I wasn’t expecting to fall in love with Marie Curie. But I can’t resist a one-sided crush trope any more than I can resist the brilliance of women making breakthroughs in science. Because I had already read and enjoyed “The Love Hypothesis,” I knew I would most likely enjoy “Love on the Brain” too, but I didn’t expect to learn so much about science and scientific history too. If anything, this book indulges in the delightful nerdiness even more than Love Hypothesis. There is an abundance of charm even as Hazelwood captures the misogyny in STEM fields that at times give this story darker moments. Fans of “The Love Hypothesis,” come for the STEM romance, stay for the cat loving avoidant Marie Curie fangirl scientist bad ass, Bee.

Ali Hazelwood truly has my whole heart at this point! Love on the Brain was even better than I thought it was going to be. The plot, the writing, THE CHARACTERS!! Everything was perfect. And this book just solidifies that Ali will be an automatic read for me till the end of time. I could go on and on but I must stop myself before I spoil the whole thing! Thank you to NetGalley and Berkley for the eARC!

A neuroscientist gets a lead job on a project for NASA, except her nemesis is the other lead. Except, that had very few exchanges, and the one she holds most against him, and thinks he is a jerk for, is a listened through the door misunderstanding. And he has been pining after her for years, there is absolutely noone else. Misunderstandings and then the lies start coming. No, for a book trying to erase stereotypes about women in STEM positions, I wish the author did a little more to erase stereotypes about romance novels.

I requested this title because I adore The Love Hypothesis. While Love on the Brain is a lot like Love Hypothesis with the scientific banter and missed opportunities for communication, it wasn’t as compelling. Bee could have been such a strong advocate for woman in STEM but was constantly ruminating over why Levi despised her and then let him lead rather than co-lead in meetings. All in all, I enjoyed this title but was looking for the magic as in Love Hypotheses. Needless to say, I will definitely read more from Hazelwood because the scientific jargon and Big Bang-like quips are my jam.

In True Ali Hazelwood fashion, this book blew me away. I read it in one sitting and couldn’t stop thinking about it for a few days. It goes without saying that anyone who loved The Love Hypothesis would equally love Love on the Brain. This will certainly be on of my top books of 2022 and I cannot wait to purchase a copy on release day!

As always, Hazelwood's writing is a breath of fresh air in the shit storm that we're all living through right now. Bee is witty, hilarious, and easy to love, but I've got to say that Rocio is where it's at. *insert heart eyes here* Honestly, you could have written a book solely based on their work relationship/friendship and I would devour that in a hot second.

I read this book shortly after reading The Love Hypothesis, which I am OBSESSED with. I know that it's hard to have your next book follow something already so perfect and I feel like that could have happened here, except I didn't like Levi all that much. I felt myself failing to understand his actions towards Bee even when he explains them later on and found the six-year-long secret of his feelings for Bee to be almost unbelievable, especially after Tim made him think that he practically disgusted her. I don't know - I am really nitpicky about my enemies-to-lovers stories, and I didn't really ship these two like I did Olive and Adam.

That's not to say that the writing wasn't great because it certainly is. I just wasn't feeling the main relationship. Rocio's dark humor and witty banter as well as the STEM female empowerment theme was the real hit here.

I will start by saying I really loved The Love Hypothesis, I pretty much read the whole book in one sitting. When I saw Ali Hazelwood had a second in the series I was beyond excited. Unfortunately Love on the Brain didn’t hit the mark as much for me. I am giving it three stars as I generally enjoyed the book but I wasn’t a huge fan of the main character Dr. Bee Königswasser. She was an intelligent scientist working for NASA but I felt like there was a bit of missed opportunity in her being more of a strong female lead. I am a huge fan of the “enemies to lovers” trope in romance books and I was left wanting more romance between Levi and Bee. One more thing I will add is that the ending was a little too much. All in all, I did enjoy the book and am grateful for the opportunity to read it early. I will continue to be a fan of Ali Hazelwood and read anything she writes and I thoroughly enjoyed all of the pop culture references

Thank you so much PRH International for my free copy of Love on the Brain!

I was a bit nervous going in to this book because of how much I loved The Love Hypothesis, and I was scared that this might not have lived up to my expectations. But I have to say, Ali Hazelwood did so well with this one too, she exceeded my expectations! She definitely writes one of the best enemies to lovers trope, grump/sunshine trope, and I love the banters, friendships, and romance.

Ali Hazelwood also never fails to make me love her main characters! Bee was so freaking hilarious and adorable, from the moment I read the first chapter I knew I was going to love this girl. I absolutely loved her personality and her outlook in life, and I love that she is in the neuroscience field (This made me instantly love her because I'm a medical student aspiring to be a neurosurgeon haha).

And then we have our engineer Levi, who I actually found to be so rude in the beginning of the story! But wow, when I found out the explanations for everything that happened I started really appreciating and loving him more. I'm a sucker for a grumpy hero who is such a soft loving man when it comes to the woman he loves, and Levi did not disappoint at all. I love how supportive, caring, and attentive he is towards Bee and other important people in his life.

Their romance was so well done, they went from enemies to friends to lovers. It was so beautifully written, I love seeing them finally let go and open up to each other. They were so freaking adorable together, they were always bantering, teasing with one another but at the end of the day, you could see how much they admire each other. And their chemistry??? It was amazing, there was definitely more steamy scenes here compared to The Love Hypothesis and I am definitely one to complain!

Besides the romance, I really enjoyed the storyline of this one because it was intriguing and captivating. You will start the book with so many questions running in your mind, and once you find the answers it felt really great and might have you screaming a little bit. I also did not expect the plot twist, it angered and frustrated me but it was so well done!

I JUST LOVE THIS BOOK AND I AM READY TO SHOVE IT TO ANYONE'S FACE

Hello! Nice to meet y'all. I'm Erin and I'm formally submitting my application to be Ali Hazelwood's biggest fan.

I love this. I love Bee. I love Levi. I love science and NASA and hummingbirds. I love it when books make me feel this way. I also just want to say that this is my most anticipated book of the year, and OH BOY did it live up to the hype. This was everything I could have ever wanted it to be and more.

I don't want to say too much about the plot because everyone deserves to be as blissfully unaware as I was when I went into it. All I'll say is I've never been a fan of enemies to lovers until now, and now I don't think I'll ever get enough of it. I can't wait until I talk specifics when this is out. Ooooooh my god I will not stop screaming.

***Thanks to the publisher and Netgalley for providing me with a digital copy of this book in exchange for an honest review***
Ali Hazelwood does it again!! She makes STEM chicks cool and grumpy smart men extra hot. I loved the quirkiness of her characters and the romance is always so steamy.

At this point, I would read Ali Hazelwood’s grocery list. I read no— devoured the love hypothesis when it came out and was left salivating, Love on the brain was no different. I was, in no certain terms, obsessed.
In the start I wasn’t sure, I liked it but I wasn’t in LOVE with it. but,
by the 80th-ish page? I would have died for any single crumb of this book.
Love on the brain is a steamy stem-centric feminist romance with all the tropes in the very best way. (Perceived) enemies to lovers? check. he falls first? major check. Grumpy sunshine, where our female lead is the one not so willing to jump in? Check.
Our heroine, Bee is a strong, fun, intelligent-scientist who just wants to better the world with her work and find stability for herself.
Our hero, Levi is a quiet, charming, and seemingly the grumpiest grump of them all, at least to Bee.
but, are things ever what they seem?
HEA guaranteed, steam off the charts. secret identity and girls supporting girls internet fame.
I couldn’t get enough of our main couple or the side characters,
not-so-imaginary-cats included.

I couldn’t recommend this book enough. August couldn’t come sooner. Don’t be surprised when my hair goes from red to pink.

*Firstly, thank you to Netgalley and Berkley for the arc!*

I want to start by saying I was not a fan of this book. While I did like the Love Hypothesis (I found it fun and really quick to read), this one just fell short for me. I do have to admire the fact that the author does have a couple novellas lined up so they have a lot going on right now, so it's pretty impressive that this book is being published so quick! In an effort to remain positive in a negative world, I will be starting with what I liked about the book before moving on to the issues I had with it. While these issues might be some things that bothered me, they may not necessarily bother you so take this review with a pinch of salt.

What I liked (and what you might like):
This book definitely checks off all the boxes of a typical rom-com. You have your tall, big, beautiful-eyed male love interest, and your shorter, quirkier, overthinking protagonist. You had all the Hallmark moments and then some. I also absolutely have to admire how amazing the marketing was for this and her last book. The whole "Steminist" branding certainly is a unique, catchy, one and it grabbed me. I wasn't the greatest fan of The Love Hypothesis, but I still chose to read this book for two reasons, 1) because the entire steminist branding just pulled me in, and 2) I wanted to see if the author had grown at all. This book caters perfectly to a Gen Z audience but I'm not sure if it would appeal to any other generations. Gen Z is sure to love all the "wokeness" and such within this novel. I think the only thing I truly liked about this book was Schmac and Marie's online relationship.

What I didn't like:
This entire book, much like TLH, felt juvenile and immature. The plot fell flat for me and the pacing had me wanting to dnf the book after a few chapters. The reader doesn't really connect with the characters (I found myself reading about one of the character's Tragic Backstory and absolutely could not bring myself to care for it) and the whole thing is a little insta-lovey. If you love insta-love, then I'm sure this book is for you. The book starts off with the love interest already basically being in love with her (obviously, as with most dense protagonists, the main character is entirely unaware). There is absolutely no build-up, no angst, no shy glances or anything. I felt the opposite of butterflies- reading this book made me cringe. It was extremely predictable (again, some people like predictable rom-coms!). Additionally, the main character only seems to swoon when the love interest does the bare minimum for her, I get this was the message- that the bare minimum is so abnormal that it's actually swoon-worthy when someone does it, but that doesn't change the fact that it was the bare minimum.

Overall, I don't think I'll be picking up another one of her books (or maybe I might, I am obsessed with the Steminist branding!). This is a typical TikTok book, one that felt wattpaddy, disjointed, choppy, and generic. There's no doubt in my mind that this book will sell well to its intended audience, but personally these books aren't for me.

There are times where you just want to read a book that takes you away from real life. A book where you can lose yourself in the lives of other people and not have to think about what is going on in the world right now. And this was the perfect book for that purpose.

While there are deeper subtexts of sexism, being a woman in STEM and science-related fields it is also a love story at heart. The usual tropes are here: meet-uglies, miscommunication, pining, etc. but the dialogue is crisp and the story won me over. I could see several of the plot points coming from a mile away but with a story I liked this much it didn't bother me.

This was the first title I have read by this author and I would read more of her books.

I absolutely loved this book. The main character is smart and funny, and the miscommunication is frustratingly wonderful! I will definitely be recommending this at my store and cannot wait to purchase the book when it comes out!

Another fun romance by Ali Hazelwood.
What happens when you get your dream job at NASA but are forced to partner with someone you know hated you all through grad school ? Now you think he’s trying to sabotage your success?
Things get very confusing for the brilliant neuroscientist Bee Königswasser. Especially when her partner Is very handsome and vegan too?? What would her role model Marie Currie do? It’s worth checking out this clever and funny romance.

4.5 stars

Ali Hazelwood is just an amazing writer! Just like The Love Hypothesis, she brings the science into romance and it is beautiful and refreshing. Bee and Levi are such well-thought characters with complicated backstories that make the story more interesting and complete. And so much love for Bee's assistant, Rocio. I am as amazed as Bee's sister on how Rocio manages to just top herself,

Why 4.5 instead of 5? Guy is just too annoying. Just too darn much. Like I just wanted to punch him so much and I get it, but still, no idea how a guy like that ever could have ever been part of the space program, let alone Levi actually have hung out with him.

Overall though, read this book! It is so exciting how many more books Ali has just on the horizon and I can't wait to just keep reading her works!

Thanks to NetGalley for the ARC.

Ali Hazelwood and this series has quickly become one of my favorites. Such an enjoyable swoony read that I couldn't put down. I think this series has a lot of mass appeal, especially for readers who like modern romcoms or enemies to lovers and workplace romance tropes. I enjoyed the secondary characters and setting, but the main draw was definitely the tension and chemistry between Bee and Levi - very satisfying.

This is a phenomenal sophomore novel from Ali Hazelwood, and I am already itching for more from her. I am pleased to report that Love on the Brain gave me the same feelings as Love Hypothesis did, which is to say, exactly what I wanted it to do. And there are certainly a lot of similarities between the two novels, with the Grumpy x Sunshine leads, the years-long pining, and a misunderstanding or two. But it's a formula that works fabulously, especially with Hazelwood's wit and charm woven throughout, so why mess with something that works. And this really, really works. Bee is so wonderful a lead here. Her spirit is free though her heart is guarded, and it makes for a character you can't not love and root for. Levi is everything you want him to be and somehow even more.
Then there's the science which is just fascinating in and of itself. I love this aspect of Hazelwood's novels even when the actual science is way over my head. It's just interesting, and even if you took all the romance plot out, there would still be an interesting story going on. But the romance is of course the star, do not get me wrong. It will fill your heart feel simultaneous like it's going by too slow because you just want to have ALL of it right away, and like it's going by way too fast because you're running out of pages and you don't want to be over. Which is equal parts satisfying and frustrating, so all we can do is wait for the next Hazelwood story and reread this and Love Hypothesis endlessly until that day comes. Hazelwood has officially cemented her status as an insta-buy author for me, as I'm sure will be the case with many, many others once they read this knockout of a story.

Ali Hazelwood has done it again. Did I read this entire book in one sitting? Yes. Did it leave me wanting more? Also yes. Am I excited for whatever Ali Hazelwood writes next? YES! As a woman in STEM - this new genre of STEM-inist rom-com has me absolutely HOOKED. Enemies to lovers, forced (work) proximity, witty banter, AND science? Be still my STEM-inist heart. I love Bee, love love love her. She is a badass who knows her worth (despite being terrified of commitment) and she is smart, she is funny, she is gorgeous, and she loves coffee. When she comes to work at NASA for a dream project to reach her goal of running her lab - enter forced work proximity with her nemesis - Levi. And man, while I'm not quite ready to say forget Adam Carlson - HELLOOOOO LEVI!

Love on the Brain is a stellar sophomore novel by Ali Hazelwood, and readers of her debut novel Love Hypothesis will also love this novel as well. Hazelwood provides a stellar cast of diverse characters and representation with a heaping dose of witty banter to go along with it. I absolutely ADORE Rocio, and want her to be my friend in real life. Also, science based cat names?!?! I AM SOLD. While this is still a slow burn romance, we do get more steamy scenes in this book which I am all for. Also, hello plot twist that my brain didn't see coming until right when it was about to occur.

Despite the rom-com of it all, Love on the Brain addresses serious topics that continue to be a major problem in the world of STEM such as toxic relationships, gender inequality, standardized testing, and inaccessibility to graduate education. As a woman in STEM academics, I appreciate the awareness that is being brought to these topics and the enjoyable ride we get along the way. I cannot WAIT to read more from Ali Hazelwood.

I really liked the love hypothesis and I enjoyed this one just as much. There were a lot of similarities between the two but that isn’t a bad thing. I liked the enemies to lovers storyline and I really liked her assistance. I enjoyed the focus on women in STEM and all the Marie Curie stuff as well
