 On one hand Tiffany Schmidt wrote a story that was hard to put down. I finished this in one night. But on the other hand, the 2 main characters, while they had depth, were hard to relate to and hard to like, the community they live in a caricature. 
 Brighton is always nice, to the point of suppressing the real her, and is striving to get 100% participation from her school so she can follow her dad's highschool footsteps. It seems silly - the 100% thing. So if she was in a year with 1 jerkward she was screwed? 
 I could sympathsize with her character, why she needed to be so perfect, sort of, but I couldn't relate to her. 
 Same with Jonah. I feel for his situation, a kid whose mom left his old life and took him to a new life with her new husband and new baby. His dad abandoned and blames him for the split. But he was so unnecessarily mean to Brighton until so late, and there was no reason for it. 
 I don't get what he saw, why the change in his feelings towards Brighton from contempt to the beginnings of love. Like another reviewer pointed out, in the space of this 1 day he just broke up with his long term significant other and childhood friend. Even if the relationship wasn't healthy in the last little while, he needed space for us to buy that this is not a rebound. Even in the last scenes we see the two leads struggle with communication and Jonah flying to a conclusion that Brighton was ashame of him. 
 The ending is a (view spoiler)[HFN (hide spoiler)] but I don't feel a lot of optimism for where they are and will be based on that last scene. 
 The writing is at times masterful. For example, the part where he describes Carly (the girl who just broke up with him) to Brighton. I just think that these characters and their story didn't work for me. I understand the 24 hour concept and why there wasn't any further glimpses but it wasn't satisfying as a romance.
