Devilish by Maureen Johnson

Summary:(from book jacket). Jane Jarvis and Allison Concord, seniors at Saint Teresa's Preparatory School for girls, have always been too quirky to be popular, but at least they'll always have each other,right? Not so much. After a hideously embarrassing disaster, Allison comes to school transformed. Suddenly she has cute hair and clothes, speaks fluent Latin, and won't even look at Jane. With the help of a strangely wise freshman boy Jane discovers the incredible truth:Allison has sold her soul to the devil. Now Jane will have to save Allison  before the bizarrely exclusive Poodle Prom, a party of biblical proportions that just might blow apart the world as Jane knows it.
Review: I liked this book. It was a cute and fun way of telling this story. It wasn't a scary story by any means but I'm not really sure that it was supposed to be. I also thought that some of the plot points were really predictable which kind of takes away from it. The story also took a different turn than I expected it to regarding what actually changed about Allison after she sold her soul. I was expecting it be more of a typical ditch your best friend for the popular kids story but it wasn't and I liked that about it. the story was more focused on Jane trying to save Allison than the changes in their relationship which was refreshing because that story line had kind of been overdone.
  There weren't very many characters that I really liked in this book. All of the characters in this book were pretty predictable and simple. I didn't really fully connect with any of the characters. I did like Jane though, she was a simple narrarator but I really liked getting to know her throughout the story. I also loved the way that Jane is physically described in the book. It made her a little more memorable.
  Anyone who is looking for a simple, fun book to read should pick this up but if your expecting a scary story I suggest you lok somewhere else.
