She's living inside me.

Elisia has always been aware that she is different from everyone else.
She is a socially awkward and doesn't seem to fit in. But there is something else... or someone else? For a week at a time her body is taken over by Eli, a evil spirit trying to find her way back into exsistance. This has been happening ever since Elisia witnessed her best friend brutally murdered. Quickly, her perfect school record is ruined and her relationship with her foster mum is beginnig to suffer. Can Elisia stop Eli taking over?
