I was impressed by all her past works I've read, the quality of the language, the tension buildup.

In this one the ravings of a bunch of teenage, rich teenage girls with sentences such as "it as like, ewww, I don't know". So you could say that the ambience is well recreated but it sure makes for a long a boring read. At about 25% I went to read other reviews who all said it didn't get better until the end so I have to admit I left it at that.
