4.5 stars Another STEM romance from the brilliant mind of Ali Hazelwood, and I must say that I this second outing better than her first book!!! The heroine, Bee, is smart, sassy and HILARIOUS. I was a little worried that her “Oh, he hates me” mindset with Levi would start to grate, but I only had to endure it for a little while before the story moves our characters past that (more or less). Whew! Solid story telling, I laughed out loud several times and thoroughly loved the ending/wrap-up. Well developed secondary characters abound and I learned lots about about the brain and now am an even bigger fan of Marie Currie! Super fun and satisfying read. Note: it’s pretty steamy in places, so if that’s your thing, you won’t be disappointed. Thank you NetGalley and the Berkeley Publishing Group for sharing this digital reviewer copy with me in exchange for my honest opinion.

Light and predictable, this is nevertheless a fun and cozy read. Humorous, romantic and sexy it will satisfy any romance lover. If you enjoyed Love Hypothesis, you will also love this one!

Thank you so much for the ARC!

Beyond excited for this next instalment of stem women falling in love, such a slow burn and Bee felt so real I could reach out and grab her by the shoulders at times. Though I enjoyed the Twitter account interactions, it felt a bit as if them not knowing went on for a little too long and when things blew up the reveal was overshadowed by Guy's sabatoge. I loved her love of Marie Curie as I didn't know anything about her beyond very basic facts. So romance and learning? Win win!

What else is there to say, but "CUTE"?! I loved the characters, I loved the story, I love the author!

I really can't wait for another book from Ali Hazelwood. It's really a joy to read about love in the STEM world.

Ali Hazelwood has quickly become one of my favorite authors. The way that she writes her characters, and the interactions between them, is just so VIBRANT.

They're dorky, they're awkward, they're relatable, they're hot and swoony and just absolutely stunning. I think her work really speaks for itself. See something authored by Ali Hazelwood? Just read it! I was in a huge reading slump until I read this book. Now I'm off to try and track down the release dates for her other books! :)

First things first: the most massive thank you to the author Ali Hazelwood, Berkley, and NetGalley for the e-ARC of this one! Love on the Brain is my number one most anticipated release of the year and it was an honor to get to read it early!

I read Love on the Brain primarily in one sitting and straight through the wee hours of the morning. If I’m looking at the clock shocked that it’s suddenly 3 am… the book is EXCELLENT, my friends. After The Love Hypothesis last year, there is simply nothing that Ali writes that I will not read. I would enthusiastically read her grocery list! After reading LOTB, I’ve come to the conclusion that I simply do not laugh or grin as hard except when reading an Ali Hazelhood book. Her writing style and humor fit my preferences so exactly, it’s almost eerie. She is a genius!

In this book, we meet Bee and Levi, a neuroscientist and an engineer respectively, and sworn enemies, now working together. Bee is absolutely HYSTERICAL and I loved getting to be inside her head. And Levi? *Definition of swooooooon worthy*. I cannot wait for everyone to meet them upon release!

I loved getting to see a window into neuroscience/engineering, and coming from someone that knows next to nothing about these fields, I felt very smart reading/learning about Bee and Levi’s project at NASA. Then add in the fact that the book also features: enemies to lovers and forced proximity (*chef’s kiss*), Twitter (I love Twitter and owe multiple my greatest moments to it so this was right up my alley), AND cats? *Extra chef’s kiss*.

In conclusion, Love on the Brain is laugh-out-loud funny, spicy, and reflects on the challenges women face while working in the male dominated world of STEM and academia. I cannot recommend it highly enough, and can’t wait to get my hands on whatever Ali releases next!

Bee gets her dream job, working in neuroscience on a project with NASA in Houston. The only problem? Her grad school nemesis Levi is working on the project as well.

I absolutely ADORED this book! The characters were funny and you can't help but root for both of them to admit their attraction. The mansplaining misogyny that is prevalent in science and technology fields felt realistic (and infuriating). I hope that we get a novella in the future to get an update on Bee and Levi. This is definitely a must-read if you enjoy contemporary romance.

Ali Hazelwood has done it again! Love on the brain was everything I wanted from Hazelwood. A quick and easy read. The characters were phenomenal and the story was entertaining. Going forward, I will continue to read anything and everything from Hazelwood.

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.

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, 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.
