The Theory of Uncertain Things
Coralie Taylor didn’t fly all the way from the cold Atlantic coast to Hawai‘i to fall in love. She came to study marine biology, earn her place despite the constant anxiety attacks (everyone has them, right?), and prove her full-ride scholarship wasn’t a mistake. All she's ever wanted was to work in the ocean and become one of the women in STEM she's always admired.
What she didn’t plan for? Holden Wilkes. An undeniably attractive, emotionally unavailable PhD student—so infamously difficult that most people avoid him on instinct. Admired by some. Feared by the rest.
And—because the universe has a sense of humor, it seems—he’s also her TA.
Holden does his best to keep his distance, scowling the second she walks into a room. Coralie tries not to care—though the scientist in her can’t help wanting to figure him out.
But despite their best efforts, their friend groups overlap. And somehow, Holden always ends up where she is—especially when things go sideways. Which they do. A lot.
This careful stalemate unravels when they’re sent to a remote island for a research project.
Far from campus and up against challenges neither of them expected, they’re forced to do the one thing they’ve spent months avoiding: trust each other.

I received an Advanced Reader Copy of this book!💙
This book means everything to me, and I mean EVERYTHING. I have been waiting for a STEM romance novel set in my field for years and this book did not disappoint. I have even DM’d Ali Hazelwood asking for her to write a book just like this. I am so in love with the couple, and even more in love with how Coralie navigates being a woman in STEM and taking up space. I feel so seen within the pages of this book with Coralie’s character, and with how she handles moving across the world for her career. This book is SO important to me and I believe it will also be important for other women learning to navigate their career and being a woman in a place that does not always welcome them.

I picked this book up after Amazon randomly suggested it. I’m so glad I did since I devoured it in just a little over 24 hours.
I loved Madysson’s writing and how she did such an amazing job of incorporating real places and food in Hawaii as well as actual facts about marine life. I found myself looking up pictures and doing my own research while reading.
I really enjoyed both the FMC and MMC in this book, I love a grumpy x sunshine trope. The FMC was relatable and a breath of fresh air and I found the development of their relationship to be natural. The MMC was broody yet still cared in all the right ways.
I will definitely be reading more of Madysson David’s books in the future. This was an amazing debut novel.

Read as a beta reader back in Jan and my reading slump was cured! I found leaving feedback so difficult because I thought it was so amazing. The perfect STEM romance, with the best mix of STEM and romance. Coraline is SO relatable and made me feel so seen. Her work is just as important as her love and you’ll even learn some cool biology facts. Madysson’s writing is spectacular, the imagery and landscapes were insane, I was so jealous the whole time. She’s introduced the most amazing characters, I fell in love with them all, and the found family aspect was so special. I can not recommend The Theory of Uncertain Things enough and I am so excited to read it again🩵
Review of advance copy received from Author
5 stars! I received an advanced copy from the author and couldn’t be happier because this book was such a delight.
Romance, marine bio, and scuba diving all in one book?! say less. The writing was gorgeous and I absolutely looooved how heavily the author leaned into the science involved in this book. The characters were all so fun and I loved the wit and banter between everyone. Would highly recommend to any and all ocean lovers!

I received an ARC of this book… and it was so much better than I was expecting 🥹
I loved the romance, the yearning is on point, the way they kind of orbit around each other in an inevitable way… it’s so beautiful and heartbreaking and I just wanna dive in the book and do something about it! 😂
I loved all the scientific data and I absolutely loved the message about STEM women. Just like Ali Hazelwood, my favourite romance author, the author brought the subject up in a brilliant way. Women can be whatever they want! We are amazing!
My favourite character is definitely Damon. Stole the show 🐙🩵
Madysson David, reading your book reminded me why I wanted to be a marine biologist in the first place and I got to leave a little bit of the dream through Coraline. For that, thank you 🩵

OMG this was such a fun way to kick off my summer reading! I pre-ordered this book as a birthday gift for myself. Loved it, reminds me of Ali Hazelwood's Love Hypothesis in a marine biology setting with a little bit younger generation. The atmosphere and friends were so fun it made me jealous, made me want to visit Hawaii and learn to surf. Which is really saying something because the sun and I are not friends. The insight into STEM was not overwhelming in my opinion, but I love a book that expands my knowledge and makes me go look up new words and cool creatures. No guilt in recommending this to anyone, there is no spice but I didn't miss it (still plenty of romance). I was already highlighting lines in the first chapter. "The highway doesn't impress - has a slab of concrete ever sparked joy in anyone?"(I can't decide between turning this quote into an ironic bumper sticker or tattooing it somewhere on my body) and the Bonus chapter, what a gift! I totally understand if this is a one off but would love to read Theo's story too!

As a women in marine science field I love seeing representation in a romance novel. I loved the concepts and how defining women in stem with their accomplishments and not just forming to a mold!

This book was so good that I had already finished it the first time within 48 hours, then I read it a second time to soak it in more and then read it a third time to make a music playlist for the book.
The way this book just feels like it’s written for me. I feel like I’m part of the story, the emotions, the way emotions are being expressed, the over thinking, the anxiety, the anticipation, the pure nature that the main character, Coralie, is in total awe of. I read A LOT, I have read A LOT of books, I’m always reading a minimum of three books at a time because honestly, I just find home and comfort in books more than other book lovers do(in my selfish opinion), but I have NEVER felt this comfortable, seen, I feel like I’m part of something huge. I spent my whole childhood, and even still now, absolutely dreaming of being a marine biologist, it’s honestly just something I’ve always been passionate about, but instead I became a mom and I feel like reading this book, like I’m there, like those childhood dreams came true, I’m really there living it out.
A Theory of Uncertain Things is honestly very quickly becoming my all time favorite book. Even though the dream of being a marine biologist didn’t happen, I feel like it still happened through reading this absolutely beautiful story and how much I feel as if I was entirely immersed in this world.
So um now, as an extreme book lover, I need like five different versions of special editions and I need this book displayed everywhere in my house.
I think what is also really hitting me is, I am also a very anxious person much like Coralie, I’m in therapy twice a week, and ironically, we started working on my grounding word during panic attacks(peaceful), and the scene that comes to my head with that word is the beach, the ocean, waves crashing, finding seashells, hearing the animals, seeing the wild dolphins, and somehow, even though I have seen all of that in real life a few times, it just hit me on a deeper level, it hit me in a whole new way, a whole new way of comfortability, of calmness.
I’m sorry if all of this is too much or all over the place, but I’m just feeling all of the emotions. From the bottom of my heart, this book really gave me a sense of home, most books place you into a new world, but this one brought me back to my favorite world, my favorite home, the ocean.

STEM FMC: marine biology masters student; STEM MMC: oceanography PhD candidate
Nobody sees you as a woman in STEM quite like another woman in STEM. It doesn’t matter the field of study or where you are in the world, our experiences are much the same. There’s something so comforting about reading a STEM romance written by a STEM girlie. It’s like being wrapped in your favorite blanket while chatting with your besties about life, love, and science. There are so few true STEM romances out there where the science takes center stage, and while Ali Hazelwood is everyone’s go-to STEM romance author, I absolutely love finding more options. That being said, if you enjoyed The Love Hypothesis, you need to give this one a shot: it’s got a stem academia setting, teacher/student dynamic, grumpy sunshine, he hates chocolate but always has a chocolate protein bar on hand for her because she forgets to feed herself, and a sloooowww burn.
If you like STEM romances, you need to have this one on your list! This book was well written, the character arcs were excellent, and there's a cute little octopus. If you’re looking for spice, this isn’t it, it’s kisses only, but I don’t think the romance suffered for it. As a personal preference, I do wish we would have gotten at least to closed door, but it didn’t affect my rating.

Five stars ⭐️⭐️⭐️⭐️⭐️Are we sure Ali Hazelwood isn’t writing an under another pen name???? Madysson David = Ali Hazelwood??? This STEM romance is on par with Love Hypothesis ❤️ I cannot believe this book is a debut novel from an indie author! I absolutely loved it!!! It was written with so much passion and intelligence ❤️❤️❤️ The book was funny & witty. One of my favorite things about this book is the characters were adults and ACTED MATURE!!! The FMC had clear communication and expected it back. I loved the Hawaii vibes. I loved the ocean science interwoven into the story. If you like a smart romance, mature characters, lots of yearning (the yearning was 🥵🥵🥵) ocean vibes, college setting, you will LOVE this book! The tension and yearning was absolutely 5 stars - literally perfect - no notes! My only tiny critique is that there was not even a fade to black, but I totally understand that not everyone likes to write spice. The writing was thought provoking and downright brilliant! This was absolutely 5 stars! If you are looking for a no spice STEM romance, this will be your FAVORITE read of the year!

My thoughts:
I was really excited for this book and tried really hard to love it, but it just wasn’t the book for me.
I liked Holden and Coralie. They were sweet. Holden was honestly the best part of this book. He was so caring and the literal definition of a gentleman. The way he asked if he could touch her every time was so sweet! Every. Single. Time. I also loved how he called her “Trouble”.
There were some themes I personally didn’t agree with, specifically evolution. But that’s just my personal preference.
The romance fell kinda flat to me, but Holden’s bonus chapter made it better. I was just hoping for a little more in the romance department.
I would recommend this book if you like: marine biology, STEM romance, Ali Hazelwood’s books (I haven’t read any, that’s just what other readers are saying) or a summer vibes book set in Hawaii 🫶🏻
Tropes:
🪸STEM romance
🪸he falls first and harder
🪸grumpy x sunshine
🪸forced proximity
🪸TA x marine biology student
🪸slow burn
🪸found family
Content:
- 3.5☆
- spice: kissing only
- language: 39 swear words. 15 f-words. 17 uses of Lord’s name in vain.
- TW: grief

This was a surprise. I haven’t heard much about this book so didn’t know what I was getting into. Is it weird that my favorite parts were having to do with marine biology? The science was so interesting and incorporated seamlessly into the story. The FMC’s research with octopuses was super interesting and this book didn’t only partially explain the science and only focus on the romance, without the story being boring and bogged down by it.
I also liked the forbidden romance aspect of this - he’s her TA. I thought there were several forced proximity / classic rom com moments (he takes care of her, rescues her) etc that I enjoyed.
I loved the Hawaiian / ocean setting and mostly enjoyed the romance despite the constant back and forth / hot and cold MMC. I also double loved that it was single POV! I do not always need to know what the MMC is thinking all the time. Definitely a great summer read and I recommend it.

3.5 ⭐
Despite the description, I didn't expect so much marine biology talk. The descriptions also took me out of the story, I had to skip multiple paragraphs sometimes. I did love the segments involving Damon though.
The world has moved past the need for emotionally constipated MMCs. It was very obvious why he was avoiding Coralie, all he just needed to say was why instead of asking like a highschool boy.
The ending seemed rushed. I would have liked to see more development in their relationship

Absolutely beautiful book. I love a good STEM romance and this was exactly what I was looking for. As someone who loves most of Ali Hazelwoods books dare I say this one replaced The Love Hypothesis from the podium…
It definitely has a lot more STEM talk (specifically marine science and damon ikyky). Coralie is such a quirky character that you’ll love. HIGHLY recommended.

Review of advance copy received from Author
I had the honor to read the "Theory of Uncertain Things" as a betareader back in January. I haven't been able to forget it ever since and it will always have a special place in my heart. As a biological oceanographer, I wish I had read it younger, when marine science was something that seemed out of reach, I am glad to have read it with the experience I have now and I know that I will reread many times as I get older, trying to relive the feelings. Mady manages to capture authentically the experience of studying marine science, in a way that you almost think you are reading your own diary.
The plot of the book revolves both around the science and the romance.
I think I have to clarify that the book isn’t addressed just to people that exist in marine science one way or another or that the simply love the ocean, this book is for everyone. Well maybe not for the people that do not like a slow burn. Even if you do not know anything about the ocean you won’t have trouble with the setting, terminology etc. If you want to learn a thing or two you will, but if you won’t you will not be overwhelmed or intimidated with irrelevant information that takes you out of the story.
About the romance, they are a slow burn couple, with chemistry that you rarely find in book. The FMC is one of the most relatable characters I’ve ever read, I can’t count the times I was saying “that is so me” while reading it, she is shy, pleasant, clever, not a know it all kind of person, loves the ocean and is ready to befriend any marine creature. The MMC is a grumpy, green flag, protective, loving guy that you will fall for, and not for how hot he is but for everything else. Together they make a pair that is pure pleasure, you will not be able to stop melting, giggling, keecking your feet in every chapter and with details of this book are *chef’s kiss*. The characters are funny, each with their own personality that complete the story and bring it together, they have great vibes and I would like them to be my friends too.
The writing style is fresh, easy to follow with perfect pace and it took me less than 2 days to finish it, I can't wait to read the final version and fall in love again.

Review of advance copy received from Author
The Theory of Uncertain Things had me at marine biology in Hawai‘i, but it kept me with Coralie-anxious, ambitious, and trying so hard to prove she belongs in a world she has dreamed of entering.
There’s something really tender about a heroine who wants something so badly, not because it looks impressive, but because it feels like part of who she is. Coralie’s dream of working in the ocean and becoming one of the women in STEM she has always admired made her so easy to root for. Her anxiety adds a quiet emotional weight to the story, especially because she’s not just fighting for a future-she’s also fighting the fear that maybe she has to constantly prove she deserves it.
And then there’s Holden. Emotionally unavailable, difficult, admired by some, feared by others, and somehow also her TA. Truly, the universe saw Coralie trying to focus on her scholarship and said: what if we made academia emotionally inconvenient?
What I liked most was the tension between them. Coralie tries not to care, Holden tries to keep his distance, and yet their worlds keep overlapping. There’s a lovely kind of push-and-pull in that setup-not overly loud, but quietly charged. The scientist in her wanting to figure him out was such a clever touch, because honestly, complicated men are not research projects… but romance heroines remain brave in the name of discovery.
The remote island research project gives the story a strong emotional turn without needing to be overly dramatic. It forces them into the one thing both have been avoiding: trust. And I loved that idea-because sometimes romance isn’t about instant softness or perfect timing. Sometimes it’s about slowly realizing the person you didn’t plan for might be the one person you can rely on.
Overall, this was atmospheric, thoughtful, and quietly romantic. A beautiful choice for readers who love STEM heroines, difficult love interests, forced proximity, and stories where feelings arrive with absolutely no respect for logic.

I beta read this book back in January and I can't stop thinking about it since.
I loved following Coralie as she embarks on a new aventure in Hawai'i away from her small town in Canada and how she fight to fulfil her dreams. She faces challenges of a woman in STEM, but she never gives up or let herself be intimated by what's being said she knows her worth and I loved that for her. I also loved the friendships she developped during the story and how they're never treated as second best compared to the romance, the friend group is important and here to stay.
It is as much a story about her and her challenges as a romance.
The romance is so swoon worthy I can't forget their cute moments, it's sweet and touching and challenging, it's about them trusting each other and I loved it. It's full of tension and heavy glances but also really sweet moments. It's a slow burn made of teasing, lab experiments and forced proximity and a shared passion and it was so beautiful.
Overall as someone who loved the ocean for as long as I could rememeber it's a novel that's gonna stick with me. I've always wanted to read about characters that feels like me and Coralie would probably be my best friend if we met in real life. The ocean, marine science and all kind of critters are as much an important character as Coralie and Holden. I loved exploring these places with them, reading about the sciency things and be transported in this story.
When I finished this book it gave me a strange feeling of peace and hope and determination, Coralie is an inspiring character and the author writing style just made her so real to me.
I cannot wait to read it once more when it's out in a few weeks.

When I finished this book it gave me a strange feeling of peace and hope and determination, Coralie is an inspiring character and the author writing style just made her so real to me.
I cannot wait to read it once more when it's out in a few weeks.

Coralie Taylor is an aspiring Marine Biologist who came all the way to Hawai'i from the Atlantic coast on a full scholarship ride. She is here to study, prove her worth and become one of the women in STEM she has always admired. She's definitely not here to fall in love, right? (.....right?).
Enter Holden Wilkes, the attractive, emotionally unavailable yet remarkably bright TA (who always smells like pine somehow). Even though Holden tries to avoid her at all costs, Coralie is determined to know why he does this. And she finally gets a chance to do so, when they are sent on an island for a research project.
What I loved about this book was that it actually made me learn new things about Cephalopods and Marine Science. I also loved how this book was pro 'Women in STEM' and how it portrayed real life situations that women at certain positions have to face at workplace through deep and well written dialogues.
You could actually relate with the FMC, and love her nature and determination to advance in her field. I also wanna give a shout-out to her amazing friends, specially Theo and Maya who made her feel comfortable in a new place and always supported her. The slow burn in the book, the small incidents would leave you asking for more. The unsaid tension between her and Holden is something you wouldn’t wanna miss. Overall I felt it was a good summer read for me.

The Theory of Uncertain Things is a beautiful, comforting STEM romance and I absolutely adore it. The story follows marine biologist Coralie as she arrives in Hawai‘i to chase her dreams in STEM. She has to navigate anxiety, belonging, research chaos, and a very emotionally inconvenient attraction to her TA, Holden. The writing had me hooked from the beginning, with vivid descriptions of the ocean and scenery, and the way the science felt naturally woven into the story. You can tell this was written by someone who genuinely loves marine science. It made every lab scene, field project, and random ocean creature feel fascinating instead of overwhelming.
Coralie is such a relatable FMC. She's determined, awkward, passionate, and incredibly easy to root for. I had multiple "this is me" moments as I was reading. And Holden absolutely stole my heart with his quiet, grumpy-but-soft energy. He's a green flag MMC in the best way! Their relationship is a perfect slow burn yearning kind of romance and I loved it!
What really made this book special for me was how balanced everything feels. The romance is adorable and full of chemistry, tension, teasing and heavy glances, but the friendships and found family moments are just as important. All the characters feel real and lovable, and the story never loses sight of Coralie’s personal journey alongside the romance. Marine biology, island research trips, and one very adorable octopus make for an absolutely winning combination in this STEM romance. It's such a sweet, addictive read. I read it in one day, then reread it and I already know I’ll be reading it again in the future🌺🌊🐙

Marine Biology Romance 🌊🐠🪸🐙
ARC REVIEW:
This book was absolutely incredible!! I ADORED every part of it - the romance, the science, the marine creatures.
The characters are so easy to fall in love with, and from the very first chapter, it becomes so easy to form a connection to each one of them. I loved Coralie as the main character, and she honestly felt SO relatable in all the best ways. And Holden… Holden was EVERYTHING 🤭
This book is PERECT for fans of The Love Hypothesis. Think academia setting, women in STEM, and student x professor/TA. And this wasn’t just regular science, but marine science. There were so many facts woven throughout the novel, and I found everything so intriguing! The best bit, by far, was all the little marine creatures we got to learn so much about - special mention to Damon, the little octopus (cephalopod!) we spent a lot of time with!
Could not recommend this book highly enough!!
Thank you so much to the author for giving me the opportunity to ARC read this amazing novel 🤍

The Theory of Uncertain Things is definitely a comfort book 🙂↕️💞
I got to beta read this back in February and it was such a delight I had to dust off my ancient Goodreads to review it properly! Such a cute read, I’ve been dying to talk about it for months!!!! I squealed so many times!
Madysson’s writing style is so immersive that the very first paragraph had me hooked. Once I started reading, I could barely put it down. I can’t wait to get my hands on a physical copy and re-read over and over. Everyone in my life has heard me obsess for a while now.
Not only is the romance aspect adorable, but the friend group is so built-out and specific that it’s almost like I knew them as well. AND the marine biology romance book is written by an actual marine biologist?? Women in STEM, writing about their fields of expertise???? I’m sat. 🐙🦈🤿

I was lucky enough to receive the advanced reader copy of this book and I am so grateful.
I was hooked right away! The writing is incredible. The perfect amount of detail and description. It makes you feel like you’re part of the story. Like you’re in the landscape and really feeling the emotions all the way through.
The setting is amazing. The romance is everything (and I mean EVERYTHING). But equally as incredible are the friendships and the story about Coralie and her research/ finding her place in the field. The characters feel so real, human, and relatable.
I felt seen. I learnt things. I felt so many emotions. It gave me everything I want and more.
This book has become an instant favourite for me and one I will go back to over and over again.

I had the fortune of getting to read this as a beta reader. It's perfect for fans of Ali Hazelwood and stem romances. I've felt like the marine world has been missing romance books. Love the work Madysson :)
P.S. Damon the octopus is the cutest little guy!

I really enjoyed this book! I love a STEM romance, and this delivered everything I expected and was hoping for. I feel like I learned actual scientific facts as I read. I don’t trust in evolution, and this did lean into that throughout the book, but besides that it was amazing! The MMC is super hot, totally likable (even when he seems like a grump) and he made me so giddy! I ate this book up.
No spice, some strong swearing.

Had the absolute pleasure of beta-reading this book!!
This book got me out of a complete reading slump earlier this year and I’m eternally grateful🙏 It was a joy to read, from the fantastic location descriptions, to the fresh writing, to the dynamic characters. I totally fell in love with our main characters, Holden and Coralie have my heart💙 It was a refreshing romance, with the relationship between our two leads intermixing with academic uncertainty, complicated feelings of belonging in a new place, and research pursuits.
Would highly recommend and I CANT WAIT to read the final version, and anything else this author publishes in the future!!🌊🐙
