I'm beginning to think Ali Hazelwood is going to be one of my go-to authors. I loved this book so much! I adored Bee and Levi so much, both together and individually. The banter was hilarious and there were so many details I enjoyed about this book, such as Star Wars references, cats, the WWMD twitter page-- literally SO good and I never wanted to put it down! It didn't quite hit five stars for me because I was confused fairly often throughout because there are *so many* science/neuroscience/NASA references that I just simply do not understand lol. I found myself googling every now and then to look up a specific word or person mentioned. Other than that bit, I loved this and totally recommend!
