3.5 stars
I found the main character, Bee, a bit annoying. Crying every time she sees roadkill seems overdramatic, even for a vegan. I was more invested in Levi than in Bee, and I was frustrated that it seemed like Ali Hazelwood didn't do a lot of research on Texas--or even Houston, or she might've made a comment on Houston traffic or how absurdly large it is. The ending conflict felt forced; I didn't think it was believable for a second that Guy would be the mastermind, and giving him a gun seemed to be another "I didn't do my research on Texas" situation (also, I know it was the middle of the night, but why was he able to bring a gun into NASA?). I thought it would've been more believable to have Boris be the villain, and for him to be engaging in some corporate espionage--secretly working for both NASA and MagTech (which mysteriously disappeared from the narrative after the convention). I'm also bothered by the fact that we never found out what Levi said to Tim at brunch, though I realize that may just be a me problem.

I'm not sure how I can even put into words how much I adore this book! In fact, The Love Hypothesis was one of my favorites last year, and somehow this managed to top it, I think.

First of all, Bee is the protagonist to root for. She's quirky, relatable, and down right hysterical, cue me trying to hide my fit of giggles at 3am as to not wake my husband while reading this book when I should have been long asleep. And of course I'm a sucker for hate to love, so naturally I was head over heels for the dynamic between Bee and Levi. It hit on all the right points: excellent banter, angry musings, delicious forced proximity, and oh-so-many feels. To my delight, I was even trash over the side characters, which is honestly rare for me. Everyone who stepped on the page felt very three dimensional and real in a way sometimes my own life doesn't live up to (sad? probably).

Basically, to all my rom com lovers and beyond, this is a book to snatch. Don't miss it!

After having an absolute blast reading The Love Hypothesis last year, Love on the Brain became one of my most anticipated reads of 2022. So, imagine how ecstatic I was when I recently got approved for an ARC!

I gotta say, Ali Hazelwood knows how to write an entertaining book. Do you sometimes have to suspend your disbelief in order to enjoy her stories? Yes. Do they kind of read like wattpad stories? Yes, but in the best way possible!

Although it may seem ridiculous to some readers, I have never related to a character’s quirk as much as I did with Bee’s spontaneous fainting. It happens to me all. the. time. I once fainted in front of my whole high school grade because a guy pushed me a bit too hard against my locker by accident. I woke up with my History teacher waving his fingers in my face. Yep, that happened, and so I loved seeing my annoyingly weak blood pressure response being represented in my favorite format. It made it feel normal, funny even, which I liked.

I also enjoyed Bee and Levi’s characters a lot, but then again, they were practically decoys of Olive and Adam, especially Levi. Which isn’t a bad thing, but it did make me feel like I wasn’t reading something new. Like I was reading another version of The Love Hypothesis. A lot of the things that happened also felt quite similar to Hazelwood’s debut. Still, while I noticed the similarities, they didn’t affect my overall enjoyment of the story. I just hope that the author’s next publication will stand out a bit more, explore different topics and tropes. That would be cool.

Overall, although I didn’t enjoy it as much as The Love Hypothesis, Love on the Brain was still an entertaining and fun read. Ali Hazelwood is quickly becoming an auto-buy author for me. I just hope she switches things up a bit in the next one.

This book was another compelling read by Ali Hazelwood. She writes a really great grumpy meets sunshine trope. Essentially, two very smart STEM people (neuroscientist and an engineer) who knew each other in grad school end up working together on a high-profile project at NASA. She thinks he's ignoring/being rude to her, he' has his own secrets that explain his behavior, feelings are realized in dramatic fashion. Would I buy this in a store with my own money? Yes. Would I check it out from the library? Definitely. Good for fans of contemporary romance with STEM details.

Thanks to NetGalley and the publisher for the ARC.

I don't even know where to start, this was SO GOOD.

I read it in one sitting and I would die for Bee and Levi. Particularly Levi??? He is amazing??? I die.

Every character in this book felt fully formed, and the plot was fascinating aside from the steamy romance. Also, there are more smut scenes! And they are excellent!!!

ICONIC.

3.5

I wanted this to blow me out of the water like Love Hypothesis did. And it was very cute! But I found the beginning relied way too heavily on the miscommunication trope. There were two big reveals in this book and I guessed the first one the moment the situation was introduced so that was sadly predictable. The second twist I did not see coming but it was very abrupt and out of nowhere so it didn't sit great with me. The spice and relationships were an easy 5/5 though.

Overall I am obsessed with Ali Hazelwood and her writing style. She writes amazing and diverse characters and I love how she brings awareness to women in STEM in all her books. The main reason this isn't a perfect rating for me is the pacing issues, the miscommunication trope and the predictability.

Thank you so much to the publisher for the ARC I got for this (:
I want to be clear that my review is 4.5 ⭐️☺️💕.
I highly enjoyed this I was concerned it would be too much like the love hypothesis but I think it was only like the love hypothesis in the BEST ways (women in stem, a few tropes I love)
Speaking of tropes love on the brain uses only the best ones, chatting online without knowing who the other is and a few others I won’t mention of spoiler-y territory.
Also I think I just love the characters Ali Hazelwood writes, I am not in stem and am not really a science person but I found Bee (and olive) relatable in other little ways which made me feel connected to them.
Please read this if you liked the love hypothesis and honestly I recommend to anyone

(Also to be clear I’m giving it a 4.5 and not a 5 bc I am unfairly comparing Levi to adam and I just really loved adam)

What would Marie do? She would stop what's she's doing to read this book.

Ali Hazelwood is a delightful writer and
Love on the Brain might be my new favorite! This book is charming, addicting, and incredibly binge-worthy.

Bee and Levi attended the same grad school, and it's well known by everyone that they are nemesis'. Years later Bee and Levi are selected to work on a a NIH-NASA collaboration, project BLINK. They are incredibly passionate about BLINK and want it to succeed. They decide to work together and just happen to find out they don't really hate each other in the process.

An enemies to lovers romance with science that you didnt know you needed!

Thank you to NetGalley and Berkley for the e-ARC of Love on the Brain.

I loved this book so much! The Love Hypothesis was such a delight, so I was so happy to be approved for an e-ARC of Ali Hazelwood's newest book. Love On the Brain has the same banter and smarts, and general bada** women in STEM feel as The Love Hypothesis had, but with a different story and characters. Levi was much more unlikeable at the beginning, but once Bee (and the reader) got to know him, he became so loveable and amazing. I liked that he had to earn the heroine's love and friendship, as well as the reader's esteem, and that Bee's dislike for him and misreading his interest in her as hostile when they were in grad school was not just her being clueless but something that everyone else around them thought, as well.

Just like The Love Hypothesis, Ali Hazelwood doesn't shy away from having plenty of scienc-y conversations between characters, which I love. She writes these conversations in a way that makes them fairly easy to follow even for non-scientists, but doesn't make it fell like she is having to explain things or dumb things down for the audience to understand.

Overall, this was a wonderful read, different from Ali Hazelwood's debut but a worthy successor. I cannot wait for more books from her!

I didn't think Ali Hazelwood to top The Love Hypothesis, but she has with Love on the Brain. I was obsessed with Levi and Bee, their stories and their swoon. Set a reminder on your calendar and pre-order this book immediately.

I love relatable characters! I love how nerdy and wonderful they go together, and the storytelling is vibrant and lively. The banter is also excellent. Definitely will recommend this book!

This book just made me want to quit everything and never stop reading. Until it ended and now I am set adrift. I am 100% an Arts person but holy smokes this book makes science fun and makes me question my degree of choice...just a smidgen. I love when ladies show off their brains and Ali writes the best smart ladies. And don't get me started on the romance! Delicious. I cannot wait until the next one.

This book was so good. I love the fem-scientist aspect and the banter. The right balance of frenemies and love to keep me rooting for the love interest. Also, cats!

I liked this better than Love Hypothesis, however, it still felt a bit boring in some places. The characters seemed very similar to Adam and Olive but I did find that they seemed to have more chemistry! I really enjoyed the sex scenes though! Especially since there was more than one which annoyed me about the first book. An enjoyable read all in all and I will probably read other books by this author.

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!
