I know this book is intended for teen (as I stated repeatedly in my review of previous books), but it's annoying how there seems to be no two sensible character in every scene. When Mia was being cool-headed (which was not happen too often), she would be shouted at by the selfish, power-crazed Lilly. (view spoiler)[ it's good that in this book they ceased to be friend because honestly I don't know what's the point of befriending a girl who always bossed you around like that. (hide spoiler)] If the other party is being calm and and try to explain something, then we have our Princess freaked out of nothing! It's quite tiring to read, and considering this SHOULD be a light reading, that ought to count for something. 
 Also, If you are binge-reading this series, you will notice some details are inconsistent, especially with book 7. And far too many sex-centered diary entry for my liking, I start to question if it's really normal for a 15 years old teenager to know all this? Even in America?
