First you think this is gonna be a teenage magic & love story:
Sophia Mercer (Sabrina the teenage witch-type) put a love spell wrong and is send to a kind of(in my opinion dilapidated version of) Hogwarts, where her roommate is a goth version of Cherri Creeper and a Coven of other dark witches (you get the impression of The Trix of Winx Club here) tries to intrest her to join them. Nothing special, you think.
But then the story becomes gloomier & more mysterious. There is death, there is love, there are dark family secrets, demons and (oh wonder) Sophia got an attitude sharper than a normal 16 years old high school witch.
And then you´ll come to the conclusion, that you like this book and can´t wait to read the second volume.
