"Isa. Don't. Kill. Her. She's like, five."

Katherine Halloway was a regular sixteen year-old girl who only wanted to play in the rain. Then Casey Devner came along and showed her everything she was missing in life. Now she has to deal with demonic entities that want to take her body, this nut case of a neighbor, and a "holy" spirit who can barely stand not locking her jaws on Casey's seven year-old sister.

To add to this, Katherine begins having problems with her quiet social life when a cute boy decides he likes her. And Kat has Casey to thank for all of it.
