Reread in June '15. 
 I love the world the authors have created, I love the characters but there is a glaring bit of plot stupidity that annoys me every time I read it. (view spoiler)[ The villain pretty much hands Kate a piece of paper telling her who the villain is (spoiler alert: him!) and explaining the mystery she is working on and she's like, "Hey that guy's creepy, not going to pay any attention to what he says". (hide spoiler)] I did, however, find that lines such as "Here, kitty, kitty, kitty" are much funnier having read the entire series ;)
