I love the world in this book. It is so interesting to hear about these different dystopian worlds authors create for their books. The main reason I pick up dystopians is because of the worlds. 
 The world is not as advanced as you would believe. Even in 2027 it's not that much more advanced and it makes the book seem so much more realistic than hover cars and time travel. 
 The main character's past is annoying because she is still obsessed with a boy. Once she's in the future she has a hard time moving on. #cultureshock (I can't remember names because I read it 3 days ago. It's been a while)
