Nora Reid believes scientific laws control everything, even love. With her grandparents’ epic first kiss story cemented in her brain, Nora develops a hypothesis she’s determined to prove:for each person in the world, there is exactly one other person, and at first kiss, they’ll experience an immediate and intense reaction.
But after four years of zero-reaction kisses, she comes up with a new theory: maybe that pesky crush on her stunningly hot best friend Eli Costas is skewing her results.
She needs to get rid of him, and fast.
Eli Costas is an injury-prone lacrosse star with a problem—the one chance he had at winning over the girl next door resulted in the most epically sucktastic first kiss ever. And now she’s…trying to get rid of him? Hell no. It’s time to disprove her theory and show her exactly what she’s missing.
Game. On.
Disclaimer: This book contains a stunningly hot lacrosse player who isn’t above playing dirty to win over the stubborn girl-next-door of his dreams.



I’m a romance nerd and ridiculously addicted to Entangled Teen (Crush) books. They’re delightful, cutesy, and so much fun to read. The First Kiss Hypothesis by Christina Mandelski is no exception and had me hooked from the beginning.

I LOVE friends to lovers stories and this one most definitely did not disappoint. The plot was entertaining, hilarious, and had plenty of sweet moments that made me smile like a dork. Nora’s theory about finding true love, while quite silly and something I would never do, was a unique concept that had me intrigued the entire time. Some parts of story were clichéd as expected and a bit cheesy, but who am I kidding… I LOVED IT ALL! And that ending… that final scene at the beach — gave me insane FEELS. I reread it over and over cause I could not let go of this lovely story and Nora and Eli.

Speaking of Nora and Eli, they were both frustrating at times, but totally made my heart melt. Through the ups and downs, the misunderstandings, and the drama, they made me feel like a teenager falling in love for the first time and I enjoyed every moment. They’re so stinkin’ cute together… specially when they’re bickering and challenging each other. And their chemistry – absolutely steamy and sweet with plenty of close call scenes that had me holding my breath. I don’t want to give too much away, but Nora and Eli’s love story is positively charming. Not to mention, it involves a lot of pies… lots and lots of yummy pies!

Oh and one more thing… Eli’s younger brother, Ari, was all kinds of adorable and cuteness. He added more heart to the story and I loved his interactions with Eli and Nora. He’s sweet, smart, and endearing in every way.

The First Kiss Hypothesis is satisfyingly sweet, deliciously adorable, and irresistibly swoony! I honestly had so much fun with this book and cannot wait to read whatever Christina Mandelski writes next. If you’re in the mood for a light hearted cute romance, then I highly suggest you pick this up!

I received an advanced reader copy of this book from the publisher via NetGalley in exchange for a fair review. All thoughts and opinions are my own.
