I read this book in a day! I Love Ali Hazelwood, & the world she has built with her books! I’m not a STEM girl, & honestly I hated science class in school, but this world she created is addicting, even without a love of science! I loved seeing the callbacks & Easter eggs from her other books too; especially the cameos of past characters Adam & Olive! I loved being able to see what they are up to now!
As for the characters in this book, their chemistry was off the charts, Jack & Elsie make an adorable pair, & it’s fun seeing a fake dating trope where the couple that’s faking it ISNT the ones who fall in love! Not something you see often. 
But also, this book really called me out with Elsie & her people pleasing!  I’m not as good as Elsie, I can’t read people & make myself into the version they want, but I do people please A LOT! & some of the quotes in this book really hit close to home!  Idk if that’s a good thing or not yet. Lol 🤷🏻‍♀️
