Ninety-one years ago, I stumbled upon a window to a strange new world. Beyond, there were blue skies and odd trees, and flowers like nothing I’d ever seen. Curiosity got the better of me, and life as I knew it changed forever.

Ljómur was the military’s best kept secret. Behind those walls, I was experimented on and studied, torn apart and put back together. Caged, collared, and stripped of any sense of identity I once had.

A lifelong prisoner.

Now I’m free, and my former hell has been destroyed. Every bar that once confined me lies in ruin, yet I still can’t escape my cage.

It’s been a month since we discovered what the military was trying to do, and since I swore to bring the group to the rifts. Ever since, I’ve been living in fear of the day they’ll call on me to fulfill that promise.

No one knows better than me what’s at stake, but most days, my mind is not my own. When I’m lost inside my thoughts, only one person is able to reach me. Reyes breaks through the clouds and pulls me from that dark place in a way the others can’t. He tells me I still have something to give, but I’m not so sure that’s true.

I’m just a broken thing, after all, and those can’t always be fixed.


Author's note: Nyx is a First Person Dual POV MM Monster Romance series with explicit content intended for readers 18+. It is the second 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 books277 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.

Oh Nyx, baby. You deserve the world.

Objectively this book was just as good as the previous ones it was just not the kind of romance that gets me really going. But Nyx’s story had to be told and I loved seeing him finally finding himself.


But FML am I excited for Xeni now!!!!

I would like to give a warm welcome to the newest member of my list of all time favourite books, so happy to have you here Nyx.

There are some books that even before you start them, you know they will be a new favourite book for you because of the set up for it and this was the case for me.

Do you want to read a book that makes you cry so much that you start questioning your grip on reality and if you will ever be emotionally stable again? Well, I have the perfect book for you, and it’s this one. There was a part where reading this book where I was crying so much I started shaking so much I was worried I was gonna have a panic attack. This book hurt so much, but it was also the most romantic and comforting tale I have read in months. This book just had so much hope and romantic feelings intertwined in between all of the hurt and it made for the best reading experience.

The characters in this book were just so well matched, I absolutely adored them together. There was Nyx, that had spent the last 90 years of his life being abused and experimented on and that was very closed off and depraved of human touch and very scared to open up to anyone thinking everyone secretly wanted to hurt him. And there was Reyes, that has isolated himself for years and doesn’t really know how to act around people. I adored seeing them realize how much they enjoyed each other company and I loved seeing all of their interactions, so much. They were both just so soft and gentle with each other and it was such a delight to read about.

I love a very atmostpheric story that focuses on hurt characters and them healing throughout the book and a having a really sweet and comfort focused romance that makes all of their aching parts hurt a little less every day. And this book just captured every elements for me, it was just such a lovely reading experience.

i don’t know if im about to cry or throw up. like i almost killed myself reading this. but in a positive way!!

first of all, let me tell you something: i basically didn’t breathe anymore after the 80% mark. i was so scared that my sweet little baby nyx would suffer again that i genuinely couldn’t get enough air in. (i also have bronchitis right now, but that’s not important)
and we all know that g can make us suffer like nobody else.
did she do it here? i don’t think so, however im still traumatized after elas, so i was expecting it either way. i still felt all the anxiety without a sane reason, which is honestly what i do every day.
g, my queen, let’s keep the anxiety to this level, please.

well, let’s talk about the book.
actually, no, we have something more important to talk about first.
why the fuck haven’t you read ronan yet?
no, i don’t care about a reply. go read ronan, then elas, then nyx, then come back here and thank me.
love you!!

now, onto the book.
this author outdoes herself every single fucking time. i already knew that i would’ve loved nyx with all my heart, that i would only cry knowing what he went through and how he overcame it. so, no surprises there.
i was ready to love nyx and endure reyes.
is this a safe space to say that (up until elas) i couldn’t stand him? yes? no?
well, i’m saying it anyway.
like, i couldn’t stand him so much that when g announced that he was the human mate, i texted my friend taylor to complain. (i’ve never claimed to be smart)
boyyyyyyy was i wrong.
a chapter in and reyes quite literally punched me in the face with his perfection.
sure, he might be a bit weird at times, but he’s a MAN. like, read this:

"I'll teach you the plants I know, and you can teach me their names in your language."
"I... teach you? My words?"
"Your words are important, too," I say softly as his eyes shimmer and move up towards the sky. "Why should you be the only one learning something new?"


however, if i had to write down all the times i got up and applauded him, i would transcribe the entire book.
that’s how wonderful he is.

i genuinely loved every single minute of nyx quiet healing and i can’t wait to read this again.

and, of course, i am so excited for the next book!!

i’ve read an arc and this is my honest review🧡

I really enjoyed the emotional journey that Nyx and Reyes go on in this story. They are both haunted by their past while dealing with their fears and hesitations about going forward with a one-in-a-lifetime connection. Overall, this story hit me in my feels. Nyx is one of the purest souls, and watching him slowly open up to Reyes and learn to believe and trust in his mate was so heartfelt and beautiful to see. I couldn't get enough of these two and look forward to the next entry.

** I reviewed a complimentary copy of this story.***

God I don’t even know where to start. I think I’ve highlighted a million things in this book, and all of them are so freaking sweet that my teeth hurt after reading this. Nyx needs to be wrapped in a triple layer of bubble wrap, and he needs to want for nothing. This man is an absolute angel and nothing bad needs to happen to him ever again.

To be honest, I didn’t know how to feel about Nyx and Reyes being mated before I started this book. I just wasn’t sure if they were a good fit. Past me doesn’t know shit about fuck. They are the very best pair ever. Reyes is the king of consent and respect and support and devotion and probably a hundred more things. He is the absolute best thing for Nyx, and I hate that I doubted it. I loved them both so very much.

This is 100% a slow burn, which is not usually my preferred trope. But, this story literally couldn’t have happened any other way. Nyx has gone through sooooo much. You think he would’ve just jumped in the sack with Reyes at first glance? Yeah, no. Reyes definitely knew he loved him at first sight, but he had to go slow. They had to build trust and friendship, even after their marks showed up. It was such a beautiful thing, though. Like the pacing was absolutely perfect. There’s so many emotionally intimate moments between the two that just make you tear up. And because of those moments, when they did get physically intimate, you’re full blown crying. They have the best relationship.

All the other moments with Nyx and the other characters are just as sweet. Like teaching him English, how to read, funny jokes, cooking vegetarian meals just for him, etc. Nyx has the support and love he deserves after so many years of pain.

The ending of this book is amazing. The author has set us up for the next one and revealed some awesome things, and I literally can’t wait. As much as I love all the characters, I am so invested in this story as a whole, and so excited to see what she does next.

arc review (out nov 13th)

I swear, G. Eilsel is going to destroy me one of these days. But first, can I marry your brain?

Once again, I’m amazed by how perfectly balanced the plot and romance are in this series. I loved every single moment of it, even though I spent the first 20% smiling, the next 50% crying, and the final 30% smiling again. Nyx and Reyes’ story is one of a kind—a beautiful story about unconditional love and pure devotion. And the found family vibes? Chef's kiss.

Nyx, my sweet Nyx—I’m so happy you found Reyes. These two adorable souls truly earned their happily ever after.

And now it seems G heard my prayers, because the next book will be , my most anticipated baby! I can’t wait! 💖

Mate’s Mark is definitely my highlight series of the year. 🌟

Never have I ever read about a couple that was so soft and gentle with each other 🥹
Unlike Ronan and Elas, the first two books in the series (which you gotta read first!), this book is a lot more chill in terms of plot. Instead, it’s super focused on the slow-burn, high-sweetness romance between Nyx and Reyes as they settle into their lives in their new home.

Nyx is seriously SO SWEET. Like, every character in this book would go to war for him, and I would do the same. He’s so lovable!!! Despite the terrible things he’s faced in his past, he’s such a gentle soul. And the way Reyes treats him like he’s the most precious being to ever grace the planet!!! Ugh I loved them. Sickeningly sweet! 😍 they had so many amazing moments of physical, emotional and spoken intimacy.

This book also does a great job establishing the characters from the previous book as side characters, which I really enjoyed. I’ve always been a big Roman fan, but this book made me love him even more!

Though this book didn’t progress the overarching plot much, it added some good setup, and definitely had me itching to find out what’s next!! This book also really further established the setting and characters, and endeared them to me even more. There were a lot of funny and “smiling at my kindle” moments in this book as well.

I really enjoyed this instalment in the series. This author puts so much effort into her books, and even does art for them!! So cool!

Definitely make sure to read the first two books in the series, and pick up Nyx on November 13!

Nyx & Reyes - ugh. I just want to squish them both. I knew I was going to love Nyx's story. I fell in love with him in Ronan and Cameron's story & couldn't wait to get to know the little nymph baby.

His story has a lot of heartbreak and pain but also is very tender and sweet. Somehow G. Eilsel was able to toe the line of pain. She gave just enough and then soothed the ache with the tender sweetness that is Reyes. I was emotionally edged in the best way.

Something I didn't expect though to come out of all of this was my undying love for Elas. I thought for sure Nyx was going to take the crown and while I still love him and would go to war for him. There is something so endearing about the blue giant that I cannot get over. There's a moment he shares with Nyx that is so devastatingly beautiful I sobbed for him, for them all, for everything they have all gone through and will continue to go through. And while I didn't expect this to turn into a wee bit of a love letter to Elas, here we are.

There is something so special about this series. I will continue to keep with me. Each story just brings a bit of healing I didn't know I needed.

Xeni is up next and the little snippets of his backstory that were shared in the end, let's just say I will be waiting on tenterhooks for his story.

A MM monster romance which is heartbreaking with its hurts but heals with sweetness & comfort 🥺. It has size difference, slowburn, found family, & love that blooms with lightness.
I had been so freaking excited for Nyx & Reyes' book! N's been through too much, my baby 😭, he deserves to be cherished by his fierce mate R 🥰. I loved them! I was waiting to read my #ARC at the perfect time but it became a balm to my soul when I felt sick 🥺❤️, I savored this. Adored seeing everyone again! This book is more characters' focused, has HFN for our couple & Plot cliffhanger.

💚Nyx is a Drüinae, prisoner #1. He's been captured most his life, so long he doesn't know how to be free now. N makes me ache, he's so sweet & cute but feels broken 🥺. I loved seeing him blossom. His sass, pouts & bravery are amazing!
🌼Reyes is a Human. R thinks of himself as a coward, but is a survivor. R's snarky, stabby (😂), short-tempered but absolutely gentle, kind & so patient with N. I loved his teasing, devotion to N & N's choices. R's the gardener of our crew 😁.

It was obvious how R was such a goner for N 🤭, N liked R too. They love nature but are hermits & awkward around eachother 😅. It took coaxing & time, but I loved them slowly open up & be happy together 🥰.

We got edged with them finding out they're fated mates, but what a dramatic reveal 😉. Hurt, past & flashbacks 😭... but not much relationship angst. They're sweet, & heck ya, eventually hot 🥵 too (gotta love monster anatomy lol 😳). I was wishing nothing bad happens, N's been through too much, R too 😢.

I loved R's protectiveness for N & when it's N's moment to shine, omg lit ✨. There were moments that had me tense, & that climax omfg 😈. Btw, I like revenge. We've got new peeps added, & I'm so curious about Xeni's story & the nature of mate marks! G, I agree with your choices & I'm excited what's next. I was glad we got to see Elas (& Ron) healing too ☺️.

Oh, how much I missed this series 🥹

I was so ready to learn more about our special Nyx, who endured so much. He possibly is the strongest soul in this little group of humans/monsters, although we have yet to learn from the other couples as well.

Reyes is the perfect match for him, he is such a patient gentleman, always putting Nyx's needs and well-being first ❤️‍🩹

Since this is an dystopian world, where monsters control most of the world and every day is a fight for survival, you can expect lots of action. The mates that are found in this stories definitely add romance and lots of spicy-time, so you have the whole package 😍

I cannot wait for the next book ✨️

"People too often think the best way to infiltrate a broken mind is with brute force. They want to bore inside with forced conversations and constant noise, but sometimes, you need the silence to heal."

I loved Nyx - I loved it so, so much. I don't think there could possibly have been a better third instalment in the Mate's Mark series, I really don't. It physically hurt in the best possible way and I desperately want more. I could read a thousand stories set in this little camp and never be tired of them.

I’ve been preparing myself for Nyx’s story ever since we first met the scared, sweet Nymph in Ronan. You'd think I'd have been ready for the heartbreaking, gut-wrenching tale G wove for him, but I wasn't. I wanted so badly to protect him - to wrap him up and feed him snacks, while simultaneously curb-stomping everyone who had ever wronged him.

"I w-want, and I don't know how to have. I have never had anything."

Nyx was more than just a dystopian monster romance, and I absolutely loved that. It dealt with some really, really heavy topics like captivity and extreme confinement, depression and suicidal ideation, anxiety, PTSD, torture and slavery, just to name a few. Each topic was handled with sensitivity and every bit of dialogue surrounding those themes and thoughts was written with the intention of showing survivors that they are safe now, and that what they think and feel and need is being heard.

Reyes said it best when he said "a giant piece of me is dying to bundle him up and keep him safe… wrap him up in blankets, feed him snacks, and just spoil him until he forgets he wanted to do this. But his choices matter more than mine, and I’ll never steal those."
I appreciated the hell out of Reyes for the space he gave Nyx to start healing, while still showing him unconditional love every moment of every day. He gave him the room to start trusting again without babying him or making him feel like he owed anyone a fully healed version of himself. They each found a safe home in the other and it showed.
Even before they knew they were Fated Mates their softness towards each other, juxtaposed with their fierce protectiveness of their relationship and of each others lives was beautiful. Both Reyes and Nyx deserved someone who would stand up for them and have their back no matter what, and the mark on their skin only heightened how much they cared for each other.

"I'll teach you the plants I know, and you can teach me their names in your language."
"I... teach you? My words?"
"Your words are important, too," I say softly as his eyes shimmer and move up towards the sky. "Why should you be the only one learning something new?"


The truly beautiful thing about the Mate's Mark series, and especially Nyx, is that the pain and the suffering that the characters experience, while still there and still raw, doesn't at all eclipse the happiness they've managed to find with their mates. One of the quotes that I really, really loved was "Nyx could be angry for a lifetime, and it would still be righteous.". Reyes' simple acceptance of the time it was going to take Nyx to even begin to heal was so lovely to read. The romance never negates the pain - it's not treated as a cure-all. The feelings of love and pain co-exist beautifully to give us a truly well-rounded, well-written characters.

And speaking of well-rounded: the balance between the plot, the romance, and the spice was fantastic. There wasn't a single moment when I felt like the story dragged or had too much/too little of one thing or another.
I loved how well the little domestic moments and the slice-of-dystopian-life scenes meshed with the anxiety-inducing action scenes. I was holding my breath for the last third of the book because I knew Eisel was going to put my sweet little monster and his human through the absolute wringer. And was I right to fret? Yes and no. She gave us some absolutely heart-wrenching moments, but then kissed our boo-boo's better and popped a little Katsurrel coloured band-aid over them to last us until she does it again with Xeni.

Another thing I really I loved was that no one was forgotten as the story progressed. Our main men from Ronan and Elas weren't relegated to useless side characters simply because their story had been told, they were still an integral part to the overarching plot. But they also didn't detract from the important roles Nyx and Reyes play in advancing the story. I'm so nervous and excited to see where their plot goes. But I'm going to absolutely riot of any of these characters (and I do mean ANY) end up in emotional or physical pain again. You hear me, Eisel? Consider all of them a no-touchy zone from now on. And y'know what? Include Xeni in that. If he gets hurt in his book I'm going to... well, I'm definitely going to cry.

I feel like I've just waffled on and not articulated my feeling very well, but I can say with absolute certainty that there was nothing about this story I didn't like. The characters, the plot, the magic - it was all perfect.
Y'know how sometimes you're desperate to see what happens next in a book series and you build it up so much in your head that when you finally read it it's not as good as you were expecting? That didn't happen here. At all. Eisel has outdone herself, she really has. I can't wait to read Xeni's book. I'm nervous as hell for it, but that's what I get for falling in love with side characters.

5/5 stars. I feel the same way about this book that Nyx feels about strawberries.

Have a parting quote:

"I stretch both arms towards him. Reaching for him... always reaching for him, and he always reaches back."

I was fortunate to receive an advance copy of Nyx. I’ve been so anxious to see how his and Reyes’ story unfolded. I knew it would be heartbreaking finding out all the details of Nyx’s past - 91 years in captivity 😢 I’ve never been so happy for a slow, gentle, and patient love story. Reyes was exactly who Nyx needed (love how Ronan eventually admitted that lol). With the ending, I’m definitely excited to see what happens next with Xeni and his mate! Also, I’ve got my eye on Aryn… 👀 I think it’s great they are extending their “family” and sharing resources with others in need. Hopefully the new additions will prove to be a good move.

Love this series so much! 💕

i have never hated reading the word “epilogue” as much as i hated it here

ever since ronan pulled this “hopeless, caged hummingbird who has lost his will to live” from his cage i’ve been head over heels in love with nyx and his gentle soul

his book, much like nyx’s life is aching, painful, and heart breaking. this makes it all the more healing when reyes shows up to love him. because this isn’t JUST an epic love story. these two are fated mates in the deepest and truest sense of the word. these are two people that the entire cosmos conspired to unite. and through every glance, kiss, gentle touch, and whispered word between these two you can literally *feel* their love spiraling out through time and space, past galaxies, and out into infinity

out of all the fated mates reyes and nyx feel like they’ve been together since the universe popped into being

they are exactly what the other needs. reyes give nyx the safety and unconditional love our little green man he’s been cruelly deprived of ever since he stepped through the rift, enchanted by the sight of a beautiful patch of eye-riss. and nyx gives reyes a reason to be courageous and brave, after a lifetime of thinking himself a coward. they fill each others blank spaces, and heal each others deepest wounds

i can’t say enough good stuff about this book. it’s just as engaging as ronan and elas’s story were. which is no surprise—eilsel writes beautifully. it’s just a fact 🤷🏻‍♀️ she practically apologizes for the lower level of spice in this book as compared to her others. but it felt *right* to not have them hop into bed in the first quarter of the book. so, yeah, the spice level is lower, but the *heat* of the spice that IS there… scorching 😮‍💨

so, i was sad to see it all end. i could read a whole spin off of this book alone. give me a duology… a trilogy… fuck, give me 14 books with special edition covers, bonus chapters, character art, and decorative slipcovers, and i will buy—and love—every. single. one.

read this. please. start with ronan, and then elas, because these aren’t standalones, but every step of the journey is worth it. eilsel is walking us toward an ending that is sure to be explosive, awe inspiring, and exquisitely satisfying. and i, for one, intend to take her hand and follow wherever she leads me

1️⃣ **Overall Rating:** ⭐️⭐️⭐️⭐️⭐️

2️⃣ **Overview/Synopsis:**: Book three of the Mates Mark series. We get to learn Nyx story.

3️⃣ **Favorite Character:**: Reyes. He’s just a giant teddy bear and I love what he does for Nyx

4️⃣ **Most Memorable Scene:**: I absolutely want to make out the way they do in a stream in the forest.

5️⃣ **Favorite Quote or Line:**: “Don’t stop. Never stop. I want you… want you. Please,” he pleads in a whisper, and my heart fills so full of him that I think it might shatter inside my chest. “I want you to have me… want you to love me.”

6️⃣ **Overall Review Summary:**: Man this story is packed with the best kind of Hurt/Comfort. Like stab you in the heart but not let you bleed out before wrapping you in a really warm fleece blanket.

Sweet baby Nyx. What they did to you, I have no words. We get to live his story while he shares it we the Reyes and we get to see how Reyes wants to just take the pain away, but on his terms. He always gives him the choice, which was so important to be portrayed.

The survivors guilt is so potent on Reyes but it helps him relate and make a connection work Nyx, it definitely helps with their beginning, the understanding.

This is in my opinion low spice, but it’s perfect for them. There’s a lot to unpack and I appreciate that Eilsel didn’t rush it out just make it smut for smut sake.

The world building is still top tier. I love the creatures she’s made and the lore and magic. It’s all just so encompassing of an experience

Needles to say I’m diving right into Xeni and continuing this amazing series

Guys, we have a new favorite read of the year! 🥹💛
I honestly can’t put into words how much I love Nyx and Reyes. These two are just perfect for each other — two souls who found one another despite (or maybe because of) all the pain they’ve been through.

Nyx… my heart. He’s such a broken soul, far too good for this world. The meaning of the dandelion fits him so beautifully — strong, resilient, yet still full of hope. I wanted to jump into the book and just hold him so many times because he deserves all the love in the world. 💛

And then there’s Reyes — another walking green flag! I adore his patience, his understanding, and the way he gives Nyx the space to heal. He’s exactly the anchor Nyx needed, and together they help each other find peace again.

And stones and flowers as a love language?? My heart couldn’t handle it. This book was emotional, healing, and absolutely beautiful. I swear, I was a puddle of feelings by the end.

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

4,25* mucho mejor que los otros. Las mayores críticas en este libro es que tiene menos spicy y eso mejora muchísimo el libro, siento que los otros fuerza escenas y en este se toma su tiempo con los personajes (POR FIN). Sigue con sus toques de humor y avanza en la trama principal que une todos los libros.

Lo que me descoloca de esta autora son las escenas violentas supergráficas, siempre concentrado en el 80% final, en este están espolvoreados por todo el libro y son sobretodo son los recuerdos y hechos vividos por el protagonista, cosa que obviamente te esperas desde que encuentran a Nyx en el primer libro. Me parece excesivo su sufrimiento, es una razón que no tiene más puntuación por mi parte, es algo habitual de la autora.

Ahora a esperar el 4° porque parece ser que me gusta sufrir, pero es que necesito saber más de Xeni. Los personajes de esta saga 🤍.

G, you are the whole a$$ for writing this book! I laughed, I cried, I scrumpt a lot and my heart ached. The brokenest of boys made for each other. I honestly didn't know where this book was going to go with Nyx' past and what we know about his life before being saved but I was along for the ride.

I loved it and absolutely cannot wait for the next book. I especially loved seeing Nyx find his voice and his sass. He'll soon be giving Cameron a run for his money.

My favorite book in the Mates Mark series so far!!! I was lucky enough to be on the ARC team for this book, and the story blew me away.

Nyx and Reyes were such an adorable wholesome couple. Reyes worships the ground Nyx walks on, and they heal each other in such a profound way.

Awesome found family story, lots of hurt/comfort moments, and many firsts for our sweet Nyx.

I can’t wait to see where the rest of this series is going!

Nyx has been my favorite character from the moment he showed up. I love him so much and I am so glad he gets a wonderful mate who is soft and sweet with him. I love the strength he has to forgive Xeni because I also love him. The overall plot for thjs series has been super interesting. This book progressed it but not by all that much because this one had to focus on healing Nyx and I think that was perfect. I loved this book so much.

Nyx is the third book in the Mate's Mark series. This series is best read in order because of an overarching storyline. This is the story of Nyx and Reyes. This book was hard to put down once I started. Nyx was such an amazing character and watching he and Reyes was the chef's kiss. This story had me crying but also gave me hope. This whole series will tear you up but also put you back together even better than you were. I can't wait for the next book in the series. I would definitely recommend this book and series as 5 star reads.

From book one the 1st time I read about Nyx I knew his story was going to break my heart. Never will a character be able able to hold the same place in our hearts as our sweet and beautiful Nyx has stolen. This book made me laugh. It made me cry to the point of having to set it down and wipe my eyes. Reyes, I am so happy he was given a piece of this story. His kindness, gentleness, and love for Nyx shined through every page, and theirs was a match made perfect.

I love how this entire world keeps building more and new characters come, but past characters are always still there not to be forgotten.

One of my most anticipated books of the year.
Did not disappoint, and I'm so excited to read Xeni's story next, but until then, may we all be granted a wish upon the dandelions.

The slow burn nearly killed me and the love between Nyx and Reyes was so beautifully written. So sweet and so perfect, just like them. I really enjoyed getting to know the other characters as well and the new ones were a good addition as well, I cannot wait to see what's next. And that ending....ahhh! How does this series just keep getting better??

Sweet Nyx! What a hard life you have lived. This story absolutely broke my heart!!

It’s so wonderful to see how tender and sweet Reyes is with Nyx. How fiercely he protects him at all times. And to see Nyx learn to trust Reyes was beautiful!

This series is fantastic! I love the found family and how we get to see more of them in each book.

If you haven’t started the series do yourself a favor and pick it up right away.

I’ve been on the edge of my seat for Nyx’s story since his first appearance in Ronan. I couldn’t wait to get a book from his perspective and this was everything I wanted it to be. The soft, slow burn of felt perfect for this story and for this point in the series. These two are so sweet, I just want to squish them. I was very grateful that no real drama happened in this, Nyx (and all of us) definitely deserved a breather.

The hurt/comfort in this was everything. We were already given an inkling in the last book of Reyes’ feelings for Nyx but the obstacles in their way seemed insurmountable. Watching their relationship slowly unfold as Nyx grew in his confidence was completely wonderful. I honestly love these two to death.

I’d also like to add that this book was unexpectedly funny considering some of the subject matter that it tackles. Reyes’ inner monologue and Nyx’s language mishaps were hilarious.

Another great entry to the series and I can’t wait for the next one.

⭐ 4.5/5

Oh how I loved sweet baby NYX!! How cute is he!! I’ve been looking at this series for a while and once I finally made time for Ronan I binged all three books in just as many days. This entire series is great but at this time Nyx is definitely my favorite story and my favorite character. I really enjoyed Nyx and Reyes’s gentle bond. They got to know each other through gardening, snacks and learning each other’s language and I loved all the healing that took place during this time. Their relationship dynamic was sweet and Nyx coming into his own was great to see! I loved his sass and his implementation of new words was hilarious. I really appreciated how patient and understanding Reyes was and how he made it a point to let Nyx make his own choices and regain his autonomy. Loved this book and I’m excited to learn more about Xeni! 💚🖤💚
