"Five friends formed the clique that ruled the school - until their leader, Alison, went missing. Now, mysterious notes may bring old secrets to light." Nothing new or original here. The missing "Alison" was really her twin Courtney. This is neither the first nor the last time the tedious twin ruse has been used. Yawn. And that cover illustration - of the anorexic girl? Is this really the example we want to set? Barf.
