Spoilers below!!! 
 Okay, so everything was a lie... NOW WHAT?? Why doesn't Yoon finish the book? How does Madeline deal with her mother's mental illness? She just leaves her at that's that??? Nooooo. Ugh. I thought this was an interesting plot twist (that I sort of already knew) and now I understand why people aren't okay with it. Wishing and hoping doesn't make things like physical/mental illness better! Neither does love!!!! You have to learn to live your life how it is and with whatever life has given you. Plus, Madeline just goes off and flies just because??? Airports are sure to make you sick!! Ugh. 
 I didn't fall in love with Maddy. I just didn't. I wasn't into the insta-love I found in this novel. I enjoyed the little tidbits from their lives together, though. The cute drawings and diagrams of how to kiss were adorable, but I didn't feel it with her. I was happy for her and I wanted to know what happened after Hawaii but???? I don't know. It was all a lie and I want to know how she deals with it afterward!!!!! 
 I'm frustrated.
