3.5, or maybe a 3.75. I was very entertained, and learned quite a bit as I have from the previous books in this series, but Cece was just too... I found myself so annoyed by her lack of self esteem. And there were too many moments when I thought the writing just wasn't as well executed as in the first 3, like it was too rushed, making it hard to really connect with the characters and get lost in the story lines. I'm still looking forward to the others though.
