It's been almost a century since the veil fell and monsters invaded the world. We didn't give the humans an opportunity to retaliate as we charged in and took over, and I was at the head of the front lines with my sword in hand. A perfect soldier, fighting the battles that ultimately put my people in charge of this planet. Half of humanity was slaughtered, and in the decades since the invasion, things have only gotten worse. Tensions between the rebel humans and monsters grew as the climate changed, and temperatures rose as resources dwindled. The sun scorched away plants and trees, leaving behind a husk of a planet where everyone fights for survival.

The Fates were furious at our violence, and now we're trapped inside the hell we created.

We've all heard tale of the Mate's Mark, and how we're destined to find our fated mate. One human, one monster - foretold to be the cure to this cursed world and repair the damage that has been done. What was once the cause of curiosity and intrigue has turned into nothing more than a mockery. Decades have passed, and not a single pair of fated mates had been found.

Until now.

Until me.

Until the night I pull off my armor and find the mark staring back.




Author's note: Ronan is a First Person Dual POV MM Monster Romance series with explicit content intended for readers 18+. It is the first in a series that will have an overarching storyline carrying between books. While this series ends with a guaranteed HEA, individual books end on more of a HFN basis. The feature couple's story will be resolved, though there will be some unanswered questions and mild cliffhangers that lead into the next in the series.

About the author

G. Eilsel

19 books258 followers
G. Eilsel started writing under this pen name in early 2024, publishing works in two genres she loves: eccentric novellas and MM romance.

Her writing puts a focus on sarcasm, snarky humor, sometimes horrible puns, and steamy scenes that'll make your momma blush. Expect heavy spice, in any sort of variety you're looking for-sweet, emotional, depraved, or downright questionable.

Some of her books are one-handed reads with minimal plot, others are more intricate stories that weave themselves through her brain and demand to be put on paper. Angsty and emotional, light and giggle-inducing, and everything in between can be found between the covers of her books.

She doesn't take herself too seriously, throwing pieces of her humor and quirky personality in her writing. If she can't live up to her title of a One-Handed author, then maybe she can at least make you smile.

loved Lily Mayne’s Soul Eater, so when I stumbled across this book, I thought, “Nice—Soul Eater but in a different font.” The premise had me genuinely intrigued: post-apocalyptic world, monsters roaming free, potential for dark romance and gritty survival. Sign me up, right?

Well… turns out I should’ve just re-read Soul Eater.

Let’s start with the worldbuilding— Apparently, the monsters crossed over into the human world more than 100 years ago, and humanity is basically toast. Civilization? Gone. Society? Collapsed. But somehow our main character talks like he has Wi-Fi and TikTok. Lines like “I slow clap for some added pizzazz,” or “someone give this guy a job in PR,” or calling someone “Emo boy”? Really? Who's handing out marketing degrees and pop culture references in this monster-ravaged wasteland?

The inconsistencies were wild. I was constantly yanked out of the story by modern slang that had no business surviving the apocalypse. Unless there’s an underground tik tok still working somewhere?

And then there’s Cameron. Oh, Cameron. At first, I thought his snark was a coping mechanism—he's stuck in a nightmare, sure, let him be dramatic. But it never stops. He's snarky in every. single. sentence. It went from mildly amusing to “please shut up” at lightning speed.

As for his love interest, Ronan the monster... he was just there. A growly, vaguely threatening wallpaper. Their chemistry was nonexistent, their dynamic flat, and honestly, I kept hoping a better monster would show up and steal the spotlight (and Cameron’s vocal cords).

Overall, I was disappointed. I wanted to love this. I should’ve loved this. But what I got was a snark overload in a world that made zero sense. Do yourself a favor—if you're craving a mm monster romance, stick with Lily Mayne. At least her apocalypse has believable vibes.

To put it similar to martina, this was what I wished “Soul Eater” had been for me.

This was an epic dystopian tale that will hopefully also span over a lot of books. The author set up a lot to explore here.

The veil fell and monsters invaded the world. After slaughtering half of humanity and taking control the fates are pissed by their violence so they basically curse them. Now they’re destined to find our fated mate. One human, one monster - foretold to be the cure to this cursed world and repair the damage that has been done.

The first pair we get to see is a kind-hearted but intimidating beast of a monster with the rank of an Officer and a feisty little human, a lone wanderer who get picked up by the military together with a whole lot of rebels by mistake.

And so they journey begins. Always on the run in search of safety for them both.

Defined muscles bunch and bulge beneath, glistening with sweat. And damn. I mean… damn. He looks as though he was carved straight from marble and impure thoughts.

Bright blue eyes are framed behind a pair of glasses, sharp as a razor and angry as a hornet.


I watch his shoulders rise and fall, sleeping peacefully on his side of the barrier. Making as much racket as I can, I sit up, but the bastard sleeps on, oblivious. Mighty warrior, my ass.



I loved how their relationship progressed which was not as quick as I expected given they were fated mates. The tension was delicious but it took especially Cameron a while to get over his hangups and start to trust Ronan. But Ronan really fought tooth and nail to make Cam believe and trust him.


“What about the times I say all those ugly things I don’t mean? When the glue holding me together fails, and these broken pieces fall apart all over again? It feels like I’m always hurting you, Ro… what happens when I do it again? When I push you away?” “Then I’ll just have to hold on a little tighter those days.”


*swoon



I already can’t wait to dive into the next book. This was awesome. Great world building, I never felt lost, and a decently fast paced plot that was captivating and made it hard to put this one down.

ARC REVIEW

Dystopian romance with a side of 'wft is going on', a snarky human paired with a serious protective monster, and a dog.
I thoroughly enjoyed this story. It's fated mates, which I love, and, for a dystopian book, it was quite low angst. There are a few quite tense moments, but it all turns out for the best.
Cameron is a snarky sassy human who has been alone and fending for himself in a collapsed world controlled by monsters. Ronan is a high ranking monster soldier who discovers his mate amongst a few rebels that has just come to his base. Once they acknowledge what is happening with them, they escape the base and slowly develop true feelings. Their interactions are pure gold and their romance is so sweet.
They learn that there's something else going on with other fated mates, and the monsters and humans, which isn't solved in this book, but there's enough mystery to make me want to read the next books.
Oh, and self lubricating dongs are a plus in a dystopian world.
I really loved this romance. Can't wait for more!

Okay I wanted to adore this one, and there were some things I loved, but some things that I felt could have been improved upon.

I want to start by saying that this book is incredibly similar to Lily Mayne’s monstrous series. Now that’s not a bad thing, and Lily herself has posted about this book, so it’s not a case of plagiarism or anything (the two world are juuuust about different enough to avoid that) but I do think that it’s risky when writing something so similar… because as much as I enjoyed this, the whole time I was thinking ‘Lily did it better’.

The story follows human Cameron and monster Ronan. Cameron is caught up in a camp raid and is taken hostage. Whilst in captivity, he meets soldier Ronan, and they both realise upon meeting that glowing mate-marks are now showing on their skin. Desperate to save his mate and take him somewhere safe, Ronan breaks Cam out of prison and they begin the anxious journey across the wastelands, to a place where they can be together and safe.

Let’s talk about what I liked:
- The world-building; this was great. Overcrowded cities where humans live, military bases where the monsters rule (in this world the monsters have the upper hand), raider camps, swathes of wasteland. Super engaging!
- The action scenes were good and I felt drawn in; blood and guts galore!
- The sex. I’m an absolute h0e for monster smut and this was pretty decent monster smut 😌
- The fated mates aspect was cool and interesting and I wanted to know more…


Stuff I struggled with:
- Unclear POV; a lot of the time I had literally no idea who was talking and I had to go back and check. Both of them have this sarky, flippant way of talking that just blurs after a while.
- Characterisation; Ronan especially bothered me, as his ‘monsterness’ often seemed forgotten about. When talking to his friend, he refers to himself as a man, but when talking to Cam, he says ‘I’m not a man’. Also he refers to himself as a monster, and also as having an inner monster… whilst Cameron tries to reassure him that he isn’t a monster? I just feel like the author sometimes forgot that Ronan was meant to be ‘other’ and he comes across as too human.
- Backstory; I wanted to know more about the magical(??) fated mates bond, but we barely got anything… I assume this is a plot line for a later book.

I also feel that any book, especially LGBTQ+, that is released in 2025 that has the unironic phrase ‘I almost cried and lost my man card’ deserves to lose at least half a star. Come on.

All in all a decent read but I ended up with a lot of questions that I would have liked answered (significance of mate marks, more info about magic(?!), more info about Ronan’s past, more info about why the worlds collided, more info about who the mysterious Fates are…) and whilst I realise many of these answers may come in later books, it’s left me feeling a bit lost. Who knows, maybe I’ll read this again after context from future books and absolutely love it? (Which happened to me with Soul Eater, so it can happen!)

Thanks to the author for providing me with an ARC of this book via booksirens 💕

This was, hands down, one of the best books I have read so far this year. I was laughing, I was swooning, I was fanning myself, all the things. I LOVED this book. This is one of those buy the paper back kind of books for me.

Now to the juice. So basically long ago the veil between the monster world and the human world was torn apart. The monsters stormed the human world and took it by force. It was a massacre. The fates were so angry with what the monsters had done that they closed the veil to where the monsters could not return to their home. They now are in control of the human world. In some sort of truce, the fates made it where every monster has a fated human mate, but the only way for them to find out is to touch them. Once a monster and a human touch (if they are fated mates), a glowing mark will appear where they touch. Such an interesting introduction!!! I was hooked from page one.

Our main characters here are Ronan (monster) and Cameron (human). Cameron gets accidentally kidnapped/arrested by the monsters with a bunch of other humans. It’s this whole thing, poor cameron. Anyway, after Ronan gets done putting all the humans into the cells, he notices that his palm is glowing. The mate mark. The issues here are this:

1. He is the first monster with this mark since the fates gave that decree. He does not know what to do about it.
2. He probably shouldn’t tell anyone (else) His bestie knows. But he doesn’t know how others would react.
3. He just put many people in cells. He doesn’t know which human is his mate, or where exactly he touched them.

So Ronan and his bestie go into the cells in search of a human with a glowing arm? neck? back? shoulder? It was such a funny moment. I loved it. Cameron is such a character.

Anyway Ronan and Cameron find each other. They realize what they are to each other. They realize what they mean to each other. And then Ronan kills a bunch of people and goes AWOL from the military and runs off into the sunset with his mate. The end.

Okay yeah I wish. It’s so wild. I felt like I had everything clenched until I got to the end of the book. But really the majority of the story is them getting to know each other while they’re hiding from the military monsters. Soooooo good.

The spice in this?? SPICYYYYY. So freaking good. We also have some “get your hands off my mate” moments. Also throw in some “touch him and die” moments. This author reached into my brain, saw all my book desires, and wrote it. I LOVE HER.

I am sooooooooo ready for the rest of the books in this series. The author left some mild cliffhangers, but it’ll make for an excellent series. This girl has a massive brain, and I can’t wait to see what she comes up with.

sharpen your pitchforks because i’m about to piss off every single one of you.

this is what soul eater pretends to be.

and by that i mean an amazing book, but also a good monster romance. compelling world building. great characters. wonderful love story. interesting over-arching plot. it also lacks the boredom to put you to sleep, which is something i personally enjoy.

i genuinely can’t wait for the next one

arc review

It's been a while since I truly enjoyed a book and when I tell you I totally devoured this story oh boy I'm not even joking... I'm completely obsessed with these characters now!!

This book follows Ronan (a giant, lovable monster with a heart of gold) and Cameron (adorable on the outside but armed with deadly sarcasm that could take you out in two seconds), as they navigate through their journey of being mates in the wastelands.

Their relationship development was truly captivating to read, it was my first book by the author, and it definitely didn’t disappoint. When I tell you it had the right amount of plot and the perfect amount of spice, I mean it.

I seriously can't wait for the next character's books, Elas and Nyx I see you!

I totally recommend this book for the fans of Lily Mayne and Mell R. Bright, trust me on this.

Rating: 4.5/5 🌟
Spice: 3/5 🌶️
Characters: Cameron and Ronan

Okay so I just love sweet vulnerable monsters with grumpy exteriors and a penchant for unaliving people.
Was this a little similar to Soul Eater? Yes, but also drastically different.
It felt a little longer than it needed to be and sort of dragged in a few spots. But overall, I thoroughly enjoyed this and can't wait to see where the rest of the series goes. I have a few characters I'm really hoping we get to see their romances.

“My world…my home… is nothing more than a memory, and we have no one to blame but ourseves.”

Tenía mis dudas porque pensaba que iba a ser una copia de otros libros que he leído. Justamente empezaba de esta forma y el argumento daba la sensación que iba por el mismo camino.”

Sin embargo, a pesar de que tiene su parecido en ciertas partes, hay que destacar que el libro está bastante bien escrito y la autora se lo ha currado. No sé si será su primera novela publicada, pero me quito el sombrero.

Por otro lado, si que no voy a negar que se me ha hecho un poco cuesta arriba porque sentía que no avanzaba la historia.

Seguramente lea el segundo libro.

3⭐️ This was okay. I liked some parts of it—mostly the first half as they work out their relationship. But ultimately, I was bored because not enough happens after the halfway mark.
They’re on the run together from monsters who want them dead for defecting but then they hole up in an abandoned house and just have sex for most of the rest of the book. I needed more action, danger, and plot. I needed more about the fated mates prophecy.
A lot just felt too cliche.
This might be fine for readers new to fantasy romance but if you’ve read a lot, nothing new here.

This was my first book of G Eilsel’s and I absolutely loved it. While it has the similar monster apocalypse that Lily Mayne Monstrous series has this one is drastically different. Cameron is so very insecure which can come across as childish and immature in the ways he handles his emotions but his sass and snarkiness more than make up for the few instances that he acted out. Ronan is possessive, protective, but so very very sweet. I really enjoyed the fated mates side of this story and I loved that (for me at least) I can’t say for sure where I know the overarching plot line is heading. This is definitely a top read of mine and I can’t wait to see where the rest of the story goes. Looking forward to Elsa’s storyline and also to hopefully get more information on poor Nyx.

OK, I have officially found the King of Snark. I sometimes say that a character is like a feral kitten - Cameron is like a feral kitten that you are tying to give a bath too. That man is FEISTY! That attitude made for a lot of fun banter though, and thank god that Ronan is super patient (mostly), because otherwise he would have bonked him over the head very early on. I really enjoyed the snark though, because its easy to see why he is the was he is, and I really felt the emotions behind it.

This was such a fun read. As we all know, because I say it every time, I love Post Apocalyptic / Dystopian romance. I love the adventure you get with these kind of stories, and then add fated mates and Monsters - yes please! I thought this was a great beginning to what I think is gonna be a fantastic series.

I really enjoyed this one.. post apocalyptic books are a guilty pleasure of mine and just recently got into MM romance thru Lily Mayne and this books is super similar to her Monstrous series.

Ronan is the monster in this book and the action takes place around 80 years after they invaded earth.
Cameron ( all i could think of was Cam from modern family 👀🤷🏻‍♀️) is the snarky human that turns out its his fated mate. There some prophecy around the mates mark that was thought to be fake but as Ronan found out its not.

There’s some tense moments, some funny ones, some major revelations and some steamy scenes all climaxing on a HFN.

Theres a few thing i didn’t liked tho, the vocabulary the monsters used was just modern slang with lots of modern references that have absolutely no place in a post apocalyptic wasteland 80/100 years after earth as we know it ended.
Cam got on my nerves lots , there’s cute banter and then there's just rudeness which Cam excelled at🙄.

Veeeery similar to Lily Mayne's series, like... too similar. Even if Mayne doesn't care, the concepts felt SO copypaste that it was like I'd already read this book. And since I didn't particularly love Mayne's take, it wasn't exactly a good thing for me, but some may enjoy. So here we also have bland, watered-down monsters that give me absolutely nothing I want from that trope. The writing (especially at the start) was so flowery it was difficult to get through a paragraph, and the author really dialed the snark/sass on Cameron up to 11, to the point where he was storming and stropping off at the drop of a fucking hat, including during an escape from prison where he had to be told multiple times to shut the fuck up. It was so unbelievably annoying and frankly I cannot believe this character genuinely would have survived on his own for so long given his mouth. The whole thing just fucking annoyed me.

I've read 2 or 3 different series so far that exist in the same sort of niche as Lily Mayne's Monstrous (Post-apocalyptic MM monster romance) and I think that this one is probably my favorite outside of Lily's.

Positives-
The quality of the writing itself was good.
There was clearly a lot of effort and planning put into the plot and worldbuilding.
The characters themselves had believable emotional arcs.
The romance and spicy scenes were great.
Good setup for future books.
Good action and tension.

Negatives-
The two POVs could be a little muddy here and there. I found myself having to double check who was the current POV and who was talking in dialogue because Cameron and Ronan had similar voices at times.

Overall, I think this was a 4.5 star book(rounded up) and I can't wait to read more in this series!!

The story:

🟣 Earth is a wasteland. Monsters rule. Humans either live under their control or scavenge to survive. Resources are scarce, the climate is a disaster, and tensions between humans and monsters are at an all-time high. My fave scenario for an apocalypse.

🟣 This story is incredibly well-written, with action, romance, and just the right amount of gorgeous world-building 👌, enough to set up the bigger picture without overwhelming you. Oh, and it even has a map... one of my ultimate weaknesses!
As for the story itself, it paints a vivid dystopian future where Earth is a dangerous, rebellion-fueled wasteland full of secrets… plus plenty of banter, bickering, and undeniable chemistry between the MCs. And the SC? So lovable that I just want to hug them all.

🟣 While this book gives Ronan and Cam an HEA ending, the overall storyline is HFN, as big questions remain unanswered, with a mild cliffhanger leading into the next book, and I can't wait to get my hands on it!

🟣 Cameron’s dynamic with Ronan is full of tension, banter, and that irresistible fated mates pull. Ronan is serious and disciplined, while Cam is sarcastic and stubborn. And Ronan’s care for Cameron? Absolutely precious. (Pretty mate, must protect… Tiny waist—must feed.)
🫠 Ronan doesn’t do soft… except when it comes to Cameron.

🟣 These two are absolute perfection... enemies to reluctant fated mates. The tension? Off the charts. The bickering? Hilarious. The spice? Chef’s kiss. 😘

🚙⛺️ P.S.: One of the many highlights I loved in this book was them being able to travel in a vehicle while searching for food, resources, and shelter. 👌



▪︎FAV QUOTES▪︎

■ Stubborn human can’t decide whether he wants affection or is annoyed by it.
“What are you doing?” he demands, and I laugh at the irritation in his voice. My prickly little porcupine, with his quills out and ready for a fight.


■ “Humans should come with warning labels and care instructions,” I mutter as I trail behind him.
“What was that?”
“Absolutely nothing.” I don’t miss the glare he throws at me before marching into the house.


👍I'm definitely going to read this again

If you’re into MM monster romance, fated mates, and a dystopian setting with action and spice, Ronan is a solid and enjoyable start to the series!

💯 I'm looking forward to reading the following books in this Series. I can’t wait!! 🙏

😉 Thanks for reading hope this helps you out!

Omg I can't say enough of how much I absolutely LOVED this book from page 1. It grabbed my attention and just hooked me. The story ,the spice, the love that grows between Cam and Ronan.
I have a habit of highlighting in pink in my kindle my favorite parts of a book, and basically, by the end, the entire book was practically pink 🩷

I swear when it comes to writing perfect banter G.Eilsel has it down to a science I found myself laughing often on the banter alone in the book and Ronan I've read a few monster/alien books and alot have been wrote where the character was very robotic but Ronan was definitely not, he was so full of personality and there was a few parts that I wanted to cry for poor Cam.

I'm beyond excited to read this series as it comes out. Elas story and Nix story I know I'm going to fall in love with just as much.

Ronan made my top 5 reads so far this year, and honestly, I do not see it dropping out of my top 5 this year.
I highly recommend reading this one. You will not be disappointed.

I really wanted to like RONAN and it actually started out pretty good; it's very similar in overall world idea to Lily Mayne's Monstrous series but I think this stands on it's own pretty well. I liked the addition of fated mates and I liked that Cameron wasn't scared to stand up for himself. However, that was his only redeeming quality because otherwise he was a snarky asshole and unbearable to read about. He never listened in life or death situations, he was constantly mean to Ronan (though Ronan supposedly liked it) and he completely blew up on Ronan for not giving up everything he knew for someone he just met 2 days ago...someone who made it clear he wasn't interested in having a fated mate by the way. Make it make sense.

!! I don't equate fiction stories to real life. It's a matter of personal taste and what you are willing or want to tolerate in the books you read. We all have different opinions and preferences when it comes to the kind of books we enjoy, so it's important to respect and remember that it's just a book!!

Loved this book. Reminds me of Soul Eater universe by Lily Mayne.

Ronan and Cameron had such fun banter, their relationship didn’t get boring once they got together it only got better.
The only thing I wish it would’ve been done differently if the build-up to their relationship and tension was stretched a bit. It feel like they gave into the bond way too easily and I would’ve loved some angst or tension.

Overall I’m def reading the next book.

This book is very reminiscent of “Soul Eater” by Lily Mayne but also distinctly different. I’d say the world is the most similar (I.e, dystopian military led world invaded by monsters) but the monster-human dynamic is a little different here with monsters and human military teaming up because the monster world is annihilated. There’s also a fated mates components and the characters have unique traits when compared to Mayne’s couples and characters.

Cameron is a nomad in the wrong place at the wrong time and ends up a prisoner of the military with Ronan being one of his guards basically. This book included fated mates which is not my favourite and I really didn’t like it here because it causes there to be no tension or build up. We know by the 20% mark they’re mates and despite some arguing they’re basically all in by the half way point. I did like the side characters and I can see the overarching plot for the series starting and I am curious.

The main reason I didn’t love this was Cameron and Ronan. They’re both sassy and sarcastic and bad communicators and the dialogue is so sappy between them. You could’ve erased the dystopian atmosphere and the dialogue would’ve held up just fine. I like August, Elas, Nyx and Reyes so I am excited for future books which I assume will feature all 4 and I hope the character and couple dynamics are better. The dialogue just lacked charm and wit and Cameron was insufferable and Ronan was predictable. Also the alien aspects of Ronan are extremely glossed over which seems like a missed opportunity. Cameron doesn’t even notice Ronan has 3 tails like what. But he is educated on Ronan’s knot bc of course he has one of those! Also this book is over 450 pages which is a -1 star on its own. The first 20% and last 10% were interesting but that middle portion could’ve been cut way in half.

Also, bring back real conflict in romantasy/scifi romance. Even in Lily Mayne’s series there is a compelling 3rd act conflict in every instalment that feels dramatic enough to spice up the book while keeping it relatively feel good. I’ve noticed that so many romantasies, straight and gay, have taken on a cozy element in an otherwise not cozy story and it’s boring. When Cam finds out Ronan was in the raid that killed his family he’s so unbothered to the point I don’t know why we included it in the first place. I can see more angst for Nyx’s story so I will patiently wait b/c I know Elas is the next story.

Soul Eater meets Soulmate Mark AU

Similar enough to Monstrous that it will appeal to Lily Mayne fans, different enough that it doesn’t feel like a copy. The world, its monsters, and the conflicts are all unique enough to draw you in. I love the flip of having the monsters be the organized military and the humans be the scrambling scattered beings.

Ronan and Cameron are definitely damaged people, and their relationship is flirtatiously barbed and extremely codependent. It works for them, though it wouldn’t be a relationship I’d enjoy. Cameron’s sass is a little heavy at times. But they fit together well and I wish them a lot of healing.

Excellent spice to their scenes. (Though I would suggest bonus scenes that utilize the tails more.)

I’m looking forward to the other stories. I have a feeling I might enjoy them more, since the other humans aren’t as bratty.

Spice: 3-4/5
Angst: 3/5

Ronan and Cameron just so freaking cute!!!! Cameron broke my heart with how he viewed himself, I just wanted to love on him so hard. Luckily he had Ronan there for that. This definitely started off strong for me, and kept the momentum for most of the book. I would say this book def focuses on world building and showing Ronan and Cameron's relationship build which kept my attention through and through.

Overall I did enjoy this book, and can't wait to read more of this series.

I am absolutely blown away right now, the writing of this book is incredible and impeccable! There is so much history that gets told throughout the story that infirms the readers about what happened to the world and how it came to be that way. The level of detail and backstory of everything is just fantastic and was done phenomenally!!

The characters themselves were terrific! There was so much angst between Ronan and in the beginning, rightfully so. Overtime though they learned more about each other and how to communicate better. Ronan has a gentle soul who was made to be a soldier, he cares deeply for those around him and he wishes no harm comes to those that are innocent. Cameron grew up in the world as it is now with seeing all monsters as the enemy, and he's used to people leaving him. Which is why he's extra weary of Ronan, but overtime Cameron stops flinging sharp worded barbs at Ronan and let's himself get to know the sweet monster with a heart of gold.

The aspect of Cameron and Ronan being fated mates is really unique, I've read a lot of books that feature the fated mates trope, but I have never seen it written like the way it is here before. And I love that! I love when authors can take something and make it their own, and that's exactly what happened here.

Now, while Cameron and Ronan are fantastic, and I love how their relationship is an excellent slow burner, I want to talk about the other characters that popped up. Those being Nyx, Elas, and of course, Boomerang. I thought that all of the side characters were amazing additions to the storyline, they were fantastic to the story and the characters themselves each had their own individual personalities. Something else I really enjoyed is how at the back of the book there are pictures with depictions and descriptions of each monster mentioned throughout the story. I loved that feature and thought it was such a cool way to provide additional information while still being creative and fun.

The mystery component that's within this story was intriguing, all the twists and turns just made me want to continue reading. And while the mysteriousness didn't get solved, there was more clues that were sprinkled throughout the story which has just made me eager for more books within this series.

I am absolutely looking forward to the next instalment and I hope you give this book, (and this series) a chance.

November 2025 Update:

Ronan released on audio and you know I preordered it as soon as I could. I am obsessed with Declan Winters and Zachary Zaba now. They were perfect voices for Ronan and Cameron. It was amazing hearing some of my favorite lines come to life. As soon as the audio finished, I was ready to restart it and listen again. Can't wait for the series to continue to come to audio!

ARC review for Ronan by G. Eilsel

Thanks to G. Eilsel for the ARC opportunity!

What to Expect: MM, monster/human, fated mates, forbidden romance, romantasy, grumpy/grumpy, allll the banter and snark, virgin MC, age gap (112/26), knotting

Trigger warning: G Eilsel is fantastic at including a comprehensive list of triggers and content warnings at the beginning of all her books. Definitely check it out before reading but, above all, know that the dog is okay.

Review: 5/5

Does G Eilsel have a fan club? Are there invitations extended...or how does that work? Whoever's in charge, know that I'm inviting myself in to the club because, once again, this book slaps so hard. I don't think it's possible for me to not just love one of her books. We clearly have the same sense of humor and the banter and snark alone suck me in every. damn. time. Anyways. Let's get to it.

Things I liked:
- All of it? Can I just say all of it and leave it at that? Seriously. I love Ronan. I LOVE Cameron. I just loved the whole thing. As usual, the banter and snark was just fantastic. While definitely (and obviously for good reason) more plot focused than the One Handed Holiday novellas, the spice still be spicin'.
- Guys, seriously, it's just SO good. This is a planned seven book series and she does a great job setting up this world. That being said, I didn't feel like it dragged in the world building like I understand a lot of fantasy books can do in book one of a series. The story flowed well and the action was well dispersed through the story to keep things interesting as you learn about the world and as Ronan and Cameron get to know one another. Fantasy is not *usually* my go-to but I cannot even begin to express how much I loved this.


Things I disliked or missed the mark:
- Nothing. Really. Not a thing. But, I will say, this is why I don't usually read fantasy. This is book one. OF SEVEN. I'm foaming a the mouth for the rest of the series. I want it all. And I want it now. I'm ready to make this series my whole personality for a while.

So, do I really need to say it again? I loved this book. You should too. I genuinely have the biggest book hangover right now and I'm already ready to reread this. Don't mind me while I just sit here and wait for book two (and three, and four...)

A dystopian MM Monster romance set on an invaded Earth with a Fated-mates prophecy that could change it all. It has All The Feels, laughs, "I love this" moments, lots of tears, spicy fun & packed with action! A great start to series, with a HFN for our couple & an overarching mystery.
I loved Cameron & Ronan so freaking much!! The world & it's characters are intriguing. I savored my #ARC!

💜Ronan is an Anunian who's given 90yrs to military. He's a grumpy, orderly warrior with multiple tails 😉. He's got guilts & regrets 🤧. Underneath, he's soft, patient, endearing & domestic 🤤. Loved his protectiveness!
👓Cameron is a human, been a wandering, survivalist for 6yrs since he lost his all at 20. His only companion is a sweet doggo (nothing happens to her!). His mouth's a weapon, snarky & sarcastic. I LOVE IT 😍! His insecurites & broken-ness run deep 😭. He's a "cute prickly porcupine" 🥺💕.

“I don’t want you to be easy, Cameron. Fight me, scream at me…you’ve got all that fire inside you. Don’t extinguish that for anyone.”

Both hardened by circumstances, so similar yet different. Kidnappings, Jail break, a glowing mark that changes their worlds forever. Is this a means to an end? Are there more? What the f is the military planning?!

R+C's romantic tension is delicious, hurt to care—the build up is nice & I just love 'em together! How they exchange barbs, lift eachother up, adorable idiots 😭💕. Sexually experienced & a virgin in a room, lala. Led to spicy hottt-ness 🥵, first times, praise & tail play 😍. Love me a vers couple!

The plot is fun, tho it's "surviving" then "home?", Nothing world-saving as of yet lol. Its just the start so I get it! The groundwork is laid tho. Some dark themes, angsty situations & bloody action 😈. That end reveal was a full-circle moment, SO POETIC 😍.

That epilogue, ugh, I'm so excited for book 2! Elas & August definitely got an adventure of their own eh? I'm so curious about Nyx too. & Reyes! We've got a crew, folks 🥳.

The moment I saw : "Every day, pieces of my home, my life, are chipped away by time’s insistent chisel.", I was 100% sure this's going to be one of these unforgettable, heart-piercing books that will leave a blazing trail behind in my memory and hold a special place amongst my favorite books. And I wasn't wrong. The author has done really outstanding work in creating and piecing together such a complex, vibrant, colorful world with so many races invading Earth after the Veil has fallen. Humanity as always is well represented in a convincing, rather realistic way in its complicated dichotomy.

Despite the difficulties, the challenges and the obstacles, people and monsters have found their new way of living on a planet, ravaged by neverending wars. The masterful descriptions are boosting the fast paced plot line and enhancing the emotional experience while the imagination walks page by page, meeting more and more intriguing details with each new chapter.

The moral dilemma who is actually the real monster in this dystopian, post apocalyptic world adds additional suspense element because after the initial invasion and the clash between the new species and the old ones who already leave on Earth, the whole picture have somehow dramatically changed.

The concept of fated mates and how their existence could turn the tides and unite invaders and survivors is implemented from the start and is the foundation on which the whole plot is built on. Ronan is one of these endearing kind of characters whose personality and temperament are simultaneously charming and infuriating and make the reading one better and very interesting experience. Coupled with all the sass and brass, one little human can contain /Cameron/ and the adventure quickly turns laugh-out-loud ridiculously sweet, spicy and addictive.

I can't imagine how it could get any better, but I have no doubts, the author has one/two more Aces, hidden to make the next book even more interesting.

I know this has been compared to Wyn.
However, I think they fall in their own areas.

I thoroughly enjoyed this book.
it felt like a story being told instead of it being completely focused on the relationship of the main character. Lot of side character action. LOVE NYX and BOOMERANG. I see Nyx got his own book, so I can't wait to read that.

I think the ending was a little abrupt.
The author was not playing about a HFN.

I do think that Ronan cared a little more in the relationship, and I'm not really a fan of uneven relationships.
Cameron gave very much brat. I never really got the meaning behind the glasses and not taking them off besides the obvious or why he felt/feels he is so broken. That felt pretty unanswered to me. He was very sarcastic and not really my favorite.

I'm glad they brought Elas back in the end. It felt weird that Ronans, essentially best friend, helped him with his mate. They dipped, and then it wasn't really talked about.

I'll definitely keep reading the series, but this didn't necessarily knock me off my feet, but it was good.

Fantastic start to a series

Cameron is so ballsy, brave, and ridiculous. He’s snarky and made me laugh so much. Ronan becomes a little snarky and sarcastic, but it mostly seemed like Cameron rubbing off on him. :-) These two have so much playful banter; they’re just a really fun couple. There isn’t a lot to laugh at in their world, so enjoying each other is so important. The world building and plot is phenomenal. I was engrossed from start to finish. It definitely ends on an HFN, which the reader knows going in. I can’t wait for the next books, especially knowing who one or maybe two of the next couples are. Also to learn more about what’s been going on, and the secret location and people taken there.
