This would have been a spectacular book if the authors hadn't decided to spice things up with an unneeded supernatural element. I don't know if they thought the book needed something to make it stand out, or if they were going for a Carrie feel, but it ruined the whole thing for me. 
 In the beginning I kept getting all of the girls mixed up. I was irritated that there was some huge back story that kept being alluded to but not revealed, and I almost stopped reading. 
 I enjoyed the plot line, and I liked the characters, I just can't get over Mary being able to, I don't know, do stuff with her mind. Lame. Unneeded. Unwanted. They could make every person in that high school telekinetic in the sequel and I'd STILL think that it was the most ridiculous thing for the first novel. I expected more of you, Han, and you let me down.
