Plot Summary

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 – 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. But Levi made his feelings toward Bee very clear in grad school – archenemies work best employed in their own galaxies far, far away.

But when her equipment starts to go missing and the staff ignore her, Bee could swear she sees Levi softening into an ally, backing her plays, seconding her ideas… devouring her with those eyes. 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?

My Review

The book starts off spectacularly with the very famous tropes ‘guy falls first’ and the old but goody ‘enemies to lovers’.  Bee is a really smart neuroscientist who starts working at NASA in a deal breaking project. The problem? She has to team up with Levi Ward…who supposedly hates her guts. The thing is…he clearly doesn’t and everyone knows that (I know that, you know that) except Bee. She’s a very insecure young girl who loves to ramble and misinterpret others’ reactions and feelings. I really liked her character but the damn girl was very very blind regarding the love department.

Levi I simply adored but not at first: that comment about the clothes she was wearing really struck a nerve. 

I went into this book with very excitement and with an open mind but I also had a feeling this wasn’t going to be as good as The Love Hypothesis and I was right. 

There wasn’t the magic, the full personality and relationship between Levi and Bee like there was with Adam and Olive. Those two just connected perfectly. 

That is why I couldn’t, in my right mind, give Love on the Brain the same rating I gave The Love Hypothesis because there are certain stories that are simply unique and can’t be repeated and this is a good example. Ali tried to give the same vibe but couldn’t quite reach it.

I absolutely hated the villain plot in this story. I think it didn’t make any sense and the only reason it was there was to give a tense moment to the main characters.

Nevertheless, Ali is a great writer and this was a very entertaining story.

Highlight Moments

– The cemetery rescue

– Levi’s confession

– The pen pals scenes


“You don’t even have to admit to yourself that you love me, Bee. God knows I love you enough for the both of us”

“Why does Tim look terrified?” He gives me an innocent look. “He does?” “Levi. What did you say to him?”

“The distance between us is perfectly appropriate. It just feels like it isn’t, because Levi is so large. And warm. Because he’s Levi”

“It sounds sketchy. Like he’s trying to lure me to a secondary location to traffic me to people who’ll harvest my femurs to make handles for badminton racquets.”

PLOT: ★★★
COVER: ★★★★
