After reading Everything, Everything, I knew I couldn't wait for Nicola Yoon's next book. Unfortunately, this book was not for me. I wanted to love it but I couldn't. 
 I did like that chapters alternated between Daniel and Natasha, and we see how both of their stories unfold. We also get chapters narrated by the people around Natasha and Daniel, and we see the history and stories of people on the periphery of their lives. I don't know how I feel about those chapters. They made me feel even more removed from what was going on, and we see how the choices others made led to this moment in their lives. 
 If you don't like insta-love, this is not the book for you. Even worse, this book tries to SCIENTIFICALLY EXPLAIN insta-love. My reaction to this: no. Please, no. Do not try to scientifically explain insta-love. That is the last thing I want to read. I thought they had no chemistry and it was creepy how obsessed Daniel was with Natasha, and how much he believed that they were meant to be together. You only caught a glimpse of her, and you decided that she was The One? Thanks, but no thanks. 
 I felt so bad for Natasha, who had to go back to a country that didn't feel like home to her. I get why they had to go back, and the thing with the lawyer? She went to him for help, and he couldn't even do that because he was too focused on his paralegal. I liked that she had hope, yet didn't want to say something until she knew for sure what was going to happen. I did feel for Daniel, and the pressure his parents (especially his father) put on him. Something about Daniel's family in particular seemed very stereotypical to me but at the same time, that was much more interesting to me than the romance between Natasha and Daniel. I really wish the story was more about them and their families then their romance. 
 My Rating: 2 stars. I liked it a lot less than Everything, Everything, and the romance (and scientific explanation of it) were not for me. I did like the family dynamics and the thing both Natasha and Daniel were facing.
