4.5 stars. The first half of the book was great. It was this murder/mystery/whodunit? kind of thing and I COULD NOT put the book down! Then there's this HUGE plot twist where I was just like, "WHAT?!" But alas, eventually the shock wears off (pretty quickly actually) and then the book starts becoming lackluster. I'm not quite sure how I feel about the ending yet...I am disappointed with the second half of the book, though. Time to go watch the movie!
