Love on the Brain

By Ali Hazelwood

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?

El que menos me gustó de ali. Me tarde un montón en leerlo porque no me atrapaba, el principio y final no me gustaron y al medio si pero faltaba algo. Lo del intento de asesinato fue muy raro y ya se veía desde lejos que los malos eran o guy o kaylee.

I loved this book!! Love Hypothesis was good too but this one was probably my favorite because I related more to Bee than Olive. It was soooo funny and I cried a couple times! I am so excited for “Love Actually”!

4.5 stars rounded up! I had so much fun reading Love on the Brain! I didn't want to set it down, staying up into the wee hours of the night to finish it. The setting of NASA in Houston was fun because I've been there, and that always enhances a book for me. I adored the characters. This one wasn't perfect, but did I care?? Not one bit.
