Thank you to NetGalley, HarperCollins, and HarperCollins Children's Books for this advanced copy.! You can pick up A Theory of Dreaming on July 29, 2025.

Ava Reid once again sweeps us away to a magical, war-torn land where truth and myth intertwine. After rereading A Study in Drowning, I found myself excited to return to Llyr and learn what our two protagonists encounter as they try to prove Angharad wrote her book.

This story definitely started a bit slower for me, as Effy and Preston navigate troubles within the University and public backlash against their project, For me, the middle is when things picked up and we saw the consequences of Effy and Preston's actions hit even harder. Effy, the first woman to be accepted to the literature college, faces rampant sexism and misogyny in her classes, and yet still seeks to tell the buried stories of young women and, specifically, female authors.

Preston, meanwhile, is having a literal magical episode that transports him to an underwater palace in his dreams. But when his dreams begin to conflate with the real world, it could have a devastating effect on the ones he loves.

I loved the ending of this story and the overall growth we see from Effy and Preston throughout the two books. If you're looking for a lush, gothic world full of academics and dreamers who fight for a better life, this is your book!

I found A Study in Drowning to be rather disappointing, but I had hopes that getting more of Preston's side of things in A Theory of Dreaming would make this more interesting. Ava Reid is a good writer in her prose, but the plot and characters are lacking in this world. I was extremely bored. I may try again at a later date, but at the moment, this just isn't for me.

I am still going to try her other book, Fable for the End of the World because that premise seems interesting. If that doesn't go well, then I'll know Reid just isn't the author for me.

4⭐️ Ava Reid never disappoints with her writing. In this one we continue on with Effy and Preston as they return to university and we get to see the aftermath of what happened in A Study in Drowning. Effy goes through so much being the first woman admitted to the literature college and the feminine rage inside me was fuming. 😤 But I wasn’t the only one… We get to see a very protective side of Preston in this one. Although it is dual POV I feel like he’s more so the plot of this one.

☁️ The world building in this was stunning I could really picture and envision this fantasy world that her and Preston created. The writing was so beautiful and poetic. So many great quotes in this.

💙 The romance was so cute and sweet and wholesome 🥹 Preston is just the kindest most perfect protective boyfriend. My poor girl Effy goes through so much and he’s so supportive.

Please check your triggers before reading this ❤️‍🩹

A Captivating Conclusion to a Dark Academia Duology – 4.5/5 Stars

A Theory of Dreaming by Ava Reid is a stunning and thought-provoking sequel to A Study in Drowning, bringing Effy and Preston’s haunting journey to a poignant and satisfying close. Reid’s lush, immersive world-building and her ability to blend dark academia with elements of fantasy are on full display here, making this a must-read for fans of the duology and newcomers alike.

Effy has finally found a place for herself after the tumultuous events of A Study in Drowning, earning her spot at the prestigious literature college. Yet, even as she attempts to settle into her new life, the shadow of her past—and the dangerous, unresolved nature of her dreams—looms large. The pressures she faces as the first woman to enroll at the college and the weight of national expectations create a suffocating atmosphere that perfectly mirrors the internal conflict of the novel.

Preston’s journey is equally compelling. As he begins to experience vivid dreams of a palace under the sea, his descent into his own nightmares feels inevitable, and his struggle to maintain his identity in the face of such powerful visions is hauntingly relatable. The tension between Effy and Preston as they navigate their shared and individual dreams, identities, and desires is palpable and deeply emotional.

Reid’s prose is lyrical and evocative, with a dreamlike quality that immerses readers fully in the narrative. The symbolism and themes of dreams, identity, and the nature of fantasy are explored with intelligence and nuance, making this book more than just a fantastical love story—it’s an exploration of self, of facing the truths that haunt us, and the danger of losing ourselves in a world of dreams.

The pacing is steady, though some readers might find it a bit slow at times, especially in the first half. However, the build-up is worth it, as the climactic conclusion ties together the novel’s thematic and narrative threads in a way that feels both satisfying and tragic.

The only reason this book doesn’t earn a full five stars is that at times, the complexity of the world-building and symbolism can feel a bit overwhelming. It’s a book that asks its readers to engage deeply, and while that’s part of its allure, it can occasionally distance readers who are looking for a more straightforward narrative.

Overall, A Theory of Dreaming is an evocative, emotionally charged conclusion to Effy and Preston’s story, filled with layers of meaning and rich in atmosphere. Fans of the duology will find this finale incredibly rewarding, and anyone who enjoys beautifully written, thought-provoking fantasy will be drawn into Reid’s spellbinding world.

I think I’m more confused after finishing the book than I was reading it. I still don’t know why or how some of the things that happened actually happened. There wasn’t a whole lot of plot. I wanted to see more of edgy and Preston as a healthy functional couple. The writing is beautiful and it definitely has potential but I felt like it was missing something important.

Just as beautifully written as the first! I know this series isn’t for everyone; it’s not a big, loud, intense story with action and drama. It’s a quiet somewhat-fantasy with beautifully flawed characters that don’t ever “figure it all out.” It’s realistic in a way that doesn’t feel overwhelming, and fantastical in a way that it still provides an escape.

If you’ve read the first one, I definitely recommends one!

This was the PERFECT follow up I needed! Effy’s struggle throughout were incredibly heart wrenching yet real, and anyone who has ever struggled with mental illness will feel seen by the way Reid writes it. Excellent, excellent, excellent!

Thanks to NetGalley and HarperCollins for this e-Arc!

Ugh what a hauntingly beautiful sequel to “A Study in Drowning”. The way Ava Reid conveys such deep and profound meanings in her writing style always amazes me!

Powerful themes. Perfect pacing. Poetic writing.

I loved getting to see more of Effy and Preston, though sometime I was SOO frustrated with them both. PLEASE just communicate! 😂 I wanted a bit more from their character arcs.

Even though I loved this book so much, ASID truly has me in a chokehold. Which is why I’m giving this a 4.25 star.

I liked this one but not quite as much as the first. Part of my issue was that it was so depressing for so long. My other issue was that I never really knew what the main issue was. The first book had me so sucked into it and for so much of this one I wasn't sure what I should be focusing on. The wrap up also felt pretty rushed at the end, but overall, I still liked it and will continue to read Ava's books because I like the world-building.

I got to step into this world again and it was such a beautiful experience. I felt my mood sway with this book, taking in what both of the MCs were feeling.

Effy is one of the most relatable characters I’ve come across in a while. We got to see her be really strong and accomplish so much at the end of book one and a lot changes in book two. In most cases we assume that everything gets better after the HEA at the end of a book, but this is real life (well as much as a magical world can be). We watch her question and have heartbreaking conversations with herself. All the while Preston believes that he isn’t worthy of loving her. He cares so deeply for her while she was falling apart and she didn’t want to burden him so he didn’t even know the half of what she was going through mentally. When her mental health finally came to a head I nearly broke down with her. That poor girl had so much dumped on to her and she didn’t know how to pull herself up from the bottom of the well.

When I finished book one, I feared that the Fairy King wasn’t actually dead and that Preston would become the new host. This fear was fueled by the rage that kept building in Preston, prior to this he was so passive. Once it became clear that he was changing due to this dream world, I started to remove that idea from my head. That other world brought so many other issues to his life and it was hard to watch him slowly lose himself. Once I noticed the correlation between his vision and how deep he was, I began to stress over his sanity. For example, when that clear vision translated into the waking world I was terrified we were going to lose that sweet boy for good.

I loved the way Preston is able to tear himself away from this welcoming false world, that is crumbling the very life he fought so hard to achieve, by doubling down on Effy. He is the sweetest boy and I’m so sad that I won’t get to see him again (until I reread).
It feels weird to say that I’m proud of these two, but I truly am. They feel like a part of me and I love them dearly. I’m excited to jump into other books by Ava Reid. The connection I made to these two characters is something I will cherish.

A Theory of Dreaming shifts away from the gothic romance of A Study in Drowning and plunges into a sharper, more political story. Effy and Preston must grapple with the weight of the truths they've uncovered--navigating a world steeped more in exhaustion and existential dread than overt magic. The novel excels in its beautiful prose and deeply human character interactions—particularly the miscommunications between Preston and Effy, which feel painfully real. While the story’s structure is more fragmented and lacks the softness of its predecessor, it still captures a rich academia atmosphere. Though A Study in Drowning could have stood alone, fans of Ava Reid’s writing will still find much to appreciate in this introspective and unsettling sequel.

Thank you to NetGalley and the publisher for the ARC.

3.8⭐️ I’m a bit torn on this because, on one hand, Preston and Effy’s love story was so romantic and so precious that I constantly found myself smiling. Ava Reid’s writing is so beautiful and poetic that I was constantly highlighting things in my Kindle.

The story kept me interested, but I didn’t quite see the need for this in the first place because the first book ended with all loose ends tied up. Nothing really happened for the first two thirds of the book, and when things ramped up in the end, it wrapped up so quickly that I didn’t realize there wouldn’t be a third book until I read the acknowledgment and reviews. That being said, it was still an easy read, I just was hoping for a little more action in the fantasy subplot of this.

Overall Rating: ⭐️⭐️⭐️⭐️⭐️

Wow, I have so much to say about this book! Effy and Preston are back at university after the events of A Study of Drowning. While Effy is dealing with the burden of her reality, Preston is slowly losing himself to his dreams.

This book touches on themes of sexism, nationalism and war, mental health struggles and recovery, and the sacrifices of love. The writing is just as beautiful as the first book and the ending of this duology definitely made me cry. PLEASE read this book!

I really am struggling with this review! I loved A Study in Drowning, I loved the writing, the academia, the use of study and inquiry to dismantle beliefs, but the follow up just didn't leave as much of a mark.

My biggest issue with this book was the pacing, it was just so slow. I have been cruising through books and this one put me in a bit of a slump. Preston's POVs were interesting, but I just couldn't grasp why if he was so in love with Effy, why he wasn't telling her anything (and SPOILER literally never ended up telling her anything) the whole book. Effy did the same, it was just not as captivating as the first.

I also am still so confused why there was even a war? The resolution of that fell short for me as well.

Thank you NetGalley and Harper Collins for the eARC ✨

3.5 ⭐️

A Theory of Dreaming picks up where A Study in Drowning ends. Preston and Effy now are facing down the repercussions of unearthing knowledge.

This one leaves being the whimsical, gothic, romantic world from the first book and are thrust into a sharper, more political descent into madness. This book delves more into the countries histories and whether or not magic exists. But it’s not heavy on the magic, more so on the stress/exhaustion/depressive induced escapism.


I think that the stories could have flowed together better and kept the softness and consistency the first book had. This one felt like i was being told 4 different stories in one and it made it not as enjoyable of a read. You can expect the beautiful writing of Ava Reid from this but I think A Study in Drowning could have easily been a standalone.



Thank you Netgalley, Harper Collins, and of course Ava Reid for the opportunity to review this story.

We're back with more magical elements and mystery, this time led mostly by Preston. Effy was a slight disappointment here, most of the book she gave into weakness and intimidation, but after remembering what she went through in the first book I could understand; but that doesn't mean I didn't wish her stronger. Preston's love and devotion for her carried this one for me, he too was going through his own difficulties but was still trying hard to be present and caring. Both of them needed to be more honest with each other though, after book one you would think they could have an open discussion as to what was going on with Preston and the underwater palace. The mystery of another Sleeper being found to not be all their work was interesting as well and I wish Effy had been able to do more to uncover it even further, there were so many questions and speculations to things that we didn't really get answered. Overall it did wrap up nicely but I did wish for maybe a longer epilogue or a slightly different one than what we got, it was nice but a bit unsatisfying to me.

First things first—huge thank you to NetGalley and Harper Collins for blessing me with an ARC of Ava Reid's A Theory of Dreaming! ✨

Alright, besties, buckle up because this book was an absolute fever dream—in the best way possible. Ava Reid's writing is so hypnotic and lush; every sentence felt like falling deeper into a hauntingly beautiful dream world. The vibes? Immaculate. Dark academia meets psychological thriller, with a sprinkle of eerie fairytale magic.

The characters were complex, messy, and heartbreakingly real. Preston and Effy's relationship was such an emotional rollercoaster—beautifully messy, intense, and full of raw vulnerability. Watching them navigate their struggles and fears together added a depth that had me fully invested. Effy, in particular, was someone I deeply connected with; her internal battles, anxiety, and constant questioning of her own reality resonated with me on a deeply personal level. Seeing her journey of self-discovery felt both painful and validating—honestly, her struggles felt like holding up a mirror to my own experiences.

Preston, too, hit me right in the feels. His struggles with self-worth, pressure to succeed, and the weight of expectations reminded me of the burdens many of us quietly carry. His vulnerability and authenticity made his character incredibly relatable and easy to root for.

I was living (and occasionally sobbing) for their journey. Honestly, my emotions are still processing the stunning twists and THAT ending—I might need therapy, thanks Ava!

This isn't just a book; it's an EXPERIENCE. If you love stories that leave you questioning reality long after the final page, you NEED this on your TBR.

Five dreamy, starry-eyed stars ⭐⭐⭐⭐⭐. Ava Reid officially owns my soul.

Thanks to NetGalley & HarperCollins Children's Books for the early copy in exchange for an honest review. Sadly, I DNF'ed at 20% of the way through.

I really loved the first one so I'm not sure went wrong here!

The academic drama was kinda dull and overall it just lost its spooky mystery atmosphere from the first one. Preston's POV should have been great but he was dull as rocks. Maybe in the future I'll re-read the first one and try to finish this one but it was a bummer. I don't think it really needed a sequel.

5⭐

This has to be the most emotion Ava Reid book I've ever read! She did not like when she said that this book made her cry while writing it. I cried like a baby while reading it and it still haunts me. This was more of Preston's book and I love how we explored his background and current situation. Their struggles and differences not seeping through their romance was my most favourite part of the book. They're in reality, some of the strongest characters ever written about and I love the new cast so much! Can't wait to read more by Ava Reid!

Ava Reid does it again in book two. I love this series. I love these characters I love the writing. How is no one talking about this?
