4.5 :) 
 I really liked this. The plot was actually pretty simple but it was written so amazingly well. 
 And the romance.... a slow build up of chemistry (me so love)...there was a period in the middle of the book when I was thinking "Do I really love this romance?" but then the rest of the book pretty much confirmed that I really really loved the romance. 
 AAnnnnddd.....I really want the sequel to hurry up and be released, I want more Ethan and Nara! :) 
 Definitely give this one a read :)
