story (this is after another big twist mid book!)

And THENNNN I really do think I’m done and she throws in a little sweet surprise the very last chapter 🥲

The end of this book had me reeling and now that I’ve thought about it… I have some crazy theories that I’m curious about AND IF these are even remotely true… omg well done MM 👏🏼

I cannot wait for book three and to see how this wraps up!!

Back to the beginning though—

I loved that we picked up right where we left off in book one. We jumped quickly into the plot and got to explore Ty’s home turf and it was fun to experience this side of the story.

My favorite animal is Ty in the bedroom (or come what may) 🤤 the way he worships his queen but is also a dom is just 🔥

Why I took a star off:

— as much as I love Ty, sometimes he reminds me of a frat boy and I can’t get past these moments because they give me the ick and I can’t explain beyond that 😂

— there was a lot of internal emotional turmoil in each chapter that I just wasn’t in the mood for. I wanted to use that space to move the story along and I felt like I was just stuck inside their heads too much and found myself skimming those paragraphs.

Even with these two points I will still be diving into book three and eagerly awaiting its release 😍

This book, much like it's predecessor, was simply a fun and easy read. If I had to summarize it in one word: "efficient" - but in a good way!

We pick up right where we left off, and executed the main goal from the previous book to it's full conclusion, with limited frustrations or interruptions. And while there was a surprise "twist" at the end (that I'm not really sure I'm a fan of or not... yet?), there was no penultimate cliff-hanger; everything was tied up in a neat little bow, we are ready to head into the next book after being left with a "happy ending" & a promise of new challenges ahead. For some reason, that in and of itself felt refreshing. I'm eager to read the next book, but I'm not going to be obsessing and stuck in a rage-induced "need-to-know" fog until then. I'll be over here, patiently waiting.

Even if it was a touch cliche, I loved the relationship between Ty & Ena. They are so damn hot, heavy & even sickeningly sweet. Stick a fork in me, I don't care. The spice definitely delivered this book, and you didn't have to wait too long for it. I'm usually a slow burn girl, but this still hit the spot for me.

I'm excited to learn more about Omnis, and how this ties into Ty's mother. It was fun to get to know the Daemons & how they live. I'm eager to see how things unfold with the Daemons & Witches now that balance between Gaia & Iblis is restored... and the repercussions this will bring about for Ty and his dynamic with his Uncles.

Until then, this book left me on a perfectly content note. So far, a lovely trilogy!

Thank you so much for the ARC!
I absolutely love the Omnis series—TKW was incredible, and I could not put it down and this one did not disappoint. This installment picks up right where the TKW ended, and it was so fun seeing Ena in the underworld and getting that dual POV from her and Ty. I loved watching their relationship grow (and 🌶️🌶️🌶️) as well as the development of the side characters. The magic system continues to be amazing and totally unique. I really enjoyed how the story wrapped up with a sense of resolution while still leaving the door wide open for Book 3. I cannot wait to see where their journey goes next.


Small SPOILER below


My only small critique is Ena’s brief “I need to end this” moment. After the entire beginning where she was so gung-ho and determined to follow Ty wherever their relationship led, the sudden shift felt out of character. The quick breakup and just-as-quick reconciliation also didn’t quite match how committed both of them had been to sticking together no matter what, and the pacing around that section felt a bit rushed compared to the rest of the story.

Overall, I truly loved this book and can’t wait to dive into Book 3!

We pick up right where The Knowing Witch left off! Ty and Ena definitely level the spice up in this book 🥵, I absolutely loved seeing them rekindle their relationship after nine years apart. Their chemistry is still strong, and very fun to read.

The journey into the Underworld was really cool. I loved exploring this new 'realm' it felt fresh and very different from the witches and mortals, especially in terms of hierarchy, politics, and daily life. Seeing how daemon society operates added a lot of depth.

One of my favorite aspects was learning that not all daemons are evil Iblis followers like their King. Some of them feel the same calling to worship Gaia as the witches, which was fascinating. It was also fun seeing a more personal side of the daemons, family life, humor, and how they let loose definitely made them feel more real.

There were a few plot twists I wasn’t a huge fan of, but nothing that ruined the story for me. Overall, I’m very excited to see where the series goes in book three, and I already have some fun theories brewing!

I received this ARC from booksirens and am voluntarily doing this review! 4.5 ⭐️

A great continuation of Ena and Ty’s Journey
The Unknown Demon, Omnis book 2, by MM Parks is everything I hoped for and more. As a continuation of Ena and Ty’s story, it absolutely shines—deepening their relationship, raising the stakes, and pulling me even further into their world. Parks has a gift for balancing character growth with steady ascension in plot twists, and this book proves it on every page.

Ena and Ty’s dynamic is stronger, sharper, and more emotional than ever. I’m completely hooked, and I honestly cannot wait for Book 3 to see where their relationship goes next and how the unfolding new plot plays out.
The tension, the chemistry, the danger—it's all expertly woven together.

If you haven’t read The Knowing Witch ( Book 1) yet, do yourself a favor and pick it up immediately so you can dive straight into this incredible continuation of their journey. The Unknown Demon is an absolute must-read for fans of magical intrigue, romance, and immersive storytelling. I’m already counting the days until the next installment!

4.5 ⭐️ Obsessed! This was a great continuation from the Knowing Witch (book 1)! I liked that we jumped right back in where we left off and I thought the story and plot line was perfectly paced and engaging!

I also noticed that I enjoyed M.M. Parks writing even more with this second installment. Everything flowed so smoothly. I questioned a few minor things, but overall the book was great!

‼️ SPOILERS BELOW‼️

This book also brought a lot more spice 🌶️ and it was NICE 😏🙌🏽 I really LOVE Ena and Ty! Their relationship/character development was well done. I was giddy when they got married at the end of it this book!

I'm not a huge fan of the pregnancy trope, but I feel like it was done right. It sets up an interesting plot for the next book since Mel's visions aren't exactly clear...

Anyhow, I loved this 2nd book and I can't wait for the next!

That was an emotional ride!

Dark and twisty. More secrets. More truths. So many mysteries being uncovered.

Ena and Ty are in the Underworld, trying to figure out how to fix their world. While also learning how to be together, trust, love, and just be.

Ty is super busy and important, and that sometimes gets in the way, and Ena has to pretend to be something she isn’t.

The emotional trials they go thru, the realizations they have, and the action and adventure packed into all the spaces in between made this a page turner!!

We get a few extra characters. Lara is my fave addition. A few of them I’m super hoping we get to see their end in the next book. And Ty has a hellbound?! Like come on. Adorable.

This was a great second installment. Can’t wait to see what happens next!

The Unknown Daemon is an addictive, high-stakes sequel that completely levels up the Omnis Series. Following Ena and Ty into the Underworld added a fascinating, darker layer to the world-building, where the "evil" daemons Ena was taught to fear are revealed in complex, morally gray shades. The dual POV is a total win—being in Ty’s head was perfection, especially as he balances his chaotic loyalty with the intense, slow-burn tension building between him and Ena. I especially loved how M.M. Parks handled the "witch slave" undercover trope; Ena remains fierce, clever, and powerful throughout. With standout side characters like the grumpy Steig and my new favorite Lara, this book kept me hooked until its satisfying, (ALMOST) cliffhanger-free conclusion. I’m already desperate for book three!

Quick Hits:
The Vibe: Darker, spicier, and impossible to put down.
The Romance: Elite tension, dual POV, and phenomenal emotional growth.
The World: Immersive Underworld politics and a brilliant subversion of tropes.
The MVP: Lara (new favorite!) and the return of the grumpy treasure, Steig.
The Ending: A smooth, confident handoff to the next installment.

Book two of the Omnis series finds Ena and Ty in the Underworld with Ena posing as Ty's Witch Slave to fool the daemons around them. While this book is definitely much darker, and sadder, than the first book, it does avoid any of the worst tropes I feared when Ena was named a slave and placed in a collar with the worst of the Daemon king's men leering at her lustfully. And while the series isn't exactly wrapped up by the end of the book, it also isn't the painful cliffhanger I was dreading when I saw I there was only 70 pages left! Instead the author leaves it with a nice clean segue into the next book so we know where we stand and where we are heading next. Whew.

“You are so fucking stunning when you take what you want from me.”

Okay I thought I loved The Knowing Witch, but this book??? I absolutely ate it up and left no crumbs. Now I’m gonna get the elephant out of the room, there is a trope in this book that some of y’all MIGHT not like, but it’s listed in the author’s note- so check there first.

There was some back and forth in this book that made me want to throw my kindle across the room, but y’all don’t give up cause the story just gets better and better!

This was a fantastic sequel and a great continuation of Ena and Ty’s story! I was so excited to be heading to the Underworld, and it did not disappoint.

Ena is still learning and growing so much in this book. I love how genuinely curious she is and how much she genuinely wants to help the daemons.

The inner workings and politics of the Underworld were super intriguing to me, and I enjoyed getting to see Ty acting in his role there. I also loved getting to see more of Turner and Steig.

This book was darker and spicier than The Knowing Witch, and I was so here for it. 👀🌶️

The plot continues to deepen and develop, and there was great character development as well. I know with how this book ended that there will be more opportunities for Ena and Ty to grow together and in their relationship in Book 3.

I love that both books haven’t ended on huge cliffhangers. The overall storyline from Book 2 wraps up nicely without too many loose ends, and it definitely gives you a good idea of where we’re heading next. And I’m beyond excited to see what happens next in Book 3 and learn more about the Omnis!

Thank you so much to M.M. Parks for the gifted copy of this one! 😈✨

I was so lucky to receive an eARC of this book and finished it in less than 12 hours…it was that good! There was wonderful development in the relationship between the main characters that felt real and mature. Seeing these two finally get to express their feelings and actually spend time together was so satisfying. We also meet and learn more about important side characters. Overall, there was good balance and pacing between plot and romance. Can’t wait to see where book 3 goes…and the spice was spicing! 🌶️🌶️🌶️

After reading the first book, The Knowing Witch, I couldn’t wait to read the continuation and as soon as I got this ARC for the second book, The Unknown Daemon, I had to read it asap!

I can tell you, it did not disappoint!
I just adore Ena’s and Ty’s story sooooo much!
This was another 5 star read (I would give more of possible!).

We get to know more about the magic and the secrets from long ago, through and amazing plot development, while also being easy to read bringing new facts and characters. I loved the characters’ development we got and the new additions as well.

We continue to get great romance, with a few more hardships and yearning as well as a ramp up on the spice levels as Ena poses as Ty’s “witch-slave” and does not disappoint...

As with the first book, you can feel the dedication, the detailed attention and the immense love that M. M. Parks poured into her art!

And of course, I cannot wait for book three!...

Go pick these books up immediately!

I feel very lucky to have been chosen to receive an advance review copy for free, I’m very thankful to the author M. M. Parks, and I am happily leaving this review voluntarily.

I was incredibly keen to get back into this world and see where Ena and Ty were going in their journey to the underworld and it certainly did not disappoint. The continuation of Ena and Ty’s journey felt really seamless. I loved seeing Ena in Ty’s world and how their connection and respect for each other continued to grow stronger. I really enjoyed seeing Ena in Ty’s world and getting to know more of Ty’s friends. The found family dynamic was so good and I found myself just wanting to hang with them more!

I’ve loved all the magical elements throughout both books. The underlying system of the different gods has me very intrigued to see where it is all going to end and/or come together between the witches and daemons.

This was definitely a little darker and spicier than the first one but done so beautifully. I can’t wait to see what in store for Ena and Ty in book 3.

Thank you so much M.M. Parks for this eARC. I am loving this series and being a part of the journey 💙✨

The first book is I ever DNFed? Yup.

It took me 20 days to get 30%, I started and finished an entirely different book in those 20 days. This was a huge let down after enjoying the first book quite a bit.

The writing was meh. The chemistry was lacking. They were talking like 19 year olds from 2012 who are super awkward with each other. Which, to be fair, maybe they are 20 but it still the vibes weren’t vibing.

Good, but not great. It took a long time to hook me (I didn’t really feel invested until around 65%) but I get that the slow build was necessary to fully set up the situation in the Underworld. The ending was solid and definitely left me with questions. I did love the main characters and the side characters and will be reaching for the third book when it comes out!
