It was a little predictable and not as fully formed as The Love Hypothesis was. But it was still a fun read and a decent romcom.

I loved the male main character, Levi, more than I did Adam from The Love Hypothesis. He was likable but not too perfect which made their romance more realistic. It was a sweet, slow-burn (kind of) and I loved it!

I'm pretty conflicted on my feelings for this book. Half of me loves it and the other half loathes it. I did enjoy my time with it but this book had me rolling my eyes about a million and one times. I found Bee, the main character, to be incredibly hypocritical and unlikable. It's hard to thoroughly enjoy a story when the character you're taking the journey with aggravates the hell out you. What I did love about the story though was the romance. It was fun and kept me turning the pages. Overall I do recommend this book and could see a lot of romance readers loving it.

This book!!! I enjoyed The Love Hypothesis, although it also stressed me out majorly because I personally have some triggers around academia-set romances. But in Love on the Brain, we get the smart people without the university setting, and I absolutely adored every second. I was in a reading slump before I started, and this book really got me out of it. I zoomed through, loving every second. It's fun, it's funny, Bee is a wonderful protagonist, Levi is dreamy, and the spicy scenes in this were just extremely extremely well-written and sexy. I also appreciated that the You've Got Mail situation wasn't played up in a way that would create unnecessary drama; the stakes felt perfect as it was and I'm glad things didn't get derailed.

Hazelwood is so adept at laying out a perfectly normal situation that gets completely misconstrued. Through a series of assumptions, misconceptions, and just plain unknowns, she builds conditions impossible for romance. Add to that the side conversation via Twitter DMs where the frenemies unwittingly bare their souls and you're squealing in delight. Hazelwood's big reveals are not to be missed.

Ali Hazelwood is back with another fun, frothy romance novel set in the world of STEM and academia. I have underestimated how much I enjoy my main characters chatting about neuroscience and engineering. Also, NASA.

My god, Ali Hazelwood can do no wrong. This book hooked me from the very beginning and dare I say that I loved it even more than The love Hypothesis. There was something about Bee that was extremely relatable. She was down to earth and also extremely smart. Now Levi… he was something else. He can do no wrong in my eyes. There were several moments where I had to put the book down and walk away because of how cute the two of them were. I would definitely recommend this to anyone who needs a light hearted read. Thanks for sending me an arc!

THIS IS A VERY CUTE NERDY BOOK.

Loved the "enemies to lovers" trope, loved Bee and Levi, and of course the side characters who get their own full story as well. It got a little too open door focused for a few chapters before circling back to the main plot, but overall I loved this book - I think I may like it even better than her first!

Also, there's a really fun "Scream" line in it.

When I finished Love on the Brain, I slow-clapped, cried, and did a handspring. (Internally. My handspring days are over.) Then I dipped back into my favorite scenes, because I wasn't ready to leave the world Ali Hazelwood created. This witty, sexy rom-com is FUN to read. It's also bursting with heart and braininess both. Endearingly nerdy neuroscientist Bee has the chance to jumpstart her career heading up a major project at NASA. But her collaborator is her grad school nemesis, Levi, a huge, hot, inexplicably hostile star engineer. Hazelwood delights in serving up classic tropes made from zesty fresh ingredients. Thanks to Bee's hilarious narration, and much needed super-sharp takes on workplace misogyny, the enemies-to-lovers, forced proximity dynamics feel self-aware, satisfyingly familiar, and also new. Hazelwood is brilliant at characterization, all driven by that unforgettable first-person voice, and the pining main characters develop with exponentially-increasing intensity across the book, breaking out of their boxes and accessing hidden strengths (and wow, hotness). The supporting characters are lively and dynamic and flesh out the story with their own messy (in certain cases absolutely adorable) lives. For a novel that clips along sacrificing none of the jokes or the opportunities for melodrama, Love on the Brain manages to sound astounding depths and to confront tough issues; it entertains and educates and creates a powerful emotional experience. Love on the Brain does a lot at once--a hefty achievement and even more amazing because Hazelwood makes it seem so effortless, and because the effect is sparkles and light. This is a spectacular follow up to The Love Hypothesis. I'm even more excited to read every word that Ali Hazelwood writes (even the words that are peer reviewed.) Highly recommended.

I loved this book so much. Ali Hazelwood has my heart and soul. Everything about it was perfect. I made a joke about the rom com formula but she actually went off script in such a pleasant and surprising way. 5/5 on everything I would give it 10/5 if I could

I loved, loved, loved this book. I loved it just as much as The Love Hypothesis. As an avid lover of rivals-to-lovers and yearning, this was such a delight. Will recommend to everyone I know.

Love on the Brain was the rare second book that was even better than the debut. The writing was stronger, the characters felt even richer, and the mystery plot was well crafted enough that it stood on its own alongside the romance plot. I cannot wait to see what Ali Hazelwood does next!

All opinions are my own. Another knock it out of the park for hazelwood, We have a new queen of romance in the making. If you are a woman in stem in search of hea this book is for you. It shows that books and covers aren’t as they appear and everyone can find their person. In the arc may change between now and publishing, the Mc is a badass vegan hair coloring scientist. I mean epic let’s be real we are also slightly couch potatoes more then we should be and if I could have a research assistant I would totally want either of the epic ones in this book. This won’t disappoint fans of the love hypothesis…. I can’t wait for more from hazelwood….

Levi and Bee's relationship in "Love on the Brain" is certainly swoon-worthy. She firmly believes that he has hated her since he met her but finds... she might not have had everything right. I enjoyed this book, and it lacked some of the more frustrating parts of Love Hypothesis - mainly an incredibly smart woman missing the obvious signs right in front of her! However I think both Levi and Bee's pasts, families and insecurities could have been explained more fully, as they could have used more depth. A fun read, though not one I will be returning to.

After reading The Love Hypothesis by this author (which I found very enjoyable), I was looking forward to her next release, Love on the Brain. Unfortunately, I found it to be less engaging. The story of engineering project the main character was working on just seemed to drag on with the same story line repeating itself. The romance was good, but felt a little forced. I found myself skimming over parts just waiting for the story to pick up the pace or take a new turn. I also found the main character, Bee, to seem more like a YA character in an adult romance. As an accomplished scientist the purple hair, nose piercing and lack of commitment just felt unbelievable.

This was my second Ali Hazelwood book, and once again, I am not disappointed. I found the character funny and relatable. I could completely understand how they fell in love with each other. I am not a science-minded person, so I appreciated that any science was described for people like me!

Love on the Brain is one of those un-put-downable, up till 3 am kind of books. Seriously, I read this in one sitting and I loved every second of it. I enjoyed this book just as much as I did The Love Hypothesis, which I think is a lot to live up to.

What I loved: The characters were very relatable and fun, STEM representation, the romance build-up was well done and not rushed.
What I enjoyed less: Similar conflict as in Hazelwood's first book (predictable bad guy, doing bad guy things right at the end of the story).

Overall, I had a blast reading it and will be recommending it to other romance lovers.

The author of The Love Hypothesis has outdone herself with this book! Another funny, sweet, steamy romance centering women in STEM, and I loved it even more than its predecessor. The dynamic between the two main characters is 100% binge-worthy, and the homage to "You've Got Mail" was an unexpected delight.

One thing I particularly liked about the main character of this one was her appreciation of the strengths of different types of women- it's just NICE to see no female-against-female rivalries and no judgements. The characterizations of all the women in this book were very validating.

And the male love interest... well, swoon! Sort of a science-y Roy Kent type.

Loved every bit of this book- I couldn't put it down. I have trouble focusing these days, but this one made me want to drop absolutely everything and just read. I loved it and can't wait to recommend it at my library.

Thanks to Netgalley and Berkley for access to the advance reader copy!

Ali Hazelwood's latest novel is a charming love story. Despite being predictable at times, there are surprising twists and a heartfelt love story. An excellent read!

This. Book.

I am a huge fan of this author - her books are clever, engaging, and hilarious. Her characters are relatable, and the situations both ridiculous and entertaining.

Bee and Levi are heartbreakingly adorable. Bee is so open and honest and Levi is so emotionally restricted the tension between them is both understandable and frustrating. I love how Bee is so matter-of-fact about how she thinks Levi hates her, and he is so addled by his feelings for her he can't even disagree.

The "twist" actually did take me by surprise, and I am still not sure how I feel about it. But no spoilers here.

Also, Bee's lab assistant totally reminded me of Audrey from Parks & Rec.

The scienc-y stuff in here is to die for, and I am in <3 with Hazelwood's characterization of how meetings go for women, and specifically women in the sciences. The Marie Curie angle is great, and the twitter page should actually exist.

PS - this was my first 5-star read of the year.

Thanks to NetGalley for the ARC!
