Hypothesis: "For each person in the world, there is exactly one other person who, at first kiss, causes an immediate and intense reaction."

Nora believes this Hypothesis and is trying to find her first kisses. Her methods include charity Kissing booths and plenty of first dates. Her grandmother found her soulmate after one kiss and married 2 weeks later. Nora wants her experience.

Eli is trying to prove the hypothesis is untrue. Nora and Eli have already shared their first kiss and it wasn't magic. Nora sprang it on him and he wasn't ready. It was awkward and a total disaster for there relationship. Luckily they got over it and now are back to being best friends. I've read a lot of best friend romance books lately and I liked the fact this one was a little different. Both characters already know they like the other they just need to find the right page.

Nora wants to be a scientist and is a believer in proven theories. She studies hard and spends her free time with Eli. She dates, but unsuccessful thanks to her hypothesis. It has made her distance from other students at her school. She wants to get over her crush on Eli, but she needs his help first.

Eli has had enough of Nora's one and done. He intends to show her she may miss out on true love if she doesn't give up her science project. With some intense driving, some delicious pie and a cute younger brother- The first kiss hypothesis is a sweet original story.

4 Stars out of 5. *I received an ARC of this book in exchange for an honest review as part of the Chapter by Chapter blog tour*

Nora and Eli are the cutest. For reals. I really enjoyed this light hearted YA Romance.
Nora meets Eli. Nora is a scientist and she has a theory. The first kiss should determine whether or not this person is going to be the love of your life….that is what happened to her grandparents so that’s feasible right? When she and Eli have that first magical kiss it is so bad that Eli is placed in the friend zone for years!
This story made me smile. It was light and well written. Christina does a great job writing teenagers. It was refreshing and different than all the dark and gloom that I have read this October. I loved that Eli and Nora did not throw everything aside for love. It was very realistic that their lives were to go on within all the drama. The story wrapped up well and I was left with a settled feeling. I would absolutely recommend The First Kiss Hypothesis to anyone who enjoys YA Romance.
