** spoiler alert ** 
 Ghostgirl meets Perfect Chemistry... But funnier than one and less cheesy that the other one, more down-to-earth despite the supernatural factor... 
 Although there are some weak points in the action and some other points that are just about believable (if you just read it and don't analyse it, it makes perfect sense), it's very entertaining. Loved the dialogues between the main characters: how she is always so harsh, rude and impatient (but without losing any bit of charm) and wants to get to the point quickly and he gets annoyed by her constantly, but at the same time cannot resist the attraction. 
 The ending was nice, I like the idea of the two together, although my head cannot think ahead and imagine how it would develop this relationship fO.o And beside I didn't get one thing: why exactly did she come back if she had already seen the light? Was it because of him?? Or didn't she cross to the other side completely? 
 Anyway the book is funny and well-written and if Ghostgirl was such a success, this one should be at least the same, because it makes sense and is way funnier xD
