Déjà vu

Elizabeth was a quite ordinary girl; she was quiet, she read a lot, was often caught in class with music in her ears, polite, not really the girl to have any opinions. A little antisocial, an adult from the outside could happen to think, if they thought about her at all. Therefore no one understood wen she tried to take her life.
She is set on a strict road to recovery, however there is one little quirk. She suddenly have two therapists trying to solve her riddle and one of them is a teenage ghost boy named Miles.
They make a deal; she tells him about herself in order for him to help her, while he gives her clues on his murder, which Lizzie thinks might be the reason he is still around. After a while it turns out the cold murdercase isn't all that cold.

Warnings for very dark themes used with very bad humor. This is a comedy, but it's about other things, too.
