A Theory of Dreaming by Ava Reid is a beautiful and organic continuation from the prequel, A Study in Drowning. We immediately pick up where the story left off with Effy (FMC) and Preston (MMC) as they’re navigating their lives back at school while dealing with the backlash of their discoveries.
The political intrigue is thick and pulls you through the story as you watch both MCs struggle with their mental health. Effy is fighting against a system that doesn’t value women in a scholastic arena, which easily feeds into feelings of inadequacies. Preston struggles with the biases against his culture, among other things. I enjoyed viewing the story more from his perspective this go around.
I love Reid’s prose. It’s dark, moody, and poetic. There were quite a few instances when I stopped reading to think about or write down a beautiful quote. If you enjoyed A Study in Drowning, I highly recommend this book for you.
Thank you NetGalley, Ava Reid, and Harper Collins for sharing an ARC in exchange for an honest review.

Ava Reid’s prose and characters continue to be fantastic, but I didn’t find myself in love with this sequel. A Study in Drowning had a little more mystery and overall plot, and I found this one to be less engaging and I had to remind myself to get back into in and finish.

Overall the story had impactful themes of mental health struggles, government propaganda, sexism in academia, and so many more. Again, the prose itself is fantastic. There were many of the more subtle conflicts that were more profound to me than the larger plot points. Maybe that’s why it feels like, to me, it was a collection of impactful scenes that all wanted to start down their own paths instead of going on one journey.

This is by no means a bad book, I just didn’t love it as much as A Study in Drowning.

Thank you to HarperCollins Children's Books for an early review copy.

Ava Reid's latest book is a direct sequel to "A Study in Drowning" and follows Effy and Preston after the events of the first book. While this book takes a much more subtle approach to storytelling, Ava Reid manages to pull of a good follow-up and an entertaining story filled with great mental health representation and societal commentary.

I was pleasantly surprised to discover that A Study in Drowning had a sequel, and A Theory of Dreaming delivered a fun and immersive reading experience. Ava Reid continues to weave her signature gothic atmosphere and lyrical prose, drawing readers deeper into a world shaped by myth, memory, and mystery.

While I didn’t love it quite as much as the first book, it still stood strong as a follow-up. The emotional stakes were engaging, and the evolution of the characters felt meaningful. Reid expands on the world in interesting ways, offering new layers to the lore and themes introduced in the first novel.

Overall, a solid sequel that deepens the story in satisfying ways. Fans of A Study in Drowning will likely enjoy the continuation—just don’t expect it to outshine the original.

This is Ava Reid’s follow up to the emotional and atmospheric YA fantasy A Study in Drowning.

I absolutely adored the first book, so I was thrilled to receive a digital arc.

This was an interesting sequel for me. It focuses more on Preston instead of Effy. We saw so much character growth in Effy in A Study in Drowning – I wept for her in that book and was so thrilled at her choices and the power that she took back for herself.

So in some ways, I kind of wanted the story to stop there for her, not to see her experience more challenges in this book. And there are plenty of more challenges – she’s still living in a patriarchal society, amidst the same students who shamed and shunned her before, and struggling with her mental health. Everything wasn’t fixed by her actions in the first book.

The result is a story that’s painful, emotional and even haunting. Preston takes a more central role in the plot, and his story is beautifully told. But we get plenty of Effy as well.

I love how Ava wrapped up the story and teared up at the beautiful conclusion. I just don’t think this one had quite the same emotional impact as the first, probably because my expectations were too high. I still highly recommend this duology to any fantasy reader!

There’s a quiet, aching beauty to A Theory of Dreaming that really worked for me. Ava Reid’s writing is beautifully lyrical (as usual), and I loved returning to Effy and Preston’s world.

The middle leans introspective, with more focus on emotion and theme than forward movement - but there’s something so compelling about it. It felt like wandering through a fog of memory and grief, and while I craved a bit more plot at times, I still appreciated how carefully it all unfolded. Reid did a fantastic job at conveying the atmospheric, dreamy tones.

But even with that slower pace, this is a beautifully written exploration of grief, identity, and the cost of holding onto love. The emotion is subtle but steady, and the final chapters brought it all together in a way that really worked and ended beautifully. I definitely recommend reading this one if you loved A Study in Drowning and are craving another thoughtful, intensely emotional, atmospheric read!

I absolutely loved A Study in Drowning, and was so happy to be able to return to that world and characters in A Theory of Dreaming. I did enjoy this book, but not quite as much as ASiD. While it was interesting to have Preston's point of view since we only saw things in Effy's perspective in the first book, I felt that his character development was lacking. Nothing really seemed to change in his relationship with Effy throughout the story nor did his viewpoint on wishing to protect her. I really didn't like how he kept a lot of secrets from her, and while Effy would do the same, she was more likely to come clean than Preston. What stood out to me the most in this book was the mental struggles that Effy was facing and have realistic it felt. We got to see that in the first book, but with what occurs towards the end of this one, I felt that we really got to see how close Effy was to giving in to her thoughts. I honestly wish we got to see more of her perspective during that point in the book to get an even better emotional feel of her thoughts during that point. I feel like not very many books tap into mental health and depression like these books have, and I feel like this is done so well even though this is still a fantasy book. There were still some questions I had by the end of the book mostly about the dreaming world as well as its connections with Angharad and Antonia Ardor, but maybe it is supposed to be open-ended or I missed something. I did enjoy the ending and felt that it concluded very nicely with everything pretty much coming to a close.

A Theory of Dreaming is the epic finale in the A Study in Drowning duology and follows Preston and Effy as they navigate the consequences from book 1.

Wasting no time, this book starts off where the last book ends. Preston's and Effy's research paper on what they uncovered is ruffling some university feathers. With the escalating war between Llyr and Argant, many feel it is not the ideal time to unveil something that may not fit their nationalist narrative. But some in the college are still seeking answers into their past, recruiting Preston to help in the endeavor. Then there are the elusive bells, ringing in his ears. All the while, Effy is dealing with new policies and professors that seem to have it out for her. Can they drown out the noise and prevent one another from drowning again?

This book is dual narration, giving us a look into what make Preston tick. I absolutely loved this book. While it's a tad slower paced than its predecessor, it is equal in storytelling. Ava Reid is just masterful at creating these gothic mysteries and weaving in fantasy and romance. It was engaging, and sometimes enraging with how many of the aspects Preston's and Effy's experiences mirror issues today. The prose is so absolutely beautiful and eloquent. Once again this series had me tearing up from heartbreaks and triumphs. Preston and Effy are just so pure and I adore how he adores her.

A Theory in Dreaming is a worthy finale and a satisfying conclusion to a fantastic duology that I can't wait to read again.

Thank you to NetGalley and HarperCollins for a copy of this ARC.

"A Theory of Dreaming" is a haunting and introspective sequel that delves deeper into the lives of Effy and Preston, exploring themes of trauma, identity, and the blurred lines between dreams and reality. Ava Reid's lyrical prose and atmospheric world-building create a richly immersive experience, though the pacing may feel deliberate for some readers. This novel is a contemplative journey into the complexities of the human psyche, offering a poignant continuation for fans of the series.

We pick up almost immediately where we left off in book 1, and we're thrust into a world of academic mistrust, deceit and prejudice. Where previously our protagonists were fighting against the evils of the supernatural world and the ever-crumbling ground beneath their feet, they now face a corrupt institution built on lies, war propaganda and a deep-sleeping magic that we learn more about as the story unfolds.

I loved the new characters we were introduced to in this sequel (Lotto! My sweet, misguided boy!) and further exploration into the poetry/literature of the world was so intriguing, especially so because we were bread crumbed into solving the truths and finding facts hidden in each line of work. Reid's prose continues to impress me as it always leaves me with a story that feels layered and intricate!

"Love whispers. Grief shouts."

The anticipated sequel to A Study in Drowning is finally here!

After I finished ASID, I was left craving more. The world was so enchanting and palpable and I simply wanted to know MORE. Who are the Sleepers? How does their magic work? Why are these two nations at war?

Now we are finally getting more answers as the story expands beyond the limit of a remote Mansion and returns to the centre of the conflict, the University of Llyr. Effy is about to embark on her first true day as a student of the College of Literature and has to proof herself against dismissive students and faculty alike.

Effy and Preston are under immense scrutiny after their shocking revelation back at Hiraeth Manor is published. But we also discover another literary conspiracy rooted in misogyny and academic prejudice only Effy has the courage to investigate. The writing itself is highly lyrical and evocative of the dark winter days and looming threat surrounding the university.

Where the story did not succeed for me, is the fall from grace for Effy. Her character strength from the first book is entirely undermined and leaves her a crumpled shell of her previous self. She seemed to only rely on Preston which took away her previous character strength. Depictions of depression are important but I do not think that the journey (or healing) of her substance addiction was represented well, I did not feel that the change came from herself, making her a passive side character in her own story without contributing to the overall plot.

"Whatever faults I might have - and I have plenty - just know that I think of you, always. My mind is never empty of you. Not in waking; not even in dreaming."

Preston's new storyline was interesting and allowed us to experience the increasing rise of fascism and the oppression of the free media. Overall, the political implications are strong throughout the story and given the current affairs is strikingly accurate and scary at the same time.

Unlike the first book, there is no physical representation of an enemy which can be a little disorienting. There are some antagonistic characters but the overall conflict happens off page.

Thank you to NetGalley and Harper Collins for the digital ARC!

I am a huge fan of ASID and Ava Reid's writing in general, so I was very excited about this sequel. In this book we follow Preston who is haunted by the sounds of the bells in his head and his inability to stop dreaming. Meanwhile, Effy is struggling to establish her place as the first woman in the literature college. They are both combatting their peers' and advisors' disapproval regarding the reveal of Myrddin's deception and theft.

This book did not disappoint in its atmosphere, lush descriptions, and beautiful writing. As always, Ava's writing is so evocative and I really related to both Effy and Preston's struggles in this sequel. As compared to ASID, it is a much more quiet and introspective novel. Although I enjoyed the deep dive into the characters, I do wish there was a little more plot. The beginning and end of this book were very solid, but the middle fell a little flat for me. My favorite parts were the tender moments between Effy and Preston and seeing Preston challenge his beliefs about himself. I really liked how Ava showed that myths and literature can be used as tools to incite hatred and violence. Overall, this was an enjoyable sequel, but I think I prefer A Study in Drowning. 3.25 stars!

A great sequel. I love that we explore the characters more! This is a wonderful, dark world. The imagery and the metaphors are top notch.

Synopsis: What if dreams weren’t just dreams… but doorways?

That premise alone pulled me in, and it only got better from there!

This is the second book in Ava Reid’s dark academia duology, and it absolutely delivers. Effy and Preston are back, and now they’re both scholars dealing with the fallout of everything they’ve survived. The mystery this time? Literary conspiracies, dreamworlds, and academic secrets that don’t want to stay buried.

There’s a lot going on here: trauma, nationalism, and gatekeeping all wrapped into a moody, gothic mystery. But it never feels overwhelming. The atmosphere is rich, the pacing keeps you hooked, and the dreamlike writing style really works for the story being told.

Also… Preston. Absolute standout. His loyalty, his sharp mind, and the way he cares? Amazing. I loved getting more of his POV this time!

If you like dark academia, eerie mysteries, and subtle themes about healing and identity, definitely check this out. I can’t wait to see how everything wraps up!

I wish I could have finished this book, but i saw the suicide attempt in a different spoiler and also, just saw it coming and realized I wouldn't be able to finish this book. For what I read - 5 STARS!

Effy and Preston are back, but this time the danger is real. As she fights to hold onto her future and he begins to lose himself to dreams, their love is tested one final time.

Ava Reid’s writing is so beautiful. Her ability to craft atmospheric settings makes every world she creates feel fully alive. This story leans more toward character development, focusing on the internal experiences of Effy and Preston as they navigate their return to university life. I especially appreciated the nuanced portrayal of mental health through Effy’s perspective. I also thought there were such beautiful moments between Effy and Preston.

What I loved:
- Stunning writing
- Immersive setting
- Thoughtful mental health representation

What didn’t work for me:
- Certain elements felt underdeveloped
- Pacing was too slow at times

Thank you to NetGalley & Harper Collin’s for the ARC

I love Ava Reid’s writing style on the surface level. I loved A Study in Drowning, even though it took me a while to read it.
However, I did not love this book. It felt like I was slogging through water as I read. Unfortunately, this and the subject matter made for a rather depressing experience.

I read A Study in Drowning last year and absolutely loved it. I was not expecting the second book, so that was such a nice surprise for me. One thing is for certain that Ava Reid is an amazing writer. Her prose is beautiful, and the atmosphere of this series is very captivating. A Theory of Dreaming picks up where the first book left off, and the story focuses more on Preston. I loved the dynamic between Preston and Effy in the first book and wished we could see more of that in this one. However, since I really enjoy Preston as a character, I didn’t mind it too much. I adore this series and am sad that it’s come to an end, but I'm excited to read the companion novella. If you like lyrical and beautifully written stories, I highly recommend this series. Thanks to NetGalley and HarperCollins Children's Books for the ARC in exchange for my honest review.

The prose and dreamlike quality of Ava Reid's work continues in the sequel to A Study in Drowning. The story resumes with the events that follow the first book. Dealing with injustice in academia, women in male-dominated fields, prejudices, and war. It's darker overall as it also continues to explore their mental state during everything. We get more of Preston in this book! Which I love, as I wasn't entirely in love with him in book one, as I was more focused on Effy. I loved exploring more of their relationship and the trials they faced together and apart. The book's mystical and magical elements were top tier. I will say that because we get more of Preston, the story can feel disjointed at some points, with the storyline not as linear. Overall, I still love the themes, the prose, and the characters!

A Theory of Dreaming is a wonderful dive back into the world and characters of A Study in Drowning. This time, Effy and Preston are back at school and their groundbreaking thesis isn’t as well accepted as they’d hoped. The war continues to rage, with increased xenophobia and propaganda. This book is a character drive story, without as much action or hard hitting plot. It’s a poignant exploration of mental health and dealing with depression, pressure, and navigating relationships.

“...just know that I think of you, always. My mind is never empty of you. Not in waking; not even in dreaming.”

So much more of Preston and so much yearning, omg. A lot of people felt like this didn't need a sequel and while I do believe book one ended on the perfect note I was also very curious about how our main characters lives would be in the aftermath of what happened.
