I have read Fangirl by Rainbow Rowell last year and when you read this story you instantly recognize that this is the same author. There is also a lot of similarity in the story as well. 
 The blurb pretty much says it all. I have heard and seen the craziness when a Star Wars movie releases in the USA so I understand what Elena is expecting. But this story also shows us glimpses into Elena's school life and how her perception of herself is challenged by Gabe. 
 (view spoiler)[ The ending was hilarious. Both of them falling asleep after 3 days of sleeping on the street, no showering and peeing in cups (hide spoiler)] 
 All in all a cute story.
