There are parts in this book that are ok, the main character and her friend are a bit interesting and some mysteries kept me reading, but mostly this book is ridiculous. 
 The main character arrives at this boarding school in Chicago while her parents take a 2-year trip to Germany to do research. She's mopping around about her bad luck for two seconds until she mets her new BFF, a girl who appears to have secrets. Well, the relationship between these two is nice and funny, but a bit far-fetched. Why?, you'll ask. They become BFFs almost instantly. For the plot, that is important but, come on! But not only that friendship feels rushed... Everything in this plot is rushed. I understand that the book is very short and there's no way to develop the subplots or the characters in a better way, but you can introduce them a little bit better, and not as if a chunk of an unidentified substance, supposedly eatable, has just landed on your plate (do u get the image? I didn't have much sleep this night to be writing in English at 8 am xD). 
 Anyway, in the end the plot and the mystery and who the bad guys are were a bit too much of the eyes-rolling type (especially because the explanations were mostly WTF), but I might read the second book only to know what the mystery surrounding the MC's parents is xD Let see (said the blind man)! :)
