“Logic bows at the throne of obsession.”

When Wren discovers a body and Castien in the tunnels on the same night, she’s certain she’ll never be able to trust him again. But that doesn’t mean she no longer needs him.

In order to discover the killer taking down their fellow students, Wren is forced to rely on Castien’s strategic mind and his knowledge of the Obsidian Order.

Wren wants nothing more than a cordial alliance, but Castien is intent on winning much more than her loyalty. He longs for her heart.

As they learn to trust each other again, the secret of Wren’s stolen journal looms over their fragile happiness like a storm cloud on the horizon.

Will they be able to withstand the tempestuous winds, or will they be ripped apart in the end?

Find out in Tides of Secrets, the epic conclusion of the Obsidian Academy Duet, a love story tinged with obsession and drenched in yearning.

Thank you Netgalley and Dreamscape Media for an ALC of Tides of Secrets by A.R. Conwell 

🌟4.5 🌟

Some sequels spend the entire book trying to recapture the magic of the first book.. we don't have that problem here.. Instead, it generously expands on it. Instead of simply going through the motions by raising the stakes, it leans deeper into the emotional consequences of everything that came before, and I really, REALLY appreciated that..

What continues to impress me most about this duology is how different it feels from the average romantasy. Yes, there's romance. Yes, there's mystery. Yes, there are secrets piling up faster than dirty laundry after vacation. But the heart of this story has always been trust, healing, and learning that sometimes the hardest battles aren't fought in the world around us, they're fought from within ourselves.

The atmosphere remains one of the strongest aspects of the book. Obsidian Academy still feels mysterious and haunting after 2 books..with its hidden tunnels, dangerous politics, and constant feeling that someone is ALWAYS watching. The author has created a world that feels immersive without overwhelming the reader with endless lore dumps, and I loved how naturally everything unfolded.

Also for me the characters just worked SO incredibly well together..Castien continues to be one of the more refreshing male leads I've read in fantasy lately. His devotion borders on obsession, but it's written with an emotional vulnerability that makes him incredibly compelling rather than simply possessive.. Then we have our Wren, who also continues to grow so much throughout the story. (Even when her choices frustrated me.)Their relationship is built on patience, communication, and emotional intimacy, which was honestly a welcome change of pace from the constant miscommunication and forced drama that often pops up in this genre.

The mystery kept me engaged from beginning to end. I enjoyed trying to piece together the clues, and while I guessed a few things correctly, there were enough surprises sprinkled throughout to keep me second-guessing myself on a regular basis.. The even balance between fantasy, murder mystery, and romance remains one of this duology's biggest strengths. ( And that's a huge strength to have)

That said, this wasn't quite a five-star read for me. Mainly because the pacing occasionally slowed during the middle, particularly when the emotional conversations began to outweigh the forward momentum of the plot.. While I highly enjoyed the character development, there were moments where I found myself eager to get back to the mystery.. it was just too good!..I also would have loved a little more tension surrounding the final confrontation, which wrapped up slightly easier than I would have liked.. especially after such an intricate buildup.. I just feel as if there could have been more and it would have been FANTASTIC! ( Keep in mind I'm also a  gluttonous sob)

Don't get me wrong!..Even with those minor "complaints", this was still  an incredibly satisfying conclusion.. It's emotional without becoming melodramatic, romantic without relying on spice, and suspenseful without losing sight of its characters.. That's a difficult balance to strike, and I think this series accomplishes it remarkably well!

If you enjoy dark academia, beautifully slow-burn romance, murder mysteries, secret societies, and characters whose emotional journeys matter just as much as the fantasy plot, I would absolutely recommend picking up this duet! Personally I think they're absolutely gorgeous inside and out, and I will be adding them to my hardcopy trophy collection.


Until next time

Annah did absolutely incredible in this book!
Her writing and everything about it is absolutely amazing. I cannot stop thinking about Castien, Wren, and Finnick.
I loved everything about it! The characters, the plot, the emotional rollercoaster…I loved it all.

Castien and Wren went through horrible things yet they’re still standing. Because of each other. Because she was his light in the darkness and he was hers. They loved each other so fervently and fiercely, it just melted my heart.
Castien the man that he is!👏🏼👏🏼 He was so loving and patient and caring and obsessed with Wren. His heart belonged to her from the beginning. Even when she didn’t know it.
Wren. She’s amazing. I respect the woman that she has become. I admire the quiet strength that she has and I absolutely love that Castien did his best to show her that she IS strong. That she is NOT broken. That she is enough.
They’re perfect for each other.

Fin, aka my favorite side character EVER, I love him so much. I loved how loyal and caring he is with Castien. Their banter and friendship was one of the my favorite parts in the entire book. And I am so so sorry for what happened to him. But I love that he had Castien to help him survive.♥️
And the ending😭 Don’t get me wrong it was a happily ever after but what was that Annah?😭 I was destroyed. What happened broke my heart and that Castien is blaming himself for it? Broke my heart again. (PS I loved it)
All of them deserved better.♥️ But I was so happy that Wren was there for them.
I absolutely adore this book🥹

favorite moments:
- Castien giving his dagger to Wren
- when she took care of him when he was ill
- when Castien called her ‘Storyteller’ or ‘dearest’
- when he helped her with a panic attack and made sure she was okay to continue their investigation
- Castien comforting Wren after the nightmare
- Castiens letter in her brothers journal
- their first kiss!!
- him rescuing her in the tunnels
- Wren having Castien say “This was not my fault.” 😭
- the epilogue
- “We have forever.” 🥹

Tides, he loved her. He was irrevocably in love with Wren, in the most hopeless manner. Tears burned in Castien’s eyes, a foreign feeling for him after years of suppression. He’d have done anything she asked during the interrogation, not out of duty or justice, but because he loved her. The overwhelming desire to ensure she never cried again was a flower rooted in an entire garden of utter devotion. His heart thrummed, each beat a declaration of his feelings.

This is such a solid dark academia duet in the clean content space. I'm hoping it sets a trend for more dark academia with clean content!

The dark academia vibes are absolutely there. It did feel like the romance is the focal point, and that moving as slowly as it did was awesome. It made total sense for the romance to be the slowest burn given Wren's trauma. And boy, when the romance finally committed it was captivating. Overall, the last 30% had me in a chokehold for the romance and plot. The third act break-up was perfectly paced and perfectly resolved. The way Castien handles Wren's needs in their progression was everything!!! And the plot twist for the serial killer...I did not see coming. The gore around all of that was just enough to be creepy/thrilling but did not cross a line. The epilogue was super sweet.

I have a couple complaints (but the ending saved my rating). Some parts were a little slow and I didn't find myself reaching for the book at times in the first half. I also thought the closure to the mystery in the middle was a little weak. I wanted more from the plot in the first half. I get that the slow build up helped the end be impactful but it still felt like something was missing to me. It is a romantasy though so I understood that it was more romance-forward. The monsters felt like a loose-end. I wanted them to play a slightly bigger part. Lastly, I wish this had been written in first-person. I usually don't mind third-person at all, but this would get a little clunky sometimes with how often the author mentioned the POV's name to tell the story (it’s funny, because this didn’t feel like an issue to me in book 1). I actually started inserting first-person in my head for whoever's chapter I was in and it felt so much smoother to read (the writing style itself is really beautiful). I hope the author considers first person for fantasy in the future.

I'm looking forward to more dark academia romantasy from this author and highly recommend this duet!

4.5/5 stars!
thank you to netgalley and dreamscape media for providing me with a copy of this books ALC!

favourite quotes;
✿ Wren was here for answers, not because of an attachment to him. She did not suffer as he did. It was foolish to hope she longed for him the way he did for her.

✿ ''What is love and affection without the absence of a sound mind?''

✿ Tides he loved her. He was irrevocably in love with Wren, in the most hopeless manner. Tears burned in Castien's eyes. A foreign feeling for him after years of suppression. He'd have done anything she asked during the interrogation, not out of duty or justice, but because he loved her. The overwhelming desire to ensure she never cried again was a flower rooted in an entire garden of utter devotion.

general thoughts
this duology truly is everything i yearn for in books - letters sent between the mcs, academy setting, murder mystery and yearning!! castien truly is down horrendously for wren and im sure he would literally do anything for her that she could ever want - i would go on to say he's honestly borderline pathetic for her in the best way possible

i absolutely love all of the characters that we grow to know and love during this duology and genuinely wouldnt complain for a single second if every single one of them got a book of their own (finn and lu's book.. im coming for you next!) as i truly do enjoy seeing all of them on page. but oh my darling wren how i LOVE you as a character... truly i understand castien deeply because i would also lay my life down for her if she ever even hinted as much would help her...

the narrators voiced this book to perfection too - they took an already incredible book and made it even more enthralling! i would absolutely love to check out more of their work in the future!

"We have forever."

Tides of Secrets by A. R. Conwell

Dearest Ms. Conwell,

I'm sitting here in utter shock. Words have completely fled my mind. Because no words can adequately describe the beauty of the ending of this beautifully poetic duology. 
Healing from emotional scars. Devastation. Mystery. Moody atmosphere. Yearning and exquisitely elegant romance.

Castien and Wren together are perfection. I felt so many emotions while reading this book. The healing from her scars is so tenderly cared to by the author through Castien's deeds and words; I found my heart aching and healing right alongside her, though I have never experienced the same type of heartache and hurt.
How she helps him to begin to heal from his grief and self-guilt is also beautifully done. I loved them working together to solve the mystery enshrouding the academy.

The set of side characters who made up their friends were so well written, who can't help but long to see them get their happy endings and their own POV stories.
Even the villains were well developed and will really surprise you. I had no idea how everything would play out in the end.

Very perfectly done Romantasy I will be reading over and over again in the future. I wish I could give it more than 5 stars because it definitely deserves all the hype and love! I highly recommend this one and the first book to anyone ages 16+, unless you are sensitive to certain topics. See my content guide.

Yours,
Holly

Sigh.

I was looking forward to this story and to the resolution of the romance and mystery, and to Wren coming to terms with her traumas. Unfortunately, I am leaving the story largely unsatisfied. I appreciate , but the romance became too lovey-dovey for me. It didn’t feel as sincere as I know it could have. It was like the writing was trying too hard. The writing style was often good, thoughtful, or effective, but other times it veered into inauthentic territory. I am not sure the rest of the story and what Wren was grappling with matched the cheesiness.

Another big factor to the romance disappointing me was that Castien didn’t have a character arc or enough flaws, and he couldn’t find fault with anything Wren did, and there just was not enough of a dynamic left between them. I don’t need constant friction or anything, but were not enough to carry the whole romance to the end of the book. Maybe they needed a C-plot to focus on while the A-plot was dormant.

The side characters were barely there. This book was mostly just Wren, Castien, and Finn (and Heathcliff/Blossom, I guess), and I think that was a mistake. Her other friends did a lot for the first book, and so did the professors. I don’t know. It was easy to forget that they were in an academy taking classes.

We also had zero resolution with

Am I nitpicking now? Do I need to be stopped?

I enjoyed the first 30-40 percent, but after that I just slowly stopped caring. I wanted to love this, but I did not. Even so, I liked Ocean of Ink enough I will give the author another chance.

I had the privilege of proofreading this, and IT IS SO INCREDIBLE! Literally had me sitting in my feels after I finished it.

You will find murder, death, and vague recollections of s*xual abuse in this book, but there is SO MUCH BEAUTIFUL HEALING as well.

March 18, 2026
thank you SO much A R Conwell and her team for the privilege having Tides of Secrets as an ARC. I absolutely loved being in the halls of the Obsidian Academy again. Book releases March 31st.

Below is my honest review:

5 stars!

This was STUNNING.

This is the second book in the Obsidian Academy duet and we pick up right where we left off. Wren is navigating a web of murders and stolen secrets while deciding who she can truly trust. As the shadows within the Academy grow more lethal with more of the Order murdered, she and Castien are forced into an uneasy alliance to unmask a killer with a unique calling card hiding in plain sight. It is a dark academia romantasy that balances a slow-burn, enemies/rivals to lovers romance with yearning, a desperate hunt for the truth, and to defeat the haunting ghosts of past traumas. The murder mystery had just enough clues to keep me guessing without it feeling predictable. The side characters were excellent I absolutely adore (names redacted bc of potential spoilers), but my absolute favorite part of this book was the thoughtful and attentive romance.

Castien and Wrens romance was EVERYTHING I wanted and more especially after the build up we saw in Ocean of Ink. They’re truly one of my new favorite book couples. They felt like a blend of Elizabeth and Darcy (Pride and Prejudice) and Ella and Kit (live action Cinderella) in the best ways. Their romance was just so real and raw and intense. They supported each other and shined light into each other’s darkness. Castien was absolutely obsessed with Wren and his love for her was so patient and so caring. The yearning? I can’t. I absolutely adored him. Wren was also so thoughtful with quiet strength that grew into confidence and an ability to help Castien process grief. Her story was handled with sensitivity and care and protection. I consumed their letters and Castien’s terms of endearment like air in my lunges. His storyteller. My dearest. My dear storyteller. Your sword and shield. My love. IM SCREAMING. Their first kiss !!!!!!!!!!!!

Hey, Annah… you know what you did at 85% and it wasn’t nice and I just need you to know I’m still brokenhearted.

Do we have a certain side character and cousins book on the horizon to look forward to? PLEASEEEEE.

TW: rape/sexual assault (recounted), past traumas, grief, loss, murder, mystery, violence, descriptions of blood and wounds, battles, weapons, mental health struggles, depression, anxiety, haunting emotional trauma, emotional recovery, no language, no spice - some kissing

Enemies/Rivals to lovers. Slow burn. Found family. Forced proximity. He falls first. Third person POV. Dual POV. No spice/closed door.

Overview:

Language 🤐: None

Romance ❤️‍🔥: LV 2-3 kisses only (longer slightly descriptive kisses)

Violence ⚔️: On Page Death, fights, blood mentioned, pg13 I’d say I didn’t feel like it was not overly descriptive but could be upset to some

⚠️Alludes to SA, Grief, Death, the author has a warning at the beginning and does have content you can look up on her website to have a heads up before reading ⚠️

Tropes/Micro tropes
- Dual POV
- Feminine, soft but strong FMC
- Protective MMC
- He Falls First and harder
- Found Family
- Teachers her to use a knife
- Letter Exchanges
- Journal Entries
- The love confession 😍
- Do anything for her

My Thoughts:

OH HOW I LOVE THESE! This duology is definitely a 6⭐️ one for me! I absolutely loved these so so much! There was so much depth to these characters. The twist and turns as well as the exploration of dealing with grief was amazing.

Wren is just such a wonderful female character. I feel like most FMC are strong and Wren definitely is in her own way but she’s one of the most feminine FMC I’ve read in quite a while and I absolutely love it. She has a soft presence and personality but such depth and strength that I never felt like she was weak even if she was more so weak in a physical sense. I loved her dedication to growing stronger in many forms of the word throughout this series.

Oh Castien what a wonderful MMC! The absolutely YEARNING of this man! He was so far gone for her and it was delightful to see that continue throughout this second book! He is so sweet, gentle and protective of Wren. His obsession for her was sweet, in some books I feel like the obsession can be overboard but with Cas’s yearning and love for Wren idk it just worked so well and beautiful.

The letters 😍

“We will walk along the shore together”

“We have forever”

Ugh 🥰🤩 like I cannot get over these two! They seriously looked into the darkness of one another and brought the light.

I felt like the struggles were explored in such a beautiful way, it did not tamp down the darkness but showed the joy and light that can combat it and bring happiness even after the darkest of times.

I laughed and I cried during this book and just cannot say enough good things! Can’t forget to mention my love for the side characters. Cannot wait for Veil of Deceit to come out, Finn was definitely a highlight for me. But seriously what a great cast of characters who I hope we will see more of!

Just loved these so so much!

Giving this 4 stars because I did enjoy reading it; however, I don't love it as much as others seem to, and probably for personal reasons more than anything.

The writing style was a bit of an issue for me in both of these books. I feel that the author was trying to make it feel fancy and formal, and as a result, much of the dialogue felt stilted to me. There was a moment in the book where she dropped that, and it was the most genuine scene in the book, in my opinion.

Second, Castien's love for Wren definitely leans more toward obsession than I typically enjoy. I get that his gift makes him prone to that, but there were times it was a bit cringey to me.

As far as content goes:
I've seen multiple bookstagram reviews and recs for this duology, and most don't mention the references to past SA/grooming that are very present in these books. It's nondescriptive; however, it is woven throughout the books, along with the aftermath of that - dark self-talk and thoughts of self-harm, for instance. The author does note that it's dark romantasy at the beginning, and she has a list of TW on her website.
It's also moderately violent, with frequent talk of death (it is a murder mystery, after all) and some descriptions of bodies and wounds. I don't mind a darker story, but if you're sensitive to that kind of content, be aware going in.
No-spice: kisses only, thoughts and feelings of desire.

I realize this doesn't really sound like a 4-star review... I did think the premise and overall storyline of this duology were very interesting, and I enjoyed most of the characters. I'll read the next books set in this world. It kept my interest, and I read it quickly. Just a few things that kept it from being a favorite for me.

The second book in a dark academia romantasy Duology. Book one was certainly stronger than book two and I feel a bit let down. This duology is marketed as adult but heavily reads as YA (nothing wrong with YA at all, and this is not a criticism of the genre!) which just felt misleading/confusing. The characters are adults (early 20s?) but they’re attending an academy (in which zero class work or schooling actually takes place) and there’s a murder mystery that somehow has the most boring discovery of all time..the two main characters are writing letters to each other rather than just talking about things while together and this feels very juvenile. Also the amount of giggling and smiling was a bit much for me 😅

My biggest issues with the FMC are that she was presented as innocent and naive in book one but very capable, while book two she’s just so fragile, constantly fainting/crying, and just overall has the demeanor of a young girl constantly needing saving. The amount of times the MMC describes the FMCs hair…we get it dude..you think she’s pretty.

I initially soft dnfed this but wanted to give it another try on audio which I do think enhanced the experience because the dual narration is well done, but idk if it was worthwhile to pick back up. I think people who love a YA romance with yearning will enjoy this duology but it didn’t quite work for me.

This book made my heart so full, then broke it, and gently put the pieces back together.

The only way this audiobook could’ve been better is if it were done in duet. Even so, Alys Wilde and George Reid were phenomenal. Alys Wilde’s accent fits romantasy perfectly, and George Reid’s range made Castien and Finn feel so distinct and emotional.

The book is labeled dark, most likely because it deals with heavy and sensitive topics from Wren’s past. These moments are shown through memories or journal entries and aren’t graphic, and the overall tone still feels gentle and focused on healing.

This is a book that does yearning right. You feel the longing in a glance, in a brief touch, in sweet endearments like "my darling" and "my love". It’s a slow and vulnerable romance shaped by internal wounds and emotional recovery.

The first part follows the continued search for Heron’s murderer while Castien slowly realizes he’s in love with Wren. The second part shifts into the emotional fallout of the stolen journal. It’s heartbreaking because his love is so clear to the reader long before she can see it herself.

The letters are the heart of this series. They’re where trust is built, their friendship develops, and where they could be vulnerable. Every endearment made me giddy. The letters after the truth came out were so lovely. Castien's raw honesty and love declarations literally made me cry. He showed up for her in the only way he knew how, writing to her every day and trying to make things right. His love was stronger than the monster living in Wren’s internal monologue. And I really loved that they keep writing letters even after they’re married.

One of my favorite things in any book is when characters actually do the work to heal from their trauma instead of just getting over it. This series handles childhood trauma with so much care. Castien doesn’t fix Wren. He supports her, shows up for her, and helps her slowly change that internal voice that insists she’s unworthy. She learns she’s not broken.

As a side note, A.R. Conwell has letters after the wedding available on her website!

Finn was my favorite side character. He brought so much levity that almost every scene with him made me smile. I’m excited to read Finn’s story when it comes out.

Thank you NetGalley, Dreamscape Media, and A.R. Conwell for this ALC

📝 Review/Notes 📝

Oof, I really don’t like “dearest”, especially from 20-24(?) year-olds. Repeated use of that nickname (from both of them) was a major ick for me.

I'm a bit unsure how to feel with this one, after the first. Getting into the first book, I was excited to find a lot of things I really liked about it, and felt like it was going to be a highly underrated duology to recommend. However, I'm not sure this one really came through, and in the end I wouldn't rate it as high as I thought I was going to.

I do still like the duology overall, and I think there are a lot of promising elements. I just couldn’t 100% get past my ambivalence and nose wrinkling towards the h, and how other characters were so devoted to her without any real reason. She hasn’t been particularly interesting or anything really to inspire the loyalty she has from Finn, Castien, and Kierana. And she regularly acts annoyingly or immaturely–like of course she would refuse to read his letters.

This one leaned heavier into the sappy & lovey-dovey side of romance, with him turning into a full on yearning, down bad, sad sack for her, and her own “realization” of her feelings coming somewhat underwhelmingly and kind of quickly after her thoughts around not even understanding the emotion. From *what on earth is that* [love, desire, etc.] (come on girl, I know you’ve experienced trauma, but you’re 20 years old) to “I love you so much”. For those reasons, this was more good than great.

I agree with a lot of what Goodreads reviewer Sara says in her 2-star review.
"...but the romance became too lovey-dovey for me. It didn’t feel as sincere as I know it could have. It was like the writing was trying too hard. The writing style was often good, thoughtful, or effective, but other times it veered into inauthentic territory. I am not sure the rest of the story and what Wren was grappling with matched the cheesiness.

Another big factor to the romance disappointing me was that Castien didn’t have a character arc or enough flaws, and he couldn’t find fault with anything Wren did, and there just was not enough of a dynamic left between them. I don’t need constant friction or anything, but The Big Lie trope and Castien’s unending patience were not enough to carry the whole romance to the end of the book. Maybe they needed a C-plot to focus on while the A-plot was dormant.

The side characters were barely there. This book was mostly just Wren, Castien, and Finn (and Heathcliff/Blossom, I guess), and I think that was a mistake. Her other friends did a lot for the first book, and so did the professors. I don’t know. It was easy to forget that they were in an academy taking classes."
^^^ This! All of this!

Another thing I found kind of sus–for all Castien’s supposed strategic brilliance, I was surprised that he, in particular, was willing to accept

Anyway, this conclusion to the duology was not all that I wanted it to be, but I see the promise in it, the stronger elements, the strong writing, and I definitely will read more by this author and am excited for Finn’s story, as he’s a favorite.

I did find something out looking at other reviews and the author's note...I saw the phrase "embodying biblical love" used both by the author & (a) reviewer(s), and I have to be honest, that's an ick for me. Perhaps that is why I struggled with the h/FMC, if she was supposed to embody some sort of "good Christian girl" ideal, wherein everyone around her was drawn to her for being meek and delicate? Also realizing now that is probably what some of the obsession around "purity" in this duology came from. I have no problem with a clean romance, and there has to be something for everyone. I'm glad there weren't strong religious overtones in this duology, but I do wonder if some of that "biblical love" ideal seeped into some of the things I found frustration with, like the naivety of the h, the lack of character arc from the H, the sappiness, and the missing tension between the MCs.

This really should have been one book since #1 rolled right into #2. I liked this academy setting - magical elements but not necessarily a magic academy. The mystery aspect was pretty simple. What sold me was the YEARNING lol. I love a dual POV and Wren and Castien's letters to each other were perfect. And the banter, eek! It was sweet and wholesome, but also appreciated how Wren had to work through some really heavy burdens. Their relationship reminded me of Roman & Iris from Divine Rivals so lots of swooning for me.

A fulfilling and heart pounding resolution to the Obsidian Academy Duet! While I loved Ocean of Ink, this book was by far my favorite of the two. Watching Wren work through the difficult things in her past and how much Castien loved her through it just melted my heart.

The poignant themes of beauty amidst pain and hard things shine bright lights into these characters lives. Wren and Castien both grow so much throughout this book and I loved their romance so much! I loved Finn almost more than any other character, his tender heart and humorous quips added some levity to this book full of twists and turns.

I can’t wait to reread this series so I can annotate all my favorite parts!

CONTENT CONSIDERATIONS
Mentions of death, murder, and grief. Grief of a sibling (past loss), brief descriptions of bodies being mutilated after death, depictions of panic attacks/anxiety.

I receive an ARC copy of this book, all thoughts and opinions are my own.

My Rating: 3.5 / 3.75 stars (Series overall: Solid 4 stars)

Writing this review for Tides of Secrets, the second book in The Obsidian Academy series, is honestly a bit hard for me.

I absolutely loved the first book. Compared to a lot of the YA Fantasy I’ve picked up recently, the debut really stood out from the crowd. For most of this sequel, I thought we were on track for the exact same experience. Up until about the 75% mark, the story was completely delivering and holding my attention just as well as the first one did.

And then, everything just went wild—and not in a good way.

The last 20 or so pages felt completely lost. It was a chaotic mix of unnecessary drama, a massive rushed plot, and surprisingly bad dialogue. To be completely honest, the shift was so jarring it felt like someone else entirely stepped in to write the ending.

Because the foundation is still so strong, the series as a whole remains a solid 4 stars for me. But this specific one drops to a 3.5 or 3.75.

Thanks, NetGalley, for the ARC Copy.

Wow. Just. Wow. This book was devastatingly beautiful 😭 🥀 AR Conwell’s poetic prose had me gripped from the moment this book opened through the epilogue 🪶 and I’ve found myself thinking of these characters constantly since finishing the book 📖 I miss them already 🥹

This is the second book in the “Obsidian Academy” duet 🌊 Check out my review for book 1 “Ocean of Ink” 🌊 in my highlight reel for ‘25. Trust me when I say this one is so so good ✨

For the sake of not spoiling I’ll write some of my favorite moments 💖

Wren and her dagger 🗡️
Finn’s entire existence 😏
Castiens YEARNING 🪶
The letters 💌
Sick scene 🔥
Nightmare scene 🥹
“In chains” 😩

If you love fantasy at all you NEED to read these books 🌊

3.25 stars

I listened to this book on audio and the narrators, George Reid and Alys Wilde, did a decent job bringing the story to life. It is in dual narration and I wasn't a fan of George's voice for the FMC, Ren. It also start off very montone and parts of the book had a lot of extra mouth noises. 3 stars for narration.

As for the story itself, book 2 could legitimately be the next page in book 1. So definitely be sure to read the first book. I actually really enjoyed book 1 and was a bit disappointed with Tides of Secrets. While the story continues easily into the next book (without giving quick summaries to what previously happened), it felt like a different book. In the first book book, the professors and other students played a major role, not so much in this one;they actually felt like an after thought at times. The romance between the FMC and MMC became more of a focal point to where it kinda became a hindrance. There was little character growths with Castien (MMC) and he saw zero flaws in Ren, everything she did was perfect. The academic setting was in the forefront of book 1 and became just background noise.

The ending was a bit unsatisfying in how it was done. It felt like the ending was so drawn out it took up 40% of the book. It does neatly tie everything up but it took its sweet time getting there. And the final villain was a bit.. disappointing.

Overall it was a decent duology. If you are looking for a quasi-academic mystery romantasy novel with minimal spice and a unique magic system then maybe.

Thank you NetGalley, A.R. Conwell, and Dreamscape media for giving me an ARC of this audiobook in exchange for my honest review.

Ugh I loved this!! The romance was exceptional. Castien yearned harder than Kai Azer himself, and even though Im usually annoyed by male characters like these, Castien (and Mr. Darcy) are currently my two exceptions.

My thoughts:
OH MY GOSH! How do I even put into words how amazingly beautiful this book is? Everything about this book was so beautiful and emotional. The writing was amazing and drew me in immediately. It was so utterly addicting to read.
Castien and Wren’s relationship is so sweet and I love them so much. They have a special place in my heart, as one of my favorite book couples.
The emotion in this book was so intense and I loved it so much. There were so many twists and turns to this story and I never knew what was coming.
This story has been on my mind since finishing book 1 and I’m so glad to have an ending to the story.
I highly recommend and can see myself rereading many times in the future.
I’m also so excited for a certain someone’s book next…

ARC Review: Ocean of Ink was a wonderful book that laid the foundations for the masterpiece that is Tides of Secrets. I’m not sure I’ve come across a duology where I feel the second book was better than the first, but here we are. This story has you experiencing all of the emotions. Grief. Sadness. Fear. Joy. Heartache. Betrayal. Love. Happiness. I was so impressed by this darker academia book and the characters within. What a fighter Wren is! She was a lovely FMC who pushed through her heartache to find a family of friends amid terrible circumstances. But Castien, what a wonderfully written man. His words were true poetry. I tried to pick a quote out of the abundance in the book and simply found that I could not choose. There were far, far too many. The most attractive part of his character was his gentle, but all consuming obsession with Wren. What a beautiful love story. Well done, A.R. Conwell. I cannot wait for Finn’s story. I am greedy for it.

I'll be the first to admit that romantasy is not exactly my favourite genre. But the Obsiodan Duet by A.R. Conwell? I ate that shit up. I love me a slowburn romance that doesn't centre on horny pining, but really focuses on the characters, their struggles and their healing. A MMC who says "I don't care if we never sleep together as long as you are in my life, and we get to talk and write letters to each other"? I think I fell in love with Castian right there and then.
The narrators were once again phenomenonal and really brought the characters to life.

The plotpoint with the murders was a bit predictable and I did expect more from Castian with his gift, and there was a bit of a lull in the story which felt off in the pacing (I thought we were nearing the end and there were like 2 hours of audiobook left to go), so 4 stars.

Ocean of Ink was four stars, but this conclusion is 🌟🌟🌟🌟🌟.

I kept thinking to myself "this audiobook is so good." The narrators are incredible. It was so enjoyable to listen to.

The second book in this duet picked up right where the first left off. The killer is still on the loose and Wren and Castien need to use their gifts to catch them. Their (proper) banter continues to be a highlight.

Pick this up if you like:
Solving a mystery
Letters
Historical fantasy with magic
Healing
Royalty
He falls first and hard
Groveling
No spice or language

Although the story is wrapped up in this duology there will be more in this world. The fun rakish sidekick, who we know from the first two books, will be the main character of the third. I love him so that makes me even more excited to continue. Veil of Deceit publishes on June 30. But the first duet is out now.

This story is slower paced so if you are craving high intensity with a lot of action, this won't deliver that.

Check trigger warnings.

Words escape me. This was PHENOMENAL. If you’re looking for a series with tension, banter, swoon, and found family…. Look no further!

This was perfection! I can’t say much without spoiling anything, but between the romance and the mysteries, you will be on the edge of your seat!

I NEED Finn’s trilogy now!

Another fab book. I do think the mystery side arguably leads something to be desired but i can't complain as I still devoured this.

The characters are fantastic. I love the whole group and I love our main couple. I am excited to try the next books that focus on Finn but I am BEGGING for more Kierana and would love to see her romance develop more hehe.

Wow talk about an upgrade from book one to book two....

Ocean of Ink was not a bad book by any means but it wasn't spectacular imo either.

THIS BOOK THOUGH?????

Holyyyyyyyy crap dude...

This contained SUCH good romance. The yearning, loving tendencies, caringness and overall themes were beautiful 🥺❤️

Honestly, the romance kinda carried the story in the middle but the ending was pretty good too.

Castien and Wren are PRECIOUS and Castien literally has a small price of my heart bc omw this man LOVES Wren wholeheartedly like dang 😩🤌

Also I actually love Finn sm and I'm so excited for his duology. ❤️❤️

The main plot was overshadowed by romance sometimes and maybe just a bit messy, but overall amazing.

My heart was thoroughly warmed by this book and especially Castien's letters and love towards Wren. my jaw literally dropped a few times by things he said like ok caring-totally infatuated- kingggg 😌✨

Anyways yeah this was such a good time!

4.75 ⭐
Would absolutely recommend!! 💖
