I love this book. It started out slow until she decides whether to go with Ethan or gabby. I love how every chapter switches from one reality to the other. 
 Throughout reading this book, when I'm in one reality and discover something, I'm thinking oh no how is it going to develop in the other reality. 
 The author does a beautiful job of writing both realities and I was rooting for both Ethan and Henry. Although, I got to admit. I liked Henry a little more. I just feel like they have more in common. Both realities ended happily. I was satisfied. 
 I love what Jesse says about multiverse theory about a new reality with a coin flipped with heads and a reality with tails. It's fascinating! 
 Really enjoyed reading this and viewing two different realities that Hannah experiences.
