This book was everything! I originally picked up the first book in this duology last year when I was trying to fill the void left behind by Kpop Demon Hunters. I loved Darker By Four so much that I was counting down the days until the second book released.

Thank you to the author, publisher and NetGalley for an early copy of this book!

Let me start by saying that this had a very satisfying conclusion. My heart felt so full and even with a couple of things remaining a mystery I feel hopeful and so happy with where it all landed. The first book in this duology was about the magic and the monsters, but the second book was about the romance.

These characters are the type you feel deeply connected to. You root for them from the very beginning. And the relationships, both friendship and otherwise, are so beautiful 🥹 Rui and Zizi have my entire heart. Their lore is rooted in heartbreak yet holds so much hope and light. I could literally melt over how much I love them and their story. Another relationship that I could read a whole separate book about (I’m look at you June CL Tan) is Yuki and Yiran. Ahhh I loved how uncertain, slightly awkward yet wholesome their blossoming romance was and how they just understood one another on such a deep level.

I truly cannot say enough good things about this duology. It’s steeped in heavy folklore, high stakes, spirit magic, found family vibes with a romance that’ll sweep you off your feet. Please please PLEASE pick up this series and this book. I promise you won’t regret it.

The final part of this duology left me feeling a little cold. I really liked the first book and enjoyed this one for the same reasons, such as the world, the magic system and the relationships between the characters. However, I think many things remain unexplained, such as what happened to the kidnapped exorcists and what Rui's father was doing throughout the story. I was waiting for something to happen with him. I also felt that the evolution of Rui's feelings towards Zizi regressed in this book because of the plot. I really liked how she gradually realised that it was more than just friendship, so I was disappointed that it ended so quickly just because, in my opinion.
Nevertheless, I enjoyed the book and the author's writing style.

I like to thank Edelweiss and the publisher for allowing me to read / finish out the duology.

A lot of the feelings I had about characters (Four/Zizi) ended up being right. I rather liked his backstory and his reasons for doing what he did.

Unfortunately, this second book / conclusion felt muddled, too much going on and the fluidity was lost. The narrative and the looming threat of the blight and the creatures were explained but it felt so cheapened.

I can't point my finger on it all, but I think my issues come with the blight and the Four/Zizi story not really mixing together well and that both of them could be different books / different stories with adequate / proper time spent to link the two together the way the author wanted.

The other issue I have is that due to this, the world building suffers outside of the blight / supernatural aspect of it. I couldn't paint you a picture of the world because everything seemed to have a bland, grey background in my head as I pictured it. The only thing that had some sort of detail was the underworld (but not by much, that was pretty bleak too).

For a first book I enjoyed so heavily, to put this at a 3 was rather upsetting. Glad it was concluded but I wish it gave me more feeling when finished.

I’m really glad to see how much the lore expanded in this installment. We get a deeper look into the underworld, and I loved seeing how Four’s power—and his role as the Death God—fully comes into play. It adds a lot more weight to the story and the stakes.

I’m always a sucker for past lives and reincarnation, and I think this book handled that aspect really well. Watching how Rui, Zizi, and Yiran’s lives were intertwined across different lifetimes—and how their past choices continue to shape their present—was one of my favorite parts of the story.

And the romance… oh my god. I love a good forbidden romance, and June CL Tan really said let me hurt you emotionally with Zizi and Rui. Their love story was so intense and tragic in a way that just hits.

I also have to mention how cleverly the author plays with Chinese words and numbers—especially in the title and chapter titles. It’s such a thoughtful detail, and I always appreciate when cultural elements are woven into the story like that.

That said, I did find some of the dialogue a bit jarring at times. I understand that Zizi/Four is technically a young adult, but he’s also an immortal Death God… so some of the phrases he used felt a little too juvenile and didn’t quite match who he is.

The twist, though? Actually insane. I genuinely did not see it coming, but I really liked the direction the story took and how everything came full circle in the end—especially in how it impacted all three main characters.

Overall, I really enjoyed this book. I will say I personally preferred the first one a bit more, but this was still a satisfying continuation and a solid conclusion. Not perfect, but definitely good enough for me.

Thank you to the publisher and Netgalley for approving me to read this book, I’m rating it 4.25 stars.

I actually missed these characters and this world, I find the dynamics so easy to enjoy and the multi POV is exactly what I look for in a fantasy read.

In book 2 we kick off with things quite out of sorts with the realms, the hybrids and the characters themselves. Rui is dealing with her loss and grief like a champ if I do say so myself, she does become a little focused on the weird events happening to people so her grief seems minimised by her goals. There are new characters that raise some questions and truths in this story and try to lead certain characters on darker paths. I love that we get more interaction in the underworld so we expand on that realm and it’s rules, it has not survived unscathed by the events of book 1.

Now, my fav part of this book is Rui and four/Zizzi like my heart breaks for all that they’ve gone through and I’m a sucker for love that drives its characters. I will miss them not being on my page as the ending to book 2 seemed to conclude the story rather perfectly for me, but I wouldn’t say no to a spin off or novela, maybe a 10th king redemption arc who knows.

Thank you netgalley and hodder& stoughton for letting me read this book early!

After reading and LOVING Darker By Four last year I was so excited to pick up this sequel.

However, it did take me a while to get settled back into this world. For the first two thirds of the book it felt like I was reading something completely different and I just couldn’t find my groove with it. It made sense for the story, I just found myself missing the style of the first book.

Then something happened and the last third was exactly what I needed this book to be. Action packed, exciting and with all the characters engaging with each other and working together.

I think this duology is super unique and interesting and I’d recommend reading this series if you’re into:
✨Chinese underworld mythology
✨Urban fantasy
✨Friendships and love
✨Queer rep
✨Family dynamics

Thank you to HarperCollins Children's Books for the ARC!

Brighter Than Nine kicks off shortly after the eventful end of Darker by Four. Zizi and Rui are realms apart, facing their own individual challenges while trying to get back to each other. Yiran is navigating complex family dynamics along his feelings for Yuki. Ash is trying to keep his fellow exorcists alive and protect society from the increased threat of Hybrids.

This book is filled with action, suspense, and a side of romance. There is solid world-building and compelling character development. The additional POV of Zizi and Ash really round-out the storytelling. The queer representation is also lovely, I appreciate how normalized it is in this world. The plot wraps up nicely while leaving some things open for interpretation, which I liked. Overall this is a great duology and I look forward to reading more books by June C.L. Tan!

Thank you to NetGalley and the publisher for this arc. ♡

One of my favorite mythological concepts is the red string of fate that binds lovers for lifetimes. I also particularly enjoy when immortals get punished with either mortality or some form of servitude or imprisonment. I eat it up alwayyyyyys. June CL Tan created a perfect lush world of mortals and immortals that I thoroughly enjoyed. My adoration for Rui and Zizi increased in book 2, I LOVE them so much! All in all this was, to me, a near perfect conclusion to this duology. I spent much of this book theorizing different possibilities, and managed to guess so much which to me is a testament to how well the bread crumbs were laid throughout both books. (Although, a prior knowledge of Chinese mythology may have also played a hand.)
The side characters and their arcs were also engaging and at no point did I find myself bored of other POVs. Did I still want to slap Yiran? Yes, but only in the beginning. Even in the last book I understood why he acted the way he did but this book went more into depth with his story and relationships and omg??? UGH, I was so sad for him.

As for the ENDING????? WHAT DO YOU MEAN? THATS IT? YOU’RE JOKING??????

Now what? There was a moment at the very and that made me think there is a possibility of at least one spin-off.

3.5 my biggest pet peeve is when a sequel to a book that worked because it had a very lovable gang coming together has them all split up and ignoring what made the first book work. Like come onnnnn. However, this was still very entertaining and fast paced, with the same fun character and felt even more like a very entertaining anime playing out. I think the ending was a bit rushed (I was getting to a point where I was questioning if this was gonna be a trilogy or not), but very nice all in all.

Thank you so much to NetGalley and the publisher for an eARC! This was one of my extremely anticipated releases this year, and it was an overall satisfying conclusion to the duology despite falling a bit short of expectations.

I wish this would've been a trilogy, because I feel like there was a lot of telling over showing done to tie up all the plot threads. I feel like these could've been fleshed out fully with more time, and I would have enjoyed going a bit deeper into some of the mythology. I also missed our trio's interactions together, since they're separated for about the first half of the book.

The plot was definitely slower in the first half, but then quickly picked up and towards the last 10-20% it felt like we were at breakneck speed getting to the conclusion. I still enjoyed the world and characters, and really liked the short chapters (~10 pages). Some of the plot twists were a bit predictable, but I was still surprised by others. Overall, a solid conclusion if a bit rushed.

For the review in English, please scroll down.

Dopo il cliffhanger “illegale” con cui si chiude il primo volume, mi aspettavo che Brighter Than Nine partisse con tutt’altra energia. Invece il romanzo parte lento, forse troppo, e rimane tale per buona parte della prima metà. Dopo due anni di attesa, avrei sinceramente apprezzato un breve recap del libro precedente: mi sono sentita piuttosto disconnessa dai personaggi e dagli eventi, soprattutto all'inizio, nonostante riconosca che si tratti di un sequel solido.

Il punto di forza restano comunque i personaggi, anche se in modo sbilanciato. Zizi (Four) è senza dubbio quello con l’arco narrativo più interessante e sfaccettato, e l’aggiunta dei suoi POV è stata una delle scelte migliori del libro. Il suo percorso, seppur a tratti un po’ convoluto, è quello che regge maggiormente il peso emotivo della storia. Anche Rui mi è piaciuta molto come protagonista: coerente, determinata e profondamente legata a ciò in cui crede. Al contrario, Yiran è il personaggio che mi è piaciuto di meno in questo volume. L’ho trovato immaturo e troppo spesso irritante, e il suo sviluppo appare meno curato rispetto agli altri, nonostante il potenziale ci fosse.

Il worldbuilding, pur affascinante sulla carta, soprattutto per quanto riguarda l’oltretomba, il divino e le gerarchie di potere, rimane sottosviluppato anche in questo ultimo volume. Molti aspetti vengono solo accennati e non realmente spiegati o approfonditi.

Dal punto di vista del ritmo, il romanzo soffre di un forte squilibrio: come dicevo sopra, all’inizio la narrazione procede con estrema lentezza, poi a un certo punto accelera bi botto, con eventi che si susseguono in modo sempre più serrato. Questo crea tensione, sì, ma anche una sensazione di voler finire il prima possibile, con alcune risoluzioni che si concludono troppo velocemente. Il finale chiude la dilogia in modo soddisfacente, anche se non memorabile.

In conclusione, Brighter Than Nine è una buon finale per una dilogia YA che mescola mitologia cinese, atomsfere manga e romance, con personaggi interessanti e una scrittura solida. Tuttavia, da questo volume finale mi aspettavo qualcosa in più, soprattutto in termini di approfondimento del worldbuilding.

Thank you, Netgalley and Hodder and Stoughton for approving me with an eARC of this book in exchange for an honest opinion.

After the rather “illegal” cliffhanger at the end of book one, I expected Brighter Than Nine to open with a completely different kind of energy. Instead, the novel starts slowly — perhaps too slowly — and remains that way for much of the first half. After a two-year wait, I would have genuinely appreciated a short recap of the previous book: I felt quite disconnected from the characters and the events at the beginning, even though I do recognize this as a solid sequel.
The characters remain the main strength of the story, albeit unevenly so. Zizi (Four) is, without a doubt, the most compelling and layered character, and the addition of his POV chapters was one of the best choices of this book. His arc, while occasionally a bit convoluted, carries most of the emotional weight of the narrative. I also really liked Rui as a protagonist: consistent, determined, and deeply committed to what she believes in. By contrast, Yiran was the character I struggled with the most in this volume. I found him immature and often irritating, and his development feels less polished than the others, despite his clear potential.

The worldbuilding, while fascinating on paper — especially when it comes to the underworld, the divine, and the power hierarchies — remains underdeveloped even in this final installment. Many elements are only hinted at and never fully explained or explored.

In terms of pacing, the novel suffers from a noticeable imbalance. As mentioned above, the beginning moves at a very slow pace, only for the story to suddenly accelerate, with events unfolding in rapid succession. While this does create tension, it also gives the impression that the book is rushing toward the finish line, with some resolutions wrapped up too quickly. The ending does close the duology in a satisfying, but not particularly memorable, way.

Overall, Brighter Than Nine is a solid conclusion to a YA duology that blends Chinese mythology, manga-inspired aesthetics, and romance, supported by engaging characters and competent writing. That said, I was hoping for more from this final volume, especially when it comes to the depth and exploration of the worldbuilding.

Thank you Netgalley and the publisher in exchange for an honest review!

A year ago, I gave Ms June a Gojo cat pin and let’s just say it works a little too well. (Not in the Gege Akutami ending way but the angsty way) I was looking forward to the sequel and it didn’t disappoint! (Also, I read the second half after watching Zootopia 2, and my sequel streak stays winning!)

There’s a huge improvement in the writing style, and it’s a lot more fluid in the second book. Before reading BTN, I was doing a reread of DBF and my rereading of DBF allowed me to notice the subtle changes. The writing is a lot sharper and tighter in the sequel, and it’s less reliant on generic phrases. The comedic timing was also paced better, and I laughed so much at some parts. Moreover, the references didn’t feel like they were trying to compensate for the lack of something. Instead, it just added texture to the story that you’re already on board with, which is why this book was such a fun read.

Moving on, I think what this book excels at is that it has a very logical flow, with each scene tying up smoothly to the next scene. I didn’t feel like the scenes were wasted or filled with too many fillers that are not relevant to the story, which is the case for a lot of books out there. There are very clear incidents in this book that explain the character’s motivations and thoughts, which allow the readers to see and understand why they acted out in a certain manner, which leads to another incident. I think this is why I managed to finish this book way quicker than I had expected because of how nice it flows. It’s also why I didn’t feel that certain plot devices were used purely for the sake of shock factor. (A lot of anime/mangas do this, and it makes me frustrated.)

With that being said, I do feel that the pacing could ease off a little for the last 20% of the novel. Some of the minor conflicts in this book for the side characters weren't really addressed near the end and were quickly glanced over. Some of the side characters that were more prominent in book 1 weren’t really addressed as well, which made the conclusion not as satisfying as it could have been. I think this is partly because this book was more focused on the POV characters, which ultimately came at the cost of the other side characters.

Nonetheless, I still had a great time with the plot and themes in this book. It somehow reminded me a lot of one of my favourite manga, Chainsaw Man. This book clearly took a more depressed tone, which I welcome with open arms. It’s also a lot darker than I expected since it wasn’t that dark in the first book, despite being called Darker by Four. (Everyone please laugh now.)

Anyways, what I’m trying to say is that I enjoyed how this book tried to capture that sense of despair while working for a social cause. We get to see this through Ash as he tries to deal with this continuous cycle of tedium. He’s already on the brink of collapse, but there’s just so much destruction everywhere that his efforts just seem miniscule in comparison (think healthcare workers during the pandemic). Moreover, his frustration and internal conflict with his work were what made him such a compelling character to read (I think his arc might be my favourite out of all of the characters). And I think his conflict with the public opinion and society’s lack of trust in people who are qualified enough to do their job was such a great discussion on the ethical conflicts surrounding institutional betrayal and the lack of transparency. Anyways, Ash needs therapy.

Furthermore, I enjoyed how this book portrayed yuanfen. I think a lot of books or media in general only mention how yuanfen can only be used in a romantic and positive setting, which is not the case at all. After all, yuanfen can also incur negative karmic debt, which leads to a negative relationship in the future. So, the ‘twist’ in this book got me smiling a little when I realised what Ms June was trying to pull off.

I’m not going to say much about the characters since it will get spoilery, but damn, everyone here actually needs therapy. Yiran was my second favourite character to read about, and his relationship with Yuki reminded me of Angel and Aki. (Sighs…if you know, you know.) Yiran’s internal conflict for acceptance and him going down the wrong path because he was lost was just so heartbreaking to me.
All in all, this was a solid sequel even though there were some issues here and there with the pacing. But I still had such a great time reading it, and I’m feeling extra biased and generous for Zizi and Rui because of the unintentional (or maybe intentional) sly fox and dumb rabbit reference. So, I’m giving this book an extra 0.25 star!

Anyways, I’m going to tell my younger cousins to read this book (aka a less unhinged and more PG version of CSM) so that I can make them read CSM when they are older.

After the ending of Darker by Four, I was really excited and intrigued to see where June CL Tan was going to take the story after that cliff-hanger. Now with the arrival of the sequel, I can't help but feel like it didn't quite live up fully to my expectations and it ended up being a bit more of a mixed bag.

So where did it go wrong? Well, Brighter than Nine was dragged down as a sequel with its pacing and was just trying to do too much both. It struggles to find its footing with most of the story feeling disjointed with sections of the book like the underworld and the mortal realm failing to blend together as seamlessly as it should. The Hell portions were far more engaging to read through while the mortal realm aspects were more of a drag. This is in large part due to Zizi being in the underworld so his storyline was far more gripping to me because of how compelling and charming he is as a character. I could read a whole separate book of just Zizi as a King of the underworld. That being said the book does infinitely get better by the third act with all the pieces starting to fall into place and the action scenes are ramped up.

There are two new points of views with Zizi and Ash, while I loved Zizi’s pov chapters, I don’t think in comparison Ash’s chapters really added anything and fragmented the story even further.

There are some aspects that worked really well, such as June CL Tan excelling at writing in a way that really makes me feel like I’m watching anime and it is such a love letter to anime in general. The action heavy scenes are where the book shines the most. The cast of characters still have great chemistry together and I really enjoyed the scenes where they all meet up again.

~ 𝒕𝒉𝒆 𝒓𝒐𝒎𝒂𝒏𝒄𝒆 ~
The past scenes of Four (Zizi) and Lei Ying (Rui) were captivating, but the story desperately needed a bit more of them falling in love in those past scenes. I would have loved to have more of that section as a lover of the reincarnation trope. The build-up of their relationship with their present selves, was heart-aching at times with the ever present feeling of them being destined to meet but not fated to be together, looming over them. The tragic aspect really made certain moments more endearing due to the depth and the lifetime of feelings between the two of them, plus the banter between the two of them was just as fun and playful as in Darker by Four.

Review: 4 stars

BT9 takes place just after the ramifications of DB4 where the story ends in somewhat of a cliffhanger. We finally get additional POVs from Zizi and Ash! I’m so excited to jump back into this duology and catch up with my favourite trio.

We started the novel where the trio left off: Zizi is trapped in Hell as he grapples with his past, Rui is recovered and trying to figure out how to get to Hell for Zizi’s help to destroy the talisman that the hybrids are using to turn humans into hybrids while Yiran is grappling his vague relationship with Yuki, and his complex family dynamics.

With the characters being at different pivotal points of their lives, we got to see multiple POVs in play as each story plot took place as multiple aspects throughout the novel with it coming together in the climax. It was great to see each of them getting their stories told.

Zizi and Rui spend almost half the book separated as they had to work through some of their current circumstances on their own as they finally reunited. This also means that their usual dynamic, banter and fun-ness was missing. It felt like their present relationship and romance took a back seat in this one but their past connection and history was explored and highlighted with some crazy reveals! I swear at some moments the author did push the limits of certain tropes that I wasn’t a fan of but it still worked out! The ending did tie everything into a neat bow but also leave it vague. Rui’s journey in hell was fun to read (not gonna lie but this one reads better than *coughsKatabasiscoughs*)

Poor Yiran, he went through a wringer through this book. He had to figure out his feelings with Yuki with the forbidden aspect tied in. On top of that, figuring out his complex family dynamics and some revelations came to light about his past, parental relationships and his lack of magic. His story was just sad and angsty but his character growth was phenomenal! I also love how it was revealed that he has a past history with Zizi and Rui explaining their connection as a trio together - it was so fun to see their banter when they reunited before the epic climax.

I find this book to be more introspective as the characters work through their character arc and development. Yiran has the strongest arc as he and his brother, Ash work through their complicated family entanglements and plot. Hence, the storyline did unfold slowly and it ramped up in the last 40% of the book as things started to fall into place and we get all those action scenes we are dying for!

June’s writing excels here and you can see influences of our beloved anime with some hints of JJK, FMA etc especially during the intense action scenes. She did a solid job wrapping up the story and the characters arc with a hint of K-drama present in the end with a slight open ending but I do wish we had a few more chapters to really flesh out the aftermath of that epic climax.

Overall, BT9 was a solid follow up to DB4 filled with our beloved trio with a satisfying conclusion to top it off!

“Love wasn’t possession. It wasn’t a caged bird never spreading its wings or never feeling the sun on its feathers. Love was the act of freeing the bird without the hope that it would return.”

After the events of Darker by Four, the Guild has named Rui a hero, but she still harbors their secrets about the existence of Hybrid Revenants. Yiran is once again powerless, and he’s pushing away everyone who cares about him. His hunger for power pulls him towards betrayal, where he discovers a dark family secret. On top of this, Zizi is trapped in the underworld as his body deteriorates and his memories as the Fourth King return. Rui would give anything to have him back, and Zizi would do anything to protect Rui. Connected by fate, the three must create a new destiny if they want to save the world.

In my review of Darker by Four, I said that it was “the perfect contemporary fantasy.” If the first book was the perfect contemporary fantasy, then Brighter Than Nine was the perfect sequel. Contemporary fantasy has always been a favorite genre of mine, and June C.L. Tan has effortlessly woven a world of magic into a normal, modern world. With Zizi in the underworld, Tan further explored the mythology of the ten underworld kingdoms, the Nothing, and reincarnation. Tan utilized the magic and mythology to dive deeper into Zizi’s, Rui’s, and Yiran’s characters, which I loved. Every new discovery had a clear purpose and elevated the story. While the first book was about the characters building relationships with each other, this book had them look inward. All three of them had to reconcile with their inner turmoil in order to save both themselves and the realms. I love when the answer to the problem lies in the character healing inner trauma that they’ve been holding onto, because I feel like it adds more emotion and personal connection to the story. More than anything though, I enjoyed how magical this book felt. The reincarnation and red string of fate elements were beautiful ways of showcasing how their lives are all intertwined, and, in the end, it was platonic, familial, and romantic love that meant the most. If you loved Darker by Four, or just love contemporary fantasy in general, Brighter Than Nine is a must-read.

We start the book of right where we ended off in DB4. The first half of the story is much more introspective - our characters are asking "Who am I?" and "Who are they to me?" and those are large overarching questions through the first half of the story. There a lot less action in this one, Rui only really gets into a couple fights, same with Yiran, so it's not as fast-paced as book one. There's a lot of self-discovery and a lot of thinking in the first part of this book.

Once we see some movement in the middle, a few big things happen plot-wise that start to push the book along. I found the twists equally as twisty as the first book, and the action sequences that follow big and chaotic and well written. Like I said though, they are farther and fewer between in this installment.

I did like delving into the characters' pasts and figuring out how fate has woven all their lives together through the past and present. I also really ended up liking Yiran and Yuki's mildly toxic friendship despite my initial misgivings. I found the characters and their heart to be a core part of why I love this series, and I'm glad we got to get deeper into their stories and their family history as well.

One thing I thought was off was the world building - the book felt like three distinct acts, and they don't speak to each other that well. I wish Zizi's story had been a bit more fleshed out (esp concerning some of his history) and there had been a bit more discussion around the implications of those past lives and how fate bound them all together. I also wanted a bit more detail on Yiran's side of things. Like what trouble was being stirred up while the exorcists were distracted? I feel like there were some holes in there that were never really addressed.

All that being said, I truly loved the end of the story, it really tied up the duology nicely, though I was left with a few questions. I think this was a really strong story, and I would love a novella or two to fill in some of my knowledge gaps, just saying. I think this series is a lot of fun though and really gives those C-Drama vibes that I think the author was going for. In the end, a solid finale!

TW: death, murder, blood, injury details, imprisonment, mutilation, gore; mentions death of parent

Plot: 4.5/5
Characters: 5/5
World Building: 3.5/5
Writing: 5/5
Pacing: 3.5/5
Overall: 4/5

I voluntarily read and reviewed an advanced copy of this book. All thoughts and opinions are my own. - Freya, arc & monthly book box pick reviewer (on Instagram https://www.instagram.com/athenafreya... )

Initial thoughts: Chinese underworld, immortals and exorcists, conspiracies, and fabulous queer representation, this duology means the world to me.

About the book:
Rui is back at the academy, praised as the hero and torn because she knows the truth: that the underworld AND hybrid revenants exist...

Zizi is in the underworld, chained in isolation as they try to bring Four back to the surface.

Yiran is magicless again and when he discovers the truth about his past and his family, the truth about himself, he will need to make decisions...

What I liked 🤩: ABSOLUTELY EVERYTHING! THIS IS MY HEART'S MASTERPIECE! Character development: heartbreakingly beautiful. Worldbuilding: endlessly cool. Prose: as compelling as ramyeon.

I really have no words. This book was everything! Yiran, sweet baby Yiran, grew so much in this book. He discovered himself and embraced himself with all his flaws and desires. Zizi also reunited with his true self, his misconceptions and his pain but also his family who love him. Rui was the bad@ss who kept the boys going, the consistent and loyal person they needed in their lives.

The plot had so many twists and turns, I just held onto my bed and kept hoping that it would work out for my three beloveds. I don't usually bond to more than one or two characters in one book, but this author has probably descended from the Celestial realm or something, because my love for Rui, Yiran, and Zizi knows no bounds. I would go to the underworld for them, too.

The worldbuilding was so rich and expansive. The author took what we loved in book 1 and put even more of it in this book. I feel like this author wrote this book for me and others like me: queer Asia enthusiasts.

I miss them already, and I will go cry now...

Overall: I sincerely hope we get a spin-off about Yiran or even someone else in this universe. Rui, Yiran, and Zizi own my heart and my soul, and I am heartbroken that this duology is now over.

Rui may be Zizi's everything, but these characters are my literary everything. Perfection, from the first word in the first book to the last word of this book.

SE info: There is Fairyloot edition.

I was only sold on the last book at the very end when we learned of the history between Zizi and Rui. The rest of the book I was impartial to, but that hook of soulmates got me.

This book gave us bit more lore and understanding of the underworld, which I enjoyed. But there was almost too much happening and some plot threads were mentioned and then seemingly dropped. I don’t know if it’s because they weren’t actually important or if they just got lost in the end. For example, is Zizi/Four’s origin important? Did it really matter? And how about Liyen’s dad? He’s described as special. I thought he was going to be more important. What about the kidnapped exorcists?

Yiran has a lot going on and we learn a lot of his backstory while Rui is kind of stumbling through her romance plot. Yiran is learning about hybrid revenants and Rui is trying to figure out how to stop them. Simultaneously Zizi is learning how the Blight is connected to all of this and so the plot just became a bit confusing and muddled at points. We have real humans committing crimes but that is separate from the supernatural blight but the blight is also connected to humanity. It’s just muddled.

The first 60% was slowly paced and our trio, Rui, Zizi, and Yiran were separated for most of it. Rui wants to save Zizi from the Underworld so he can save the mortal world. Their relationship was still sweet, to a point, and I still liked Zizi’s characterization. His story had the most emotional weight. Rui’s side to it really couldn’t compare. Rui couldn’t really show her supposed badassery (again). That’s a problem I had with the first book and again here Rui was just flat and she never got herself out of the trouble she was in. She was always rescued by someone (or something) else. And that’s stale. And again, her side of the romance fell flat and there were so many unanswered questions with her backstory. Where Zizi felt like he was in love with her, she just felt like it was a schoolyard crush. And even then she regressed. Sigh.

Anyways, the ending happens quickly. It one big action sequence and everything wraps up nicely with a bow on top. Satisfying enough ending to a duology, but the story itself is not very memorable.

The brilliant and marvelous June CL Tan returns with the stunning and long-awaited sequel to Darker by Four...

Rui is now a hero to the Exorcist Guild. She seemingly has her life back together.... destined to become a captain of the Exorcist Guild... but she harbors dark secrets and the knowledge of Hybrid Revenants...and that they are planning something big.

Zizi is now trapped in the Underworld, trapped in a deteriorating state where his mortal body is giving out, and yet he is getting more and more access to the one known as Four. The Fourth King of Hell... his memories... his old love for the girl that Rui once was... and realizing that he alone may hold the key that keeps the mortal world from crumbling...
But first, he must escape the Underworld... must escape his brethren and break the rules that were set for them.

Yiran no longer has the magic that he once possessed. He's returned to life as he once knew it, and back to a school among mortals. He watches from the shadows as his friends at Xingshan Academy learn to embrace their magic.. learn to fight those that would harm mortals like him. When a dark family secret comes to life... and his desire for power urges him to betray those he once called his friends.... he must decide who he is... and what he wants to stand for once and for all.

If I wasn't already nursing a book hangover, I most definitely am now. Fast-paced, full of interesting mythology and of course, the continuation of Rui's unlikely love story... the tale of the three bound together by the threads of fate...and yet full of the most unlikely twists and turns.... this is an absolute masterpiece of Chinese mythology, blended with elements of Shadowhunters...
