3.5! I really liked this one! 
 And that ending was actually perfect. I don't now if I would have liked it so much if you know it ended any other way:) 
 It was a bit annoying at times but not overly annoying. Amelia was a fun protagonist with some strong opinions! She was adorable and I think a good character to this sort of story! She's assertive, opinionated, mature & stuff. Yet, she clung to Chris desperately. 
 Not that I blame her, Chris is the sort of guy that is just perfect while being extremely flawed. He is charismatic, energetic, and, simply put, a nice guy. He gets along with everyone and is well-liked by everyone. I know one person who's like that. They make you feel special by simply giving you the honor of being their friend. Your day is brighten when they do something for you. It's so easy to fall in love with those sort of guys so I can understand Amelia! 
 Read this one in summer, it's a fun light summer-y read!
