The Love Hypothesis was the first rom-com trope book I ever read, and I loved it!
The Love Hypothesis was the first rom-com trope book I ever read, and I loved it! From the very first pages, the story had such a captivating feel and vibe. The dynamics between Olive and Adam felt smooth and engaging, almost like Cheers in a science lab. I adore that unique atmosphere throughout the story. The side characters were also fantastic and humour-filled, which complemented Ali Hazelwood's superb writing. It was such an easy read that drew me in completely. I will check out more of the author's talented works and highly recommend this as a must-read!

Grumpy-meets-sunshine romance with flawless banter and wholly loveable characters.
Our main character Olive is a third-year Ph.D. candidate, pumpkin latte obsessed and one of the most fun characters I’ve read about (and got to know even greater as the book went on) in a very long time. At the beginning, she’s desperately trying to convince her best friend Anh that she’s dating someone so that Anh will finally take the plunge and date a guy that Olive isn’t interested in (although Anh thought so, which is why she wouldn’t go for it.) The first guy that Olive finds on campus is Adam Carlsen. Tall, brooding and a widely-known pain in the butt, he’s a young professor that’s very well known for being anything but kind. She kisses him when she knows Anh will see, sealing her fate. But she’s shocked to discover that Adam has his own reasons for wanting a fake romance, and before she knows it, they’re embroiled in a romantic façade over coffee dates, embarrassing scenarios and line-crossing moments. Olive can’t deny that she’s falling for Adam. Once thought to only be an idiot in general, she starts to see something brighter beneath the surface. The more that they find themselves turning their fake romance into a real connection, the harder it is to see the finish line coming up where they’ll both no longer need to hide behind the false narrative they began. But after a science conference throws Olive into a traumatic frenzy – and she crosses the line firmly with Adam, too – things go from zero to one hundred in the blink of an eye, throwing both of their fates up in the air in the follow-up. Overall, The Love Hypothesis threw me. I’m usually not a fan of third-person POV, but somehow I managed to gel with Olive’s character immediately. I completely adored the subtle, yet powerful romance between her and Adam, and his character was equally as *chef’s kiss*. I loved that there was so much girls-supporting-girls, representation and no cliff-hangers, leaving everything in a place that made my heart happy. It was truly what I can only describe as a grumpy-meets-sunshine romance with flawless banter and wholly loveable characters, with a little extra spice thrown in. Five massive stars!

Funny academic romance
This was my first read by Ali Hazelwood and I rather enjoyed it. Although is it an academic romance it has a wide appeal to all. So the premise of the book is PHD candidate Olive in order to convince her best friend Anh that she should date Jeremy, Olive’s ex who Anh really likes (btw I personally think this sucks as who dates their best friends ex?). In order to convince Anh that she is dating and is over Jeremy, Olive kisses the first man she see, Dr Adam Carlson - the well known grump of the biology department and secret admirer of Olive. Both for various different reasons agree to enter into a fake relationship. This book falls into the Academic genre of romance with strong grumpy/sunshine vibes, Olive was so endearing and sweet and I enjoyed watching her open up to Adam as he surprises her by offering her his unwavering support. Adam shows Olive nothing but kindness and his unwavering support while she goes through various up and downs and in turn Olive I think rather brings out the best in Adam. The confrontation near the end when Adam comes to Olive’s defense was enough to make a women swoon. If you like sweet, endearing but determined realistic FFM’s and brooding, grumpy but kind and loving MMC’s set in an academic world, then you will thoroughly enjoy this book and I would not hesitate to recommend it to you.

Perfection
Honestly, you can inject the fake dating trope into my veins, I love it so much. And this book is fake dating PERFECTION! When Olive ends up kissing Dr Adam Carlson in the middle of the laboratory one evening, she has to quickly explain herself. This revolves into Olive and Adam agreeing to enter a fake relationship - so she can convince her best friend to date a guy that technically is Olive's ex, and so Adam can prove to his supervisors he's not a flight risk for the college, and should receive the grant money they are holding out on him. I really loved this relationship a lot - I thought the dynamic and chemistry between Adam and Olive was so vibrant on page, and it genuinely felt like they were just so happy being around each other. They complimented each other so well, and I just looked forward to every scene that saw them interact, especially if it involved any touching because hot, damn! I fell for Adam's character completely - what an absolute cutie and please where are these guys in real life because I'm free on Friday. I liked how nothing Adam and Olive did was in anyway comprising to their individuals careers as scientists, and this was stated from the start. While Adam earned more money than Olive, and was a bit older, I didn't really feel like there was huge power dynamic in the relationship - it really felt more so that Olive was calling the shots and Adam was happy to go along. I did enjoy the sex scenes though there was a point where I thought some of the descriptions were odd (not sure I needed to know about all her folds) - and I really liked at the start of the book that Olive comes out as demisexual, and it feels like many characters in this were bisexual. I am for it being totally okay for a woman to be experienced in the bedroom and know what she likes - I do think in some romances there is the tendency that the man should teach the shy virginal woman, and while this wasn't quite the case for Adam and Olive, I would have been happy for her to be a bit more masterful/confident in bed with him. I liked how everything worked out and how the conflict was solved in this - and also that the conflict didn't go on for too long. And I feel like I'd be happy to just read about Adam and Olive's relationship forever to be quite honest. Love them.

Cute but overrated
Olive, a 3rd year PHD candidate accidentally but not really accidentally kisses the extremely grumpy professor Adam Carlsen without him having time to react. Okkkk so Olive didn't plan it, but when her bestie Ahn shows feelings for Olive's ex Jeremy, Olive doesn't want Ahn to feel like she can't date him. So what better way to prove to Ahn that she has moved on, than by kissing the first guy she sees in the corridor. And then, even better Adam agrees to fake dating, just until Ahn and Jeremy get together and believe that Olive has moved on. But come on Olive, we all know what fake dating leads to... don't we! Ok ok ok, so was The Love Hypothesis a new favourite? Sadly not. I found the first 11 chapters a bit of a slog to be quite honest. The fake PDA moments made me cringe and also, I have a burning question - why did Olive keep expecting Adam to buy her coffees? I didn't get that at all. So yeah over half was a bit meh for me, I didn't understand the hype at all. Its no spoiler the route this book was going to take, lets be honest. So when the inevitable happened.... well Ali Hazelwood can write a good smutty scene, let me tell you! When feelings were finally revealed, I ended up enjoying this book a lot more. I found both characters likeable (had a bit of a crush on Adam tbh) and enjoyed their chemistry. It wasn't a new favourite and took a while to get going, yet in the end I did enjoy it buuuuuuuuuuuut (and I'm sorry) I think it has been overhyped. Like it was ok, however I have read much better romances.

The Love Hypothesis is an avalanche of serotonin—@thatshortwriter on IG
🇬🇧 Usually I don't like hyped books, but this time I'm super happy to have followed the crowd, because it made me discover a debut book that I loved from the first lines and that has become one of my new favorite comfort books. In all honesty, if I could give it a thousand stars out of 5 I would. The Love Hypothesis is an avalanche of serotonin. It's fun, adorable, awkward and thoughtful. Olive ("like the tree") is a P.h.D. candidate looking for funds for a cancer research and is a young woman who would do anything to see her friends happy—including pretending to be dating the most tyrannical professor on campus (pfff ADAM IS AN ADORABLE MUFFIN) to help her best friend come forward with her ex, guilt-free. And if this also means convincing the University that Adam has no intention of transferring and not losing his funds, it's even better, right? He certainly doesn't accept it for any other reasons. Nope. Read it if you like: - fake dating trope; - grumpy x sunshine; - pumpkin spice latte (wink wink); - university setting; - WOMEN IN STEM; - 🔥🔥🔥 (But even if you don't. Read it. C'mooon!) 🇮🇹 Di solito ho sempre qualche problema a farmi piacere libri (o film e serie tv) super pubblicizzati; ma questa volta sono stra-felice di aver seguito la massa, perché mi ha fatto scoprire un libro di debutto che ho adorato dalle prime righe e che è diventato uno dei miei nuovi libri copertina preferiti. In tutta onestà, se potessi dargli mille stelle su 5 l'avrei già fatto. The Love Hypothesis è una valanga di serotonina. È divertente, adorabile, imbarazzante e riflessivo. La protagonista, Olive, è una ricercatrice che sta cercando fondi per uno studio sul cancro ed è una giovane donna che farebbe di tutto pur di vedere i suoi amici felici—compreso far finta di essere la compagna del professore più tiranno del campus (pfff ADAM È UN ADORABILE MUFFIN) per aiutare la migliore amica a farsi avanti con un suo ex, senza sensi di colpa. Se poi questo significa anche convincere l'Università che il Prof. non ha nessuna intenzione di trasferirsi e non perdere gli incentivi è anche meglio, no? Non accetta certo per altri motivi. Nooope. Leggetelo se vi piacciono: - fake dating trope; - grumpy x sunshine; - pumpkin spice latte (wink wink); - ambientazione universitaria; - SCIENZIATE; - 🔥🔥🔥 (Ma anche se non vi piacciono. Davvero. Leggetelo. Daaai!)

STEM Love story
I devoured The Love Hypothesis—I finished it in two days, which says everything about how hooked I was. This is such a fun, addictive read. Olive is honestly an absolute ding dong at times, but I loved her for it. She’s awkward, chaotic, and so easy to root for, which made the story even more enjoyable. The romance is a proper slow burn, which I really appreciated. It builds up so well, and even though the spice is minimal, it doesn’t feel like anything is missing—the tension and emotional payoff are more than enough. What really stood out, though, is how well the STEM setting is written. Ali Hazelwood does such a great job of highlighting the challenges women face in academia. It’s woven naturally into the story, but it also reflects a very real and, honestly, sad reality. Overall, this book is the perfect mix of romance, humour, and substance. Light enough to binge, but with enough depth to leave an impression

Book review
The Love Hypothesis by Ali Hazelwood ⭐️⭐️⭐️⭐️⭐️ This book was basically everything I want from a light, fun romance. 🥹💗 Fake dating, academic rivals, a ridiculously tall and grumpy MMC, a sunshine-y FMC, workplace tension and SO much banter? Sign me up. Olive and Adam completely won me over. Their chemistry was adorable, and I loved watching their fake relationship slowly turn into something much more real. Adam’s grumpy exterior + the tiny moments where his softer side comes out? 🫠 And Olive is such a lovable, chaotic mess that I couldn't help rooting for her. I also really enjoyed the academic setting. It gave the romance something extra and made the whole story feel different from a typical contemporary romance. The humour and awkward situations kept me entertained throughout, and there were so many moments that genuinely made me smile. Is it predictable? Absolutely. Did I care? Not even a little. 😂 Sometimes you don't pick up a romance for complicated plot twists—you pick it up because you want to fall in love alongside the characters, laugh at their ridiculousness, and leave the book with a stupidly happy smile. A comfort read, a fun romance, and five stars from me. 💗📚
