Love on the Brain

An Instant New York Times Bestseller

A #1 LibraryReads and Indie Next Pick!

From the New York Times bestselling author of The Love Hypothesis comes a new STEMinist rom-com in which a scientist is forced to work on a project with her nemesis—with explosive results.


Like an avenging, purple-haired Jedi bringing balance to the mansplained universe, Bee Königswasser lives by a simple code: What would Marie Curie do? If NASA offered her the lead on a neuroengineering project—a literal dream come true after years scraping by on the crumbs of academia—Marie would accept without hesitation. Duh. But the mother of modern physics never had to co-lead with Levi Ward.
 
Sure, Levi is attractive in a tall, dark, and piercing-eyes kind of way. And sure, he caught her in his powerfully corded arms like a romance novel hero when she accidentally damseled in distress on her first day in the lab. But Levi made his feelings toward Bee very clear in grad school—archenemies work best employed in their own galaxies far, far away.
 
Now, her equipment is missing, the staff is ignoring her, and Bee finds her floundering career in somewhat of a pickle. Perhaps it’s her occipital cortex playing tricks on her, but Bee could swear she can see Levi softening into an ally, backing her plays, seconding her ideas
devouring her with those eyes. And the possibilities have all her neurons firing. But when it comes time to actually make a move and put her heart on the line, there’s only one question that matters: What will Bee Königswasser do?

Love on the Brain – Book Review In Love on the Brain, we meet Bee, a passionate neuroscientist who’s just landed the opportunity of a lifetime: co-leading a cutting-edge neuroengineering project with NASA. It’s everything she’s worked for—until she finds out she’ll be sharing the role with Levi Ward, her aloof and seemingly hostile grad school nemesis. Bee is convinced Levi can’t stand her and would rather see her fail than collaborate. But when odd setbacks begin to derail the project—missing equipment, unexplained delays—Levi surprisingly steps up as an ally. As he reveals a softer, more sincere side, Bee begins to question everything she thought she knew about him. And when it comes time to take a leap of faith, will Bee have the courage to follow her heart? A sweet friend of mine (thank you Kitty! @kittyleestboeken đŸ«¶) recommended Love on the Brain after I gushed about The Love Hypothesis, promising it had the same cozy, comfort-read energy. She was right (not that I ever doubted her 😉)! While The Love Hypothesis still holds the top spot for me, this one came closer than I expected. It’s overall an adorable, nerdy STEM rom-com filled with clever banter, fun characters, and plenty of heart. Bee was instantly likable—I may not share her science-savvy brain, but I connected with her in plenty of other ways. Levi took a bit longer to win me over, but once his true intentions were revealed, I found myself rooting for him just as much. Their shared love of cats and animals? An absolute bonus. đŸ˜» The book also includes meaningful chronic illness representation—something I’m always grateful to see. Bee navigates life with a fainting disorder, while Penny, who has epilepsy, truly shines as a supporting character. She’s an absolute delight and reminded me so much of my sweet Clara. 💗 While the plot was definitely predictable, it delivered that familiar, comforting feeling I love in a good rom-com. That said, I know predictability might be a drawback for some readers, so it’s worth mentioning. There’s moderate language and a decent amount of smut near the end, which may not be for everyone. It’s not my particular cup of tea. All in all, this was a feel-good read I’d happily revisit, just skipping all the spice next time. Due to the language, smut, and a few elements that go against my personal beliefs, I’m giving it a 4.25 ⭐. Without those things, it easily would’ve been a solid 5 ⭐ for me. ___________ QOTD: What’s your favorite enemies to lovers romance you’ve read?

2.5⭐ This book just didn’t do it for me. I can’t explain it but after love hypothesis it just didn’t work for me and I was unfortunately dissatisfied and DNF’d it
